在国家相关部门多次强调要调整能源结构的大背景下,煤制气、煤制油等众多煤化工技术路径开始火起来。煤制气项目的环境贡献集中体现在,在同等数量煤炭消费的情况下,可以更为有效地控制NOx、SOx和粉尘等,这符合我国推广使用洁净能源,降低污染物排放强度的能源政策。但是,在煤 Under the background that the relevant state departments repeatedly stressed the need to adjust the energy structure, many coal chemical technology routes such as coal gasification and coal oilification started to fire up. The contribution of coal gas projects to the environment is mainly embodied in the fact that NOx, SOx and dust can be more effectively controlled under the same amount of coal consumption, which is in line with China’s energy policy of promoting the use of clean energy sources and reducing the emission intensity of pollutants. But in coal
