【摘要】：异丁烯市场的迅猛发展,促使异丁烷氧化脱氢制异丁烯技术得以重视,商业化的Pt基和CrO_x基催化剂存在的不足,使得对新型脱氢催化剂的研究开发成为热点。本文简述了异丁烯市场及发展前景,概述了异丁烷氧化脱氢制异丁烯技术的发展现状,综述了目前文献广泛报道的异丁烷氧化脱氢制异丁烯催化剂的类型(包括MoO_x基、VO_x基、In_2O_3基、Ni基催化剂和单原子催化剂)、活性物种及研究方向,并分析了上述催化剂的优缺点。分析发现,金属氧化物催化剂制备方法传统易行,但产物烯烃收率和稳定性等方面仍待提高,与之相比,单原子催化剂只含有一种活性金属原子,降低了金属负载量的同时提高了其利用率,具有巨大的研究前景。制备方法和实际应用性是未来单原子催化剂的研究重点。
[Abstract]:With the rapid development of isobutene market, the technology of oxidative dehydrogenation of isobutane to isobutene has been paid more attention. The shortage of commercial Pt and CrO_x catalysts has made the research and development of new dehydrogenation catalysts a hot spot. In this paper, the market and development prospect of isobutene are briefly described, and the development status of the technology of oxidative dehydrogenation of isobutane to isobutene is summarized. The types of catalysts for oxidative dehydrogenation of isobutane to isobutene (including MoO_x / VO _ x based / InS _ 2O _ 3 / Ni-based catalyst and monatomic catalyst), active species and their research directions are reviewed, and the advantages and disadvantages of the above catalysts are analyzed. It is found that the preparation method of metal oxide catalyst is traditional and feasible, but the yield and stability of olefins still need to be improved, compared with the single atom catalyst, there is only one active metal atom in the catalyst. The metal load is reduced and its utilization rate is improved, so it has a great research prospect. The preparation method and practical application are the focus of monoatomic catalyst research in the future.
