IMPROVED PELLETED CATALYST SUBSTRATES FOR AUTOMOTIVE EMISSIONS CONTROL

An in depth analysis of the pelleted automotive catalysts from the 1975 General Motors Certification Fleet led to the development of a useful catalyst poisoning model. By optimizing three variables, it was possible to design a more poison resistant catalyst. The application of these ideas resulted in a second generation of catalysts. In order to meet 1980 and 1981 emissions requirements, further improvements were required. To achieve this, two different variables were studied: geometric surface area and noble metal ratios.
