介绍了丙烷、异丁烷脱氢的反应机理和动力学,并对脱氢平衡转化率与温度、压力的关系,H2分压、空时对小分子烷烃在铂(Pt)系催化剂上脱氢的影响进行了综述。指出脱氢是一个高能耗的反应过程,提高单程转化率是降低脱氢能耗最有效的手段,单程转化率与操作条件和催化剂密切相关。
The reaction mechanism and kinetics of dehydrogenation of propane and isobutane were introduced. The relationship between the dehydrogenation equilibrium conversion rate and temperature and pressure, H2 partial pressure and space time were investigated. The dehydrogenation of small alkane on platinum (Pt) catalyst The impact of It is pointed out that dehydrogenation is a highly energy-consuming reaction process. Increasing one-way conversion is the most effective way to reduce the energy consumption of dehydrogenation. One-way conversion is closely related to operating conditions and catalysts.
