Problems solved by technology

On the other hand, the most important problem facing the sulfur industry at present is still the global oversupply. Although short-term or regional shortages occasionally appear, they are not the dominant factor in the global industry, so new sulfur markets need to be opened up

Abstract

The present invention relates to a process for preparing hydrogen gas, and is aimed at providing a technological process capable of combining sulfur-iodine open-circuit circulation and sulfuric aid industry to simultaneously produce hydrogen gas and sulfuric acid and provide electric power and its equipment. Said method includes the following steps: roasting sulfur-bearing mineral, Bunsen reaction, separating HIx phase and H2SO4 phase solution, using electroosmose process to concentrate and purify HIx phase and utilizing HI membrane catalytic decomposition reactor to make decomposition to obtain I2 and find product H2.

Description

technical field [0001] The invention relates to a hydrogen preparation process, in particular to a process and equipment for combined sulfur-iodine open circuit circulation and sulfuric acid industry to co-produce hydrogen, sulfuric acid and electric power. Background technique [0002] In the development of new energy sources in the future, hydrogen energy has attracted widespread attention. Hydrogen energy is one of the most ideal clean energy sources. The only product of its combustion is water, and there is no problem of environmental pollution. At present, fossil fuels are mainly used to produce hydrogen in the world. The reserves of fossil fuels are limited, and this type of hydrogen production system has a large amount of carbon dioxide emissions. Hydrogen production by thermochemical cycle decomposition of water is a more ideal hydrogen production method. This method mainly uses thermal energy to decompose water through a series of chemical reactions to produce hydr...
