| 摘 要： | 介绍异丁烷脱氢制备异丁烯Pt系催化剂的研究进展,表明催化剂的活性中心、载体和助剂对异丁烷脱氢反应性能影响较大。催化剂活性中心的积炭覆盖和烧结是催化剂失活的直接原因;载体的酸性有助于调变积炭的形成速率,而活性中心与助剂的交互作用可促使积炭的表面迁移;活性中心与载体的交互作用有利于减少活性中心的烧结。

| Abstract: | Research progress of Pt-based catalysts in the catalytic dehydrogenation of isobutane is systematically summarized.It is believed that the nature of the active sites,supports,and promoters have great influence on dehydrogenation of isobutene.Carbon deposition and sintering of the active sites in the catalyst are responsible for deactivation.In addition,acidity of support affects the formation rate of carbon deposits.Interaction between the active sites and promoters is beneficial for the migration of carbon deposits from the active sites to support surface,and the interaction between active sites and supports could reduce the sintering of active sites. |
