煤化工自兴起以来带动了经济的快速发展，同时煤化工产生的直接损害就是二氧化碳（CO₂）排放量的增多。从现代煤化工发展现状、典型煤炭清洁转化过程的CO₂排放及捕集等方面详细阐述了现代煤化工的CO₂排放与利用，旨在为现代煤化工的碳减排提供思路。

Modern coal chemical industry has driven the rapid development of the economy since it rises.At the same time,the most direct hazard brought by modern coal chemical industry is the increasing amount of carbon dioxide emission.From the current development status of modern coal chemical industry and the emission and capture of CO₂ in typical coal clean conversion process,this paper describes the emission and utilization of CO₂ in the modern coal chemical industry,aiming to provide schemes for carbon emission reduction of modern coal chemical industry.
