烃类脱氢是一项重要的化学反应。随着石油化学工业特别是合成橡胶工业的发展,对合成橡胶单体二烯烃的需要量越来越大,因而烃类脱氢以制取二烯烃引起人们的普遍注意,丁烯直接催化脱氢制丁二烯便是这些研究中的重要成果之一。烃类脱氢不仅可以制取二烯烃,还可以制取烯烃、炔烃和芳烃。从化学平衡的观点可以知道,如果在反应中引入可以将氢气除去的所谓氢气“接受体”,则反应将向有利于脱氢的方向进行。可以作为氢气 Hydrocarbon dehydrogenation is an important chemical reaction. With the development of the petrochemical industry, especially the synthetic rubber industry, the demand for the synthetic rubber monomeric dienes is getting larger and larger. Therefore, the dehydrogenation of hydrocarbons to produce diolefins has attracted people’s attention. The direct catalytic dehydrogenation of butenes Butadiene is one of the important results of these studies. Hydrocarbon dehydrogenation can not only produce dienes, but also can produce olefins, alkynes and aromatics. From the viewpoint of chemical equilibrium, it is known that if a so-called hydrogen “acceptor” capable of removing hydrogen is introduced in the reaction, the reaction proceeds in favor of dehydrogenation. Can be used as hydrogen
