Catalyst life prediction method and catalyst life analyzer

摘要

PROBLEM TO BE SOLVED: To provide a catalyst life prediction method and a catalyst life analyzer for analyzing catalytic performance at each position and predicting catalyst life, even when deterioration in catalytic performance is not uniform and varies with each position in the catalyst layer, like a chemical reaction process using a catalyst comprising a fixed bed circulation type catalytic reaction tower.SOLUTION: Provided are a catalyst life prediction method and a catalyst life analyzer that, in a chemical reaction process using a catalyst comprising a fixed bed circulation type reaction tower, calculate change in catalytic performance as a change amount of activation energy on the basis of a total amount of a target product within a use period of a catalyst, and that analyze temporal change of the catalytic performance from the change amount of the activation energy in order to predict catalyst life.SELECTED DRAWING: Figure 1
