摘　　要：我国是一个贫油富煤的国家,且高硫煤所占比重很大,煤炭燃烧产生的SO2是导致酸雨形成的主要原因,我国镁工业每年排出大量的镁还原渣,镁渣中含有大量的碱金属氧化物,完全可以用作燃煤的固硫剂。本文通过实验室的实验,试图证明镁还原渣用过燃煤固硫剂的可行性,并初步探索出最佳的固硫条件。China has a large amount of coal, but shortage of petroleum. And a large part of the coal in China is the high - sulfur coal. The SOz produced by the burn coal is the main reason to cause the acid rain. As the increase of the productivity of the magnesium,the output of the magn^ium slag increased. There is a lot of oxide alkali metals in magnesium slag,and it can totally used as sulfur dioxide sorbent.This article try to prove the possibility of this,and seek for the best condition of magnesium slag used as sulfur dioxide sorbent.
