Method for producing hydrogen

Abstract

The method relates to a method for producing hydrogen, which comprises a hydrogen producing reaction forming step, a hydrogen producing reaction accelerating step and a derivation treating step, wherein in one of the viable method of the hydrogen producing reaction forming step, metal, metal alloy or waste materials thereof are used as reaction materials for producing hydrogen, and the hydrogen and by-products are obtained after cleaning treatment and chemical reaction by in contact with electrolyte; in one of the viable method of the hydrogen producing reaction accelerating step, organic acid or inorganic acid are added in the hydrogen producing reaction forming step so as to improve the hydrogen producing rate by the chemical reaction; in the derivation treating step, the electrolyte containing metal ion after the hydrogen producing reaction is finished is dried and properly treated or reduced by an electrolytic process so that the economical and practical purposes of oxidation reduction cycle can be achieved and no secondary pollution is caused.

Description

technical field [0001] The present invention relates to a hydrogen production method, in particular to a hydrogen production method that can provide a better hydrogen production rate by chemical reaction or both chemical reaction and electrochemical reaction. Background technique [0002] Hydrogen is a non-polluting energy source. In addition to being used as a fuel and a raw material for nickel-metal hydride batteries, it can also be used as an industrial energy source, such as: desulfurization reaction materials in petroleum processing and chemical industry, metallurgy industry and semiconductor industry. . Moreover, the reaction of hydrogen in the fuel cell will not produce carbon dioxide. In the development of fuel cells, hydrogen is expected to become a source of new energy, and its demand will double. Therefore, for the future application of hydrogen Not one of the primary research topics. [0003] As we all know, although hydrogen exists in the earth's crust under c...

However, the sodium borohydride in this method must be extracted from borate ore, and the cost of extracting one kilogram of sodium borohydride is about 80 US dollars at present, and the borate ore in the world is only concentrated in a few countries (such as the U.S. and Turkey), in addition to being difficult to obtain, the high cost is not in line with economic benefits

[0005] In addition, there are still methods of using metal waste to produce renewable hydrogen energy, for example: the related research on recycling waste aluminum cans as hydrogen production materials, but the coated plastic on the surface of recycled aluminum cans still needs to be washed off with sulfuric acid solution, so it is relatively Derived from the problem of industrial wastewater treatment, resulting in secondary pollution
