摘　　要：介绍了超绝热燃烧技术的特点及其实现机理,对H_2S分解进行了热力学分析,综述了H_2S超绝热分解制氢的最新进展。评述了该技术的优越性在不使用催化剂和外加热源情况下,利用H2S在多孔介质中超绝热部分氧化分解,在脱除H2S的同时可以回收硫和氢,显著降低污染排放。利用该技术可以处理含有毒有害成分的工业废气。Due to evidently increasing burning temperature,extending combustible limit and ~obviously reducing pollutant emission and etc,superadiabatic combustion in inert porous medium can be used to treat some waste gases which contain combustible components.In addition to the recovery of elemental sulfur,hydrogen can be obtained by superadiabatic decomposition of H_2S without catalyst and external heating.The present paper introduces the characteristics and ~mechanism of superadiabatic combustion in porous media,and summarizes the advances in H_2S ~super adiabatic decomposition.Thermodynamic analysis of superadiabatic decomposition of H_2S is carried out and the advantages of the novel process over conventional Claus process are ~also ~discussed .The analysis and reviews indicate high potential of the technology in treating waste gases and environmental protection.
