Introduction

煤化工行业已成为中国能源结构的重要组成部分，大型化规模化的煤化工项目不断涌现，煤制油、煤制烯烃、煤制二甲醚、煤制甲烷气、煤制乙二醇等等。同时各相关科研单位一直在探索煤炭高效清洁转化和石化原料多元化发展的新途径。

Coal-base chemical industry has become an important part of China's energy field, large-scale coal-base chemical projects continue to emerge, coal to oil, coal to olefins, coal to two -methyl-ether, coal to methane, coal to ethylene glycol, etc. mean while, the relevant scientific research institutions have been exploring new ways for the development of high efficiency and clean coal conversion and diversification of petrochemical raw materials.
