Normal-temperature water catalysis hydrogen production method and equipment

Abstract

The technical problem to be solved by the invention is how to fully utilize an external heat source to produce hydrogen. The normal-temperature water catalysis hydrogen production method comprises the steps of (1) continuously heating a pyroelectric catalysis piece at the heating temperature not exceeding the boiling temperature of water; (2) in the continuous heating process of the pyroelectric catalysis piece, spraying normal-temperature water to the pyroelectric catalysis piece so as to enable different parts on the pyroelectric catalysis piece to generate temperature difference and thermal fluctuation, and enabling water making contact with the pyroelectric catalysis piece to be dissociated to generate H2; and 3) collecting H2 generated in the step 2). The pyroelectric catalysis piece is a structure made of pyroelectric negative ion particles. According to the hydrogen production method, most of heat sources can be utilized for hydrogen production, and the hydrogen production method is an environment-friendly and low-cost energy scheme. The invention also provides hydrogen production equipment for implementing the hydrogen production method. The hydrogen production equipment has the advantages of simple and reliable structure, low manufacturing cost and hydrogen production cost, easiness in wide installation and use and the like.

technical field

[0001] The invention relates to a method for catalytic hydrogen production by normal temperature water and a hydrogen production equipment implementing the method. Background technique

[0002] The Chinese invention patent 201210175876.0 entitled "Method and Equipment for Water Catalytic Hydrogen Production and Power Generation" discloses a hydrogen production method and equipment. The hydrogen production method and equipment need to heat water into water vapor, and allow a large amount of water vapor to enter the water decomposition container to react with negative ion powder in the water decomposition container to generate hydrogen. However, heating water into steam requires energy. Although it has been mentioned in the literature that industrial waste heat, solar energy and geothermal heat sources can be used to heat water into water vapor, if these external heat sources are not enough to heat water into water vapor, Then the hydrogen production efficienc...
