HEAT RECOVERY AND HEAT UTILIZATION USING CHEMICAL ENERGY OF METHANOL AND METHYL FORMATE, AND METHOD FOR GENERATING POWER

摘要

PROBLEM TO BE SOLVED: To provide a method efficiently recovering heat and enhancing the utilization of heat from the standpoint of a device cost and an operation cost in a conversion system of heat energy and chemical energy using the decomposition reaction of methanol and methyl formate and the synthetic reaction of methanol and methyl formate. SOLUTION: Heat is recovered by liquid phase decomposition reaction (endothermic reaction) of methanol and methyl formate, then power is generated with an expansion turbine by using decomposition product gas, and heat of liquid phase synthetic reaction of methanol and methyl formate (exothermic reaction) is utilized.
