摘　　要：概述乙烯主要的生产工艺如蒸气裂解制乙烯、石脑油催化裂解制乙烯、重油催化裂解制乙烯、炼厂气干气制乙烯、C_4制乙烯、甲醇制乙烯、乙醇制乙烯、甲烷制乙烯、合成气制乙烯和生物法制乙烯等。主要比较工艺特点、反应机理、催化剂以及典型工艺等方面。认为由于原料的差异,煤基工艺发展相对较为成熟,石油基工艺发展相对缓慢,利用煤基乙烯生产工艺和催化剂将有助于开发石油基的工艺和催化剂。Main technologies of producing ethylene,such as,steam cracking,naphtha deep catalytic cracking,heavy oil deep catalytic cracking,separating of refinery dry gas,C4 deep catalytic cracking,methanol to olefins,ethanol to olefins,methane to ethylene,syngas to ethylene,biology technology and so on were summarized. Especially,technology characteristics,reaction mechanism,catalysts and typical technologies were compared. According to the comparison,coal based technologies were more developed than the oil based because difference of feed stock. By taking advantage of the coal based technologies,the oil based technologies would become more important and applicable.
