摘　　要：简要介绍了天然气高温催化燃烧的特征与机理,分别从催化剂的高温烧结、活性组分的迁移和流失、中毒、催化剂活性组分与载体的强相互作用、高温热震等引起的催化剂失活.概述了各种典型催化剂的高温失活机理,并对制备高温稳定的活泼催化剂提出了建议。The characteristics and mechanism of catalytic combustion of natural gas at high temperatures was briefly introduced. The deactivation mechanism of some typical catalysts from such aspects as sinter at high temperature, e-vaporation, poisoning and transportation of active compositions in catalyst phases, strong interaction between supports and active components, and the thermal shocks during high temperature catalytic combustion reaction were reviewed. Some advice was given for preparing stable active catalysts for catalytic combustion at high temperature.
