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.
Claims19
A method of generating hydrogen using plastic containing oxygen, comprising:
- subjecting the plastic containing oxygen to a thermal treatment reaction with hydroxide and water vapor to obtain hydrogen,
- wherein an amount of generated CO2 is 10 mol % or less of the total generated gas.
A method of generating hydrogen using plastic not containing oxygen, comprising:
- thermally oxidizing the plastic not containing oxygen to obtain thermally oxidized plastic;
- and
- subjecting the thermally oxidized plastic to a thermal treatment reaction with hydroxide and water vapor to obtain hydrogen.
