正丁烷一步脱氢异构催化剂进展

Advances in the Catalysts for Dehydroisomerization of n-Butane

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.
