摘要
综述了正丁烷一步脱氢异构催化剂的研究现状。目前,正丁烷脱氢异构催化剂可以分为两类,过渡金属双功能催化剂和过渡金属氮化物、碳化物和碳氧化物催化剂。指出了丁烷一步脱氢异构反应对催化剂载体酸性和孔结构的要求,以及两类催化剂各自催化转化烷烃的机理,并提出了两类催化剂的研究方向。
The studies in the catalysts for dehydroisomerization of n-butane are reviewed. The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals. The pore structure requirement to the reaction of butane one-step dehydrogenation for the acidic supports of catalysts and the catalytic reaction mechanisms are described. The future development of the two kinds of catalysts is prospected.
