摘　　要：催化燃烧技术的工业应用涵盖了我国“十四五”规划和2035远景目标纲要中指定的若干未来战略性产业,因此具有重要的科学和战略意义。在许多催化燃烧的应用场景中,气相火焰被点燃并与催化反应路径发生错综复杂的耦合关系。本文回顾了近年来贵金属催化通道内预混层流火焰的最新研究进展,简要梳理了催化通道内催化气相燃烧的控制方程、数值模型、点火和传递条件,以及氢气、合成气、甲烷、丙烷、正癸烷等重要燃料在铂、铑、钯等催化通道内的贫燃和富燃燃烧时的火焰形态和特性,尤其是化学、流动和传热传质等方面的决定因素。The applications of catalytic combustion technology cover a number of future strategic industries and therefore are of interests to both fundamental and applied combustion research.In many catalytic combustion processes,gas phase fames are ignited and intricately coupled with the catalytic reaction pathway.This article briefy reviews the latest research progress on premixed laminar combustion in catalytic channels coated with commonly used noble metals,including the controlling equations,numerical models,and conditions of flame ignition and propagation during coupled catalytic-gaseous combustion in microchannels.Several key fuels were reviewed,including hydrogen,syngas,methane,propane,n-decane,etc.Moreover,their distinct fame shapes,propensities of both fuel-lean and fuel-rich flames,and especially the determining factors of chemistry,flow and heat and mass transfer were discussed.
