SUBJECT: Fincil Report for Work Assignment No. B-8, Contract 68-03-3353,
"Catalyst Evaluation (Cert. FY 87)," SwRI Project 03-1193-008
This work assignment was intended to evaluate the condition of catalysts
removed from in-uue vehicles. The catalysts were removed by EPA from 1983
Model Year In-Use Technology Assessment (IUTA) vehicles, and one low-mileage in-
use vehicle. Eleven catalysts were analyzed under this work assignment. The
catalysts represented monolith technology. Catalysts used by several different
manufacturers were included in the evaluation. The catalysts were either three-way
or three-way plus oxidation catalysts, with dual biscuits.
This letter report, along with the included data, is intended to be the final
report of the results from the catalyst evaluation testing. It includes all the results
from the laboratory analyses by whole converter x-ray, BET surface area, x-ray
fluorescence (XRF). proton induced x-ray emission (PIXE), and x-ray diffraction
(XRD). Only a brief discussion of the analytical procedure, and no discussion of the
trends observed in the evaluation of each catalyst, is included. A total of 11
converters (4 whole and 7 partial samples) were examined. A list of the converters
evaluated in the program is presented in Table 1. Only two of the converters
underwent whole catalyst x-ray; two had been x-rayed in a previous work assignment
(A254/0037 and A254/0191). Of the eleven converters, two underwent XRF, XRD,
and PIXE of the re.ir biscuit, and nine received all of the analytical procedures.
Only the rear biscaits were analyzed by XRF. A detailed description of the
laboratory analytic.il procedures is presented in the final reports for Work
Assignments No. 10 and 17 of Contract 68-03-3162, with the exception of PIXE.
L Laboratory Aiuilysis
The laboratory analysis of the catalyst samples consisted of whole converter
x-ray, BET surface area, x-ray fluorescence (XRF) , PIXE, and x-ray diffraction
(XRD). The catalyst samples were examined as follows:

2.	The whole converters were visually inspected, weighed with and without
any heat shields, and then carefully cut to expose the catalyst material.
All cat ilyst samples were visually inspected and weighed.
3.	Each converter was disassembled in a manner to expose the catalyst
materiid with a minimum of disturbance.
a.	In step one, the catalyst was sectioned into quarter pieces. The
upstream biscuit of the catalytic converter was sectioned as
pictured in Figure 1. Each quarter has a length "L" the same as the
length of the original uncut biscuit, but a height and width half of
tie original height and width (1/2H and 1/2W).
b.	In step two, one of the quarter sections was further sectioned into
three pieces as shown in Figure 1. The front piece had a length of
0.5 inch, the rear piece had a length of 1.0 inch, and the middle
piece had a length of "L - 1.5 inches." From the center of the
middle piece, a 0.5-inch sample was taken. Each of these three
0.5-inch samples underwent surface area analysis. The opposite
quarter was submitted in its entirety for (XRD) analysis. Samples
wure scraped from an area no larger than 0.25 cubic inches along
the center line of the catalyst. One sample each was taken 1 inch
from the front and rear faces, and the third sample was taken at
the midpoint of the length of the substrate and 0.5 inch from the
outside surface.
c.	Tv/o of the quarter sections shown in Figure 1 were not subjected
to any immediate analysis when a whole catalyst was supplied.
These samples were kept as additional material for future analysis.
Partial catalyst samples were sectioned starting with step two.
d.	The downstream biscuit was sectioned by cutting the substrate into
quarters similar to the upstream substrate. One sample each was
taken 0.5 inch from the front face and the rear face as shown in
Figure 2. Each of these two pieces underwent BET surface area
analysis. The remaining middle section was submitted for XRD.
The XRD samples from the B biscuit were scraped from an area
no: larger than 0.25 cubic inch along the center line and 1.0 inch
frc>m the front face. This was the only sample for XRD from the B
biscuit. The entire quarter section positioned diagonally from the
section used for BET surface area analysis was used for PIXE
an.dysis. The remaining two quarter sections from the four whole
converters (when provided) did not undergo analysis at this time,
bul were saved for future work.
A. Sample Identification
For the purpose of identifying the converters analyzed in this program, each
converter was designated with the seven or eight digit EPA identification code.
Once the converters were opened, the upstream biscuit was labeled "A," and the
downstream biscuit was labeled "B." Each quarter section from the A biscuit was
designated according to its location within the can (UL-upper left, UR-upper right,
LL-lower left, LR-lower right). The samples for BET surface area and PIXE were

