Tohoku University Technology: Hydrogen gas production method and equipment: T15-157
No need of pulverization process! Able to product easily the hydrogen gas at low cost!
Conventional method of producing hydrogen gas from organic matters such as biomass or plastics, is composed of mixing calcium hydroxide and nickel hydroxide, applying mechanochemical processing (grinding), and then heating. However, since the pulverization process requires energy and equipment, technology development with further cost reduction was expected. This invention is about a method of producing hydrogen gas from organic materials such as biomass and plastics at low cost without requiring a grinding process. Organic materials such as biomass and plastics are pyrolyzed in a lumpy state to generate pyrolysis gas, and then this gas is heated with an aqueous solution containing nickel to generate hydrogen gas. In addition, the nickel added during heating can be recovered and reused.
