摘要: 介绍了当前几种主要的天然气制乙烯技术新进展,包括天然气经甲醇制乙烯、费-托合成制乙烯、甲烷氧化偶联制乙烯技术进展及应用情况,并对这几种工艺进行了技术经济评价,结论认为:天然气制乙烯技术的大规模应用,主要取决于天然气原料供应的有效保障及其价格是否合理,在天然气供应充足、价格合理的条件下,天然气经甲醇制乙烯工艺将会得到较快发展,而费-托合成制乙烯、甲烷氧化偶联制乙烯技术目前尚未达到成熟应用阶段,需要持续加大研发力度,争取早日实现工业化应用。

Abstract: The current main technology progress of natural gas to ethylene were introduced,including natural gas to ethylene through methanol,Fischer-Tropsch synthesis route,and oxidative coupling of methane. Technical and economic evaluation of these processes were performed,and the conclusions are:the large-scale application of natural gas to ethylene technology mainly depends on the natural gas supply and it's price. Under the conditions of sufficient gas supply and reasonable price,the technology of natural gas to ethylene through methanol will get a rapid development,while the applications of Fischer-Tropsch synthesis and oxidative coupling of methane technology at present has not yet been mature and it is necessary to continue to intensify their research and development for the realization of their industrial application.

Key words: natural gas, ethylene, methanol, Fischer-Tropsch synthesis, oxidative coupling of methane, technical progress, economic evaluation
