The prototype expert system ESYCAD (expert system for catalyst design) was set up for assisting in the design of heterogeneous catalysts. It selects materials as catalyst components which have all required properties for the various (elementary) steps of a target reaction but which do not catalyze undesired side reactions. If necessary, also secondary catalytic components or promoters are selected; furthermore, reaction conditions are proposed if required by catalyst properties. The application of the system is illustrated by examples for CO-hydrogenation, alkane dehydrogenation, and for oxidative coupling of methane.