also designated with respect to their locations in the biscuit. The location along
the length of the quarter section was labeled 1, 2, or 3, respectively, for the
upstream, middle, or downstream position. The exception to this rule was for the B
biscuit; no middle :>ample was taken for the BET surface area analysis. In this case,
"2" indicated the downstream location. The labeling designations are listed in Table
2.	The term "biscuit" is used to refer to each individual piece of ceramic
honeycomb materi.il in a converter.
B.	Whole Catalyst X-Ray
Two of the converters were examined by whole catalyst x-ray (A280/0005L
and A246/0092)- The other two whole converters in this work assignment
(A254/0037 and A254/0191) were examined by whole catalyst x-ray in Work
Assignment No. 20 of EPA Contract 68-03-3192. The radiographs taken in this work
assignment are included in Appendix A. Both converters appear normal. Converter
A246/0092 had several couplings welded to the outside of the case with
thermocouple connectors. Upon careful examination, the positions of the holes
drilled for the thermocouples cam be observed in the radiographs.
C.	Sample Weighing
The weights of the various samples were determined in several stages. All of
the whole convertsrs were weighed whole, and each biscuit was weighed after
opening. All of the partial samples were weighed, but these weights are only a
determination of the amount of sample received. In order to do additional
calculations on th«»se converters, the weights of the biscuits before the samples
were taken must bt- known or estimated. All of the weights are presented in Table
3.
D.	Visual Inspection
Each whole converter and biscuit was inspected for visual signs of overheating
or damage. Catalyst A230/0734-A was severely melted. A large void had developed
about two inches from the front face. This was the only visible example of melting
in this work assignment. Several samples had developed cracks. They were:
A221/0310-A, A220/0400-B, A230/0649-A&B, A230/0734-B, A246/0092-A&B, and
A240/0270. Catcilyst A246/0092 had been drilled in an effort to place
thermocouples into the center of the biscuit. All of the catalysts showed typical
signs of usage (dark front faces with rust on outer surfaces).
E.	Specific Surface Area
The specific surface areas of the whole length of all biscuits were measured
with a Micromeritics Flowsorb II dynamic surface area analyzer using the multipoint
analysis technique. This analysis was conducted "in-house" during this Work
Assignment. The advantages for "in-house" analysis include a stricter control of the
analytical procedures, ease of repeating questionable samples, and assurance that
the analysis is performed on a sample that represents the entire length of the
biscuit. Losses in surface area are due to thermal degradation and/or plugging of
the sub-microscopic pores with metals and other deposits. A loss in the active
surface area results in the reduction of contact between exhaust gases and the
catcilyst material. A low surface area generally indicates converter overheating.

Conversely, a normal surface area does not necessarily indicate a normal catalyst,
because the depos ts can increase the apparent surface area while covering the
surface and preventing contact with the exhaust gases. In this work assignment, the
surface area of O.'i inch pieces from the front, middle, and rear of the upstream
biscuit and the surface area from the front and rear pieces of the downstream
biscuit were analyzed. These large wedges were placed in a large sample tube and
analyzed whole. The sample tube consisted of a large tube with a ground glass joint
in the middle, or the sample was entirely sealed in glass. Either method was equally
effective, except the tube with the ground glass joint experienced a problem with
breakage. In order to eliminate this problem, all subsequent samples were sealed in
glass.
Upon completion of the analysis of the LL1 piece, the sample was ground to a
coarse powder (approximately 100 mesh). This sample was also analyzed for surface
area. The results for the specific surface areas are presented in Table 4. The plots
for the BET equation versus the relative pressure for each converter are included in
Appendix B.
F.	X-Ray Diffraction
X-ray diffraction analysis of the samples was used to determine the crystal
structure of the alumina. Gamma-alumina and several other very similar alumina
structures are the original crystal structures used in the alumina washcoat. When a
catalyst containing these types of alumina is overheated (temperatures greater than
1000°C), the crystal structure changes to the alpha-alumina form. This conversion
in crystal structure can trap the active metals and change the active surface area of
the catalyst. The Debye-Scherrer powder x-ray diffraction technique was used to
determine the alumina crystal structure. This technique is well suited for the
analysis of monolith catalysts because of the small quantities of sample required. In
the case of monolith catalysts, the alumina is deposited as a thin wash-coat on the
surface of the cereimic substrate. The alumina can be scraped off carefully and
analyzed. The x-ra^s are diffracted by the various crystalline compounds within the
sample. Each crystalline compound has a characteristic diffraction pattern.
Amorphous compounds do not result in a diffraction pattern. These patterns are
compared to known compounds in a Powder Data File for identification. Table 5
lists the alumina crystal structure of each sample and any other crystalline
compounds observed in the samples.
G.	Proton Induced X-Ray Emission
Proton induced x-ray emission (PIXE) was used to determine the
concentrations of noble metals and the accumulation of poisons. This technique
utilized protons to "knock" electrons from the inner orbital shells. The electron
removed causes the element to fluoresce x-rays at characteristic wavelengths.
These fluoresced x-rays are detected, and they represent the quantity of each
element present in the sample.
The elements of concern were phosphorus (P), sulfur (S), calcium (Ca),
manganese (Mn), zirc (Zn), lead (Pb), platinum (Pt), palladium (Pd), rhodium (Rh),
and nickel (Ni). The elements P, S, Ca, Mn, Zn, and Pb are poisons or contaminants.
They are derived from engine wear, dirt deposits, oil, fuel, and other sources. The
noble metals are Pt, Pd, and Rh, and they perform the function of "deeming up" the
exhaust. Nickel was found in some converters, and is reportedly present to enhance

