摘　　要：为了解决重整器吸热的问题,将催化燃烧反应耦合在反应器内,重整反应的热量由燃烧反应供给,这种耦合反应器可以提高系统热效率。但是由于两种反应的化学反应速率不同,吸放热反应的匹配程度影响着制氢效率。加强过程耦合,研究催化燃烧腔与重整腔之间热量匹配才能制造出结构紧凑、能效高的集成反应器。针对这个问题,本文展开了相关实验研究,探究了两个反应腔在不同的流动方向以及催化燃烧腔不同的壁面涂覆方式下最佳的耦合方案,结果表明:无论选用哪种集成方式,应保证重整器前段的温度高,壁面温度均匀;其中,垂直布置方式具有较大的优势,产氢含量可以达到74%以上;当催化燃烧腔使用泡沫金属作为催化剂载体时产氢含量可以达到60%以上。To solve the problem of heat absorption in the reformer,the coupled catalytic combustion reaction is in the reactor.The heat of reforming reaction is supplied by the combustion reaction.This coupled reactor can improve the thermal efficiency of the system,but the degree of matching of heat absorption and emission reactions affects the efficiency of hydrogen production because the chemical reaction rates of the two reactions are different.To enhance the process coupling,the heat matching between the catalytic combustion chamber and the reforming chamber can be studied in order to produce a compact and energy-efficient integrated reactor.To address this issue,this paper conducted an experimental study to investigate the best coupling between the two reactor chambers under different flow directions and different wall coating methods of the catalytic combustion chamber.The results show that no matter which integration method is chosen,the temperature in the front section of the reformer should be high and the wall temperature should be uniform;among them,the vertical arrangement has a greater advantage and the hydrogen production content can reach more than 74%;when the catalytic combustion chamber uses foam metal as the catalyst carrier the hydrogen production content can reach more than 60%.
