Expert system approach to the preparation of supported catalyst

Abstract A prototype expert system, IACES, was developed for the selection of operation parameters in the preparation of supported catalysts. To prove the reliability of expert system approach to solving catalytic engineering problems, the system, at first, was designed some parameters of impregnation processes in aqueous solutions. Furthermore, the following pretreatments such as drying and activation were considered in a simplified manner to illustrate the ability of the expert system combining with numerical techniques. For several examples of the preparation of supported catalysts, the expert system behaved very satisfactorily, leading to the preparation parameters closely in agreement with those in practice.
