Abstract
Effects of various hydrocarbons reforming on heat and (CO)_2 recovery were investigated to obtain fundamental data for improving thermal efficiency of heat engines. Among various reforming processes, methane-(CO)_2,and methane-H_2O reforming showed comparatively high heat recovery effect, attaining heat recovery ratios up to 30% or more although the heat recovery ratios depended on temperature, ratio of hydrocarbon and (CO)_2 or H_2O, with or without catalyst, and others. Ignition lag characteristics were also investigated for mixtures of base hydrocarbon fuels and reformed gas products. A significant change in ignition lags was not recognized for the mixtures of base fuel and reformed products up to 50%.
