摘要:

我国C4资源非常丰富,其利用主要集中在烯烃。本文介绍了国内C4烃的来源、产量以及主要的利用途径。为了满足严苛的环保要求,国内大部分甲基叔丁基醚(MTBE)装置即将停产,采用叠合-加氢工艺生产异辛烷是取代MTBE的新技术路线。本文从叠合-加氢工艺的反应原理入手,针对国内外几种典型的已工业化应用的叠合-加氢工艺,从工艺技术特点、催化剂类型、产品的关键指标进行了综合分析;对叠合-加氢催化剂的研究进展进行了深入研究;对叠合-加氢工艺的发展前景进行了评述;针对叠合-加氢工艺目前存在的不足提出了今后研究方向。通过研究表明,叠合-加氢工艺是当下应对C4烃资源过剩、提高汽油质量、提高国内C4烃综合利用的重要途径。

Abstract:

The utilization of abundant C4 resources in China is mainly in olefins. This paper introduces the sources, production and the main utilization ways of C4 hydrocarbons in China. In order to meet the stringent environmental requirements, most merhyl tert-butyl ether (MTBE) plants in China will be shut down soon. The superposition-hydrogenation process is a new technology to replace the MTBE one in the production of isooctane. According to different reaction principles of the superposition-hydrogenation processes, this paper comprehensively analyzes the technological characteristics, catalyst types and key indicators of several typical industrial superposition-hydrogenation processes. The research progress of superposition-hydrogenation catalysts is deeply discussed and the development prospects and shortcomings of current superposition-hydrogenation processes are reviewed. The research shows that the superposition-hydrogenation is an important way to deal with the surplus of C4 hydrocarbon resources, and to improve the quality of gasoline.

Key words: C4 hydrocarbon, isobutene, superposition-hydrogenation process, isooctane, superposition catalyst, hydrogenation catalyst
