Abstract
A catalytic converter for controlling automobile exhaust emissions was evaluated in California in 1964. Results from this fleet test and subsequent analysis of the spent catalyst are presented. Statistical analysis of dynamometer test results indicates a strong effect of tetraethyl lead content of the gasoline on activity decline. Analysis of spent catalyst revealed that both surface area and accumulated lead are major factors in activity decline. Above 100 m2/g a further increase in surface area at constant lead level resulted in a decline in activity.Keywords
