摘要
乙苯脱氢技术是苯乙烯的主要生产方法。简要介绍了3种主要的乙苯生产工艺:气相法烷基化工艺、液相法烷基化工艺、稀乙烯原料制乙苯工艺的工艺特点、原理及国内外研究进展。在此基础上,对苯乙烯生产技术,如绝热负压脱氢技术、苯乙烯与环氧丙烷联产工艺的研究状况和主要技术指标进行了论述,并指出了苯乙烯生产技术的发展方向。
The process of ethylbenzene dehydrogenation is a mainly method for the production of styrene nowadays. The characteristic, principle and the advances of three processes at home and aboard for etylbenzene production, including benzene alkylation in gas phase, benzene alkylation in liquid phase, and the process with dilute ethylene as a raw material, are introduced .The research status and the main indexes of several technologies for the production of styrene such as the dehydrogenation process under the conditions of heat insulation and negative pressure, and the process for the co-production of styrene and epoxy propane, are reviewed. The development trends of the technology for manufacturing styrene are also pointed out.
