二氧化硫的催化净化技术

Review On Catalytic Purification Techniques of the Sulfur Dioxide.

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。

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.
