摘　　要：从热力学和反应机理角度概述了异丁烷直接脱氢和氧化脱氢的差异;从活性中心性质、失活与再生、助催化剂以及载体方面综述了目前广泛研究的异丁烷直接脱氢制异丁烯的催化剂,包括PtSn-、CrO_x-、GaO_x基和金属硫化物催化剂,并分析了各类催化剂的优缺点及目前的研究方向。简述了其他类型的脱氢催化剂,包括Mo/MgAl_2O_4、碳基材料、Co-、Ni_2P-、VO_x基催化剂等。分析了目前脱氢技术面临的问题以及未来的研究方向。The differences between isobutane direct dehydrogenation and oxydehydrogenation were summarized from the perspective of thermodynamics and reaction mechanism. The catalysts for the direct dehydrogenation of isobutane to isobutene,including Pt Sn-、Cr O_x-、Ga O_x-base and metal sulfide catalyst,are reviewed in terms of the nature of active center,deactivation-regeneration,the promoters and carriers. The advantages and disadvantages of the catalysts and the current research direction were analyzed. Other types of dehydrogenation catalysts were summarized,including Mo/MgAl_2O_4,carbon-based material,Co-,Ni_2P-,VO_x-based catalysts,etc. The problems of current dehydrogenation technology and the future research direction were analyzed.
