沸騰・液膜条件下での2-プロパノール脱水素触媒反応の特質

抄録

In order to improve the thermal efficiency of 2-propanol /acetone /hydrogen chemical heat pump system, enhancements of the conversion for 2-propanol dehydrogenation with carbon-supported metal catalysis in liquid-film states were investigated. The amount ratio of solid catalyst to liquid substrate was an important factor, because not only the rates of hydrogen evolution but also the total conversions were influenced sensitively and tremendously under boiling and refluxing conditions. The equilibrium conversion of 12.7% at 90°C was surpassed easily as the consequence of reactive distillation and nonequilibrium nature of liquid-film conditions for catalytic 2-propanol dehydrogenation.
