Abstract

An experiment and the examination were carried out in order to elucidate the optimum conditions in the falling liquid film reaction method, in the conversion of solar energy using the decomposition reaction of 2-propanol. The device for the experiment was constituted of a reaction container, tubular pump, cooling pipe, sampling container for effluent from the upper and lower part of the reaction container, and gas burette. Examined in the experiment were various factors such as a fibrous activated carbon (catalyst support), ratio for carrying catalyst, catalytic composition and heating temperature. In the experiment, with the temperature inside the reaction container fully stabilized under prescribed conditions, measurement was done for the hydrogen generation by the gas burette for 10 minutes as well as for the sampling of effluent. The experiment revealed that the heat utilization ratio reached the maximum of about 27% when the heating temperature was 90{degree}C using a catalyst with the ratio of RU and Pt 1 to 1 and the ratio for carrying catalyst 10wt%, so that a great improvement was obtained in the heat utilization ratio at a low temperature. Also obtained was a large inversion ratio of about 15%. 4 refs., 6 figs., 5 tabs.
