Abstract:

Results of research on a two-dimensional, transient catalytic combustion model and on a high-temperature perovskite catalyst are presented. A recently developed two-dimensional, transient model has been used to study the ignition of COair mixtures in a platinum coated catalytic honey comb. Comparisons between calculated and measured steady state substrate temperature profiles and exhaust gas compositions show good agreement. A platinum-doped perovskite catalyst has been designed to exhibit low temperature light off and high temperature stability. Preliminary tests using a perovskite powder with one percent by weight platinum are encouraging, showing very little change in surface activity when used with propane fuel. Author
