METHOD FOR PRODUCING HYDROGEN BY MEANS OF SEGMENTED PYROLYSIS CATALYTIC GASIFICATION OF WOOD WASTE

WIPO Patent Application WO/2023/221783

A1

Disclosed is a method for producing hydrogen by means of segmented pyrolysis catalytic gasification of wood waste, comprising: performing baking pretreatment on the wood waste; performing thermal activation treatment on aluminum smelting waste residues, and mixing the thermally activated aluminum smelting waste residues with the baked wood waste; performing hydrogen production by means of pyrolysis gasification on the mixture to obtain initial pyrolyzed gas and a carbon-aluminum composite material; and taking the obtained carbon-aluminum composite material as a catalyst, and further performing catalytic cracking on the obtained initial pyrolyzed gas. According to the present invention, by means of low-temperature heat treatment, medium-temperature catalytic gasification, and tar steam reforming step-by-step thermochemical conversion of the wood waste, cheap aluminum smelting waste residues are used as a catalyst, pyrolyzed residues catalyze tar steam, the tar yield in a pyrolysis process is reduced, and the hydrogen yield is improved.
