炼厂干气含有的乙烯和丙烯的回收利用是重要的研究课题,具有潜在的经济效益.除了深冷分离这部分烯烃的方法外,国内已有直接用于烃化为乙基苯,进而脱氢为苯乙烯的研究.我们曾以铑膦络合物为催化剂,在均相反应体系中以丙醛、丁醛为目的物进行干气中乙烯和丙烯的转化研究,本文又将担载液相铑催化剂(SLPC)应用于干气的醛化反应,不仅可使反应在气相流动状态下进行,克服了均相催化反应催化剂回收利用
Recycling of ethylene and propylene contained in refinery dry gas is an important research topic with potential economic benefits.In addition to the method of cryogenic separation of this part of olefins, it has been used directly for the alkylation of ethylbenzene in China, Hydrogen for the study of styrene.We used rhodium phosphine complex as a catalyst in the homogeneous reaction system to propionaldehyde, butyraldehyde for the purpose of dry gas in the ethylene and propylene conversion studies, this paper and the carrier liquid The rhodium catalyst (SLPC) used in the hydroformylation of dry gas not only allows the reaction to be carried out in the gas-phase flow state, but also overcomes the problem that the homogeneous catalytic reaction catalyst is recycled
