Application of honeycombed catalyst in flue gas denitration using selected catalytic reduction method

Abstract

Abstract: The domestic main energy source is coal; this situation would not change in the short term. Therefore, to reduce the NOx emission in coal fired flue gas is one of main research topics of environment protection technicians. The theory of selected catalytic reduction denitration was introduced. The characteristics of three kinds of catalyst were compared. The main factors influencing on the activity of the honeycombed catalyst (such as the reaction temperature, the ratio of ammonia and nitrogen, the velocity in empty tower, the high contents of calcium and sulfur) were analyzed. The application prospect of the honeycombed catalyst in coalfired power plant was expounded. 

Key words: honeycombed catalyst, selected catalytic reduction (SCR) method, catalyst activity, application
