煤化工工艺技术评述与展望rn Ⅱ.合成乙烯和二甲醚

摘要

评述了由合成气合成乙烯和二甲醚的研究进展和工业开发状态，比较和讨论了合成乙烯和二甲醚的各种工艺路线，提出我国合成乙烯和二甲醚的工业开发方向。%The status of research and development for the synthesis of ethene and dimethyl ether(DME) from syngas derived from coal and natural gas is reviewed. Some technical processes for the synthesis of ethene and DME are compared and discussed, and then the direction of the industrial development for their synthesis is proposed.
