二氧化硫的催化净化技术

长期以来我国的能源结构以煤炭为主,煤燃烧时会生成SO2、Nox,由此造成了严重的大气污染,降雨酸化。催化脱硫法作为一种新型技术,脱硫成本低、脱硫率高,可满足日益严格的环保要求。本文分燃烧前脱硫、燃烧中脱硫、烟气脱硫三个部分并分别介绍了催化脱硫的研究进展及应用。

Review On Catalytic Purification Techniques of the Sulfur Dioxide.

The energy structure of our country takes coal as the core for a long time,the coal produces SO2,NOx while burning,which made the serious air pollution and the acidified rainfall.As a new kind of technique,catalytic desulphurization whose cost is low and rate is high,can meet the strict requirement for environment protection increasingly.This thesis is divided into three parts----desulphurization before burning,desulphurization while burning and flue gas desulphurization----and introduces some studies on developing and application of catalytic desulphurization respectively.
