Document Type and Number:
Japanese Patent JP6164718
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a deterioration regeneration predicting program of a denitration catalyst using a reaction model summarizing the deterioration and the regeneration of the denitration catalyst.SOLUTION: In the deterioration regeneration predicting program of a denitration catalyst, the setting of parameters of an ammonium based reducing agent is carried out by a computer, the condition setting of the denitration catalyst is carried out, the reaction quantity of ammonium and the reaction quantity of nitrogen oxide by the denitration catalyst are calculated, the generation quantity of sulfur trioxide by the denitration catalyst is calculated, the increasing and decreasing quantity of acidic ammonium sulfate by the denitration catalyst is calculated, the performance degradation quantity of the denitration catalyst is calculated, and the calculated result is output.
