项目摘要

Endothermic reforming characteristics of various hydrocarbons and hydrides were investigated to recover the heat and CO_2 in exhaust gas Ignition characteristics of them and their reforming gases were also investigated.The results were summarized as follows ;The efficient fuel reforming and heat recovery were achieved by catalytic endothermic reaction of various hydrocarbons or hydrides reacting with H_2O or CO_2. The reforming process with H_2O was more efficient and of less carbon formation than with CO_2. H_2 formation ratios and heat recovery ratios increased with increase in reactant concentrations and reaction temperatures. Ratios of heat recovery with endothermic reforming increased up to more than 30%, suggesting a possibility for significant increase in thermal efficiency of heat engines with exhaust heat recovery system including catalytic reformer for hydrocarbon fuel of hydrides fuels.The ignition characteristics of the hydrocarbon or hydrides fuels were almost unchanged by adding their reformed gases to them by less than 5 % on energy basis. The ignition characteristics in NTC area were also unchanged qualitatively by the additions.

研究了各种碳氢化合物和碳氢化合物吸热重整回收废气中的热量和CO_2的特性，并对它们及其重整气的着火特性进行了研究，结果表明：各种碳氢化合物和碳氢化合物通过与H_2O或CO_2的吸热催化反应实现了高效的燃料重整和热量回收。与CO_2相比，H_2O的重整效率更高，生成的碳更少。H_2生成率和热回收率随反应物浓度和反应温度的升高而增大。吸热重整的热回收率提高到30%以上，表明采用含烃类燃料催化重整器的废热回收系统的热机热效率有显著提高的可能性，烃类燃料或烃类燃料的着火特性在重整气加入量小于5%时基本不变。NTC区的着火特性也没有被添加物定性地改变。
