Abstract

Abstract: To ensure the normal operation of DeNO_x system, it is necessary to evaluate the DeNO_x catalysts performance for coal-fired power plants. In this paper, the inadequacies in the related standards, i.e. Honeycomb-Type DeNO_x catalysts(GB/T 31587-2015) and Testing Guideline of SCR Catalyst for Thermal Power Plants(DL/T 1286-2013), are discussed regarding those inconsistent with the practical situations. In order to improve the honeycomb-type SCR DeNO_x catalyst performance testing, suggestions are put forward in this paper such as supplementing testing on the dispersion uniformity of the active components on the catalyst surface, weakening the ammonia slip testing, etc. It is also advised to improve the quantified indices for SO₂/SO₃ conversion rate evaluation and establish the specifications for testing equipments and samples.

Key words: coal-fired power plant, De-NOx, honeycomb-type catalyst, testing apparatus, specifications