the catalytic activity. Aluminum (Al), silicon (Si), and magnesium (Mg) are major
constituents of the support material, and were not quantitatively determined. The
minor constituents such as sodium (Na), potassium (K), titanium (Ti), iron (Fe),
cerium (Ce), and b irium (Ba) were also not quantified. The elements Na, K, and Ti
are present in small amounts from the clays used to make the cordierite ceramic.
Titanium is also probably present in the converters as a whitening agent for the
ceramic substrate. Cerium was added to inhibit the conversion of gamma-alumina
with a higher surface area to alpha alumina with a lower surface area at the
elevated temperatures experienced within the converters, and also to increase the
catalytic activity of the converter when present in concentrations of one percent or
more. Iron was probably from the engine, as a wear product, the exhaust system
due to rust, or as

accuracy and precision of the results presented in this report. A listing of
precision, accuracy, and completeness is presented in Table 9. All measurements
are representative oi the catalyst properties and conditions being measured.
The Micromeritics Flowsorb II dynamic surface area analyzer was set up to
analyze the catalyst samples "in-house." Two NBS Standard Reference Materials
and seven standards from Duke Scientific Corporation were used to establish the
instrument operatiig range and linearity, as well as confidence in the analytical
procedure. In this work assignment, the surface areas were determined with a
multipoint technique. A curve was established for the various gas concentrations to
determine the calibration knob setting for the instrument (Figure 3). The standards
were analyzed using this technique, and the results are given in Table 10. A plot of
the BET equation versus the relative pressure for the standards is presented in
Appendix D. In general, the standards repeated within the published confidence
limits for the entire range of standards (0.62 m^/g to 265 m^/g).
In an effort :o correlate the data from this work assignment with previous
work assignments, an alternative procedure for preparing the samples for surface
area was used. The coarse powder (approximately 50 mesh) from ten samples was
analyzed for surface area and compared to the results for the bulk strips which were
cut from the center core of the biscuit and analyzed as a single sample. The results
for the two sampling techniques are-presented in Table 11, and the plots of the BET
equation versus the relative pressure are included in Appendix E. The surface areas
for the ground samples were lower in all cases except for A220/0810-A, A221/0447-
A, and A155/0941-1-A. All three of these samples were from the A biscuits. The
A220/0810-A was tie only sample from the group which contained alpha alumina.
The other two catalysts were from Chrysler vehicles. Ground catalyst samples from
the upstream biscu t apparently result in higher surface areas than the unground
samples. These results were also observed for front face samples listed in Table 4.
No conclusions can be drawn without additional work to confirm the sources of this
phenomenon.
In an effort to demonstrate the precision and accuracy for the XRF procedure,
a sample analyzed in Work Assignment No. 20 from EPA Contract 68-03-3192 was
selected at random and repeated during this work assignment. The results are listed
in Table 12 and Figure 4. In general, the current results agreed very well with the
previously published results. The largest error was for Ni, but the concentration was
so low that the error does not indicate a significant problem. When Ni is excluded,
the average percent difference is 0.3 i 3.8. Phosphorus and lead values were higher,
while sulfur and pla.inum were lower. The precision and accuracy for XRF depend
on the concentration of the elements, the elements present, the homogeneity of the
sample, and the size of the particles in the pellet.
V. Summary
In summary, a total of 11 catalysts were examined by whole converter x-ray,
x-ray fluorescence, x-ray diffraction, PIXE, and BET surface area analysis. Of
these 11 catalysts, 4 were whole converters and 7 were partial catalyst samples.
This letter report is a compilation of all of the data available at the time of
submittal, and is intsnded to serve as the final report of the results for the program.
