【二年级数学教学论文】论文关键词:甲烷氧化偶联 乙烯 电能 联产论文摘要:甲烷氧化偶联反应(OCM)的提出为由资源丰富且相对廉价的天然气替代主要由石脑油制取乙烯提供了新的可能途径,并且该途径是通过一步法制乙烯,是现有乙烯生产工艺中最为简捷的途径。但是由于甲烷化学性质稳定,使甲烷氧化偶联制乙烯的转化率一直无法突破30%(最低的工业生产要求)。近期研究发现,可以利用OCM反应放出的热量来实现乙烯生产和发电的结合,以提高它的经济效益,增加实现工业化的可能性。本文介绍了有关OCM的先进技术,并主要对OCM反应热量的利用进行了分析,提出生产高温高压蒸汽,实施冷热电联产。 Key words:oxidative coupling of methane;ethylene;electricity;co-generation Abstract:The reaction of oxidative coupling of methane(OCM)provides a new possible way to produce ethylene by rich and cheap natural gas instead of naphtha as raw material. It gains ethylene by one step,which is the simplest and directest in producing ethylene nowdays. However,methane is very steady,so the yield of ethylene can not break through 30%,which is the lowest request in industry. But recent studies have claimed that this may be overcome by producing not only ethylene but also electricity by making use of the heat f
