Title: (EN) Process for the production of ethylene
(ZH) 生产乙烯的方法
Abstract: front page image
(EN) The invention relates to a process for the production of ethylene, comprising the steps of a) thermally converting, by a pyrolysis or a partial oxidation process, a feed charge containing methane into an acetylene containing effluent, and b) in situ hydrogenating, by a non-catalytic reaction, the acetylene produced in the first step into ethylene by intimately mixing the acetylene containing effluent with an ethane feed. The process according to the invention is more efficient than other synthesis schemes, while simplifying the overall process design. This process thus offers an economically attractive scheme for mass production of ethylene from natural gas, based on a well-known and proven acetylene route.
(ZH)

本发明涉及生产乙烯的方法,该方法包括下述步骤:a)通过热解或部分氧化法,热转化含甲烷的原料进料成含乙炔的流出物,和b)通过紧密地混合含乙炔的流出物与乙烷原料,通过非催化反应就地氢化在第一步内生产的乙炔成乙烯。本发明的方法比其他合成流程更加有效,同时简化总的工艺设计。该方法因此提供经济上吸引人的流程以供基于公知和被证明的乙炔路线,由天然气批量生产乙烯。
