Detection of catalyst used in SCR system of a thermal power plant before and after operation and data analysis

Abstract

Abstract: Abstract:The SCR denitration technology is domestic main technical means for NOx emission reduction. The chemical components and main parameters of the SCR denitration catalyst were introduced. The mechanical strength, the specific surface area, the pore volume and the pore diameter of the SCR denitration catalyst were expounded. The main chemical components, the abrasion strength, the compressive strength and specific surface area data of the SCR denitration catalyst of a thermal power plant were detected The detected data of two layer catalyst before installation and after puting into operation were compared and analyzed. The rationalization proposals of catalyst operation and management were put forward.

Key words: Keywords:selective catalytic reduction (SCR) deNOx equipment, catalyst, mechanical strength, denitration, activity
