陶氏化学公司的启动计划涵盖了几种替代原料制化学品路线,包括合成气路线。从合成气生产烯烃业已开发出来,但投资密集。避开合成气,从甲烷直接转化为烯烃作为工业目标提出已有几年时间。人们正在进一步开发以使其在技术上可行,通过可行的工艺过程使甲烷偶联以制取乙烯,对开发偏远天然气资源将具有重大优点。 Dow Chemical’s start-up plan covers several alternative feedstock chemical routes, including the syngas route. Alkenes have been developed from syngas but are heavily invested. It has been several years since industrial gases were avoided to bypass syngas and convert directly from methane to olefins. People are further developing to make them technically feasible, coupling methane to make ethylene via a viable process, and will have significant advantages in developing resources for remote natural gas.
