IPC: C10J3/60
Filed: 2022-10-07
Abstract: To provide a solution to the problem that an apparatus for producing pure hydrogen from biomass and coal is complicated and causes cost increase, by a system that involves the formation of aqueous gas usable as a gas turbine fuel with improved efficiency even when the hydrogen purity is not high or even when the combustion heat is low due to the presence of carbon dioxide or carbon monoxide in the gas.SOLUTION: A hydrogen generator is provided which has multiple furnaces each combining a heating furnace and a carbonization/aqueous gas formation furnace side by side. Biomass and coal are carbonized in the presence of an aqueous gas formation catalyst, and thereafter steam is supplied to carry out an aqueous gas formation reaction. The reaction time can be shortened and furthermore aqueous gas, with carbon monoxide or carbon dioxide contained therein, can be used for gas turbine power generation, which leads to cost reduction. The formation of aqueous gas containing hydrogen and carbon dioxide as main components is also possible, and high-purity hydrogen can be easily obtained only by separating carbon dioxide. In addition, the formation of aqueous gas containing carbon monoxide and hydrogen as main components is also possible, which reduces the cost of methanol synthesis.SELECTED DRAWING: Figure 1
