Abstract

An integrated method has heen suggested aiming at the investigation of multiple states of effectiveness factor for cylindrical catalyst pellet. It includes; (1) Finite - Element Global Analysis

which is the combination of Finite -Element Method with Continuation Method and singularity theory

is used as a basic tool to deal with the multiple solutions of partial differential equation. (2) a new numerical method for large -value effectiveness factors

which overcomes the shortcomings of traditional methods and owns features of efficiency and accuracy

has been developed. Finite -Element Global Analysis is tested by experiment data and the agreement is satisfactory.
