Research Abstract

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.
