Abstract: A dry hydrogen production method includes drying sludge; producing a sludge mixture by mixing the dried sludge with an aqueous hydroxide solution and then drying a mixture or mixing the dried sludge with hydroxide powder; introducing the sludge mixture into a reactor; producing a reaction product by heating the sludge mixture in the reactor without supplying water or vapor; separating the reaction product into a gas effluent and a solid effluent through gas-solid separation; and producing a gas product from the gas effluent.

Abstract: The present disclosure relates to a method of generating high-purity hydrogen from waste plastic without producing carbon dioxide. In the method of generating hydrogen according to the embodiments of the present disclosure, reactants include hydroxide, and thus, the amount and purity of the generated hydrogen increases, a reaction temperature suitable for reaching an appropriate hydrogen production rate is lowered, and the amount of generated carbon dioxide is significantly decreased.
