Abstract

The invention provides a low-cost, high-benefit and environment-friendly method for hydrogen production by coupling and catalytic reforming of chemical chains and a device thereof. The method couples the chemical circulation process that a carbon dioxide absorbent absorbs and releases carbon dioxide and the reaction process that a hydrogen-containing substance produces hydrogen by catalytic reforming to realize the regeneration and recovery of a catalyst and the carbon dioxide absorbent and realize the hydrogen production process with low cost, high benefit, and environmental protection through a catalyst regeneration device and an absorbent calcination decomposition device.

Description

technical field [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a method and device for hydrogen production by chemical chain coupling catalytic reforming. technical background [0002] As an efficient and clean secondary energy source, hydrogen has attracted more and more attention, and has been widely used in many industries. The expansion from the aerospace field in the past to today's civilian industry, especially the use of fuel cells, has brought good economic prospects and environmental protection advantages to the efficient and clean utilization of hydrogen energy, and has also promoted people's widespread attention to hydrogen energy. At present, mature hydrogen production technologies include coal gasification, partial oxidation of oil, biomass synthesis gas, solar thermochemistry, electrolysis of water and methane-steam reforming, etc. Among them, the cost of coal gasification, partial oxidation of oil, ...
