US 2022/0017825 A1 · METHOD FOR PREPARING BIOCHAR AND HYDROGEN BY UTILIZING ANAEROBIC FERMENTATION BYPRODUCTS

Abstract

A method for preparing biochar and hydrogen by utilizing anaerobic fermentation byproducts, the method including: (1) mixing a first straw, seeding sludge and distilled water, and then carrying out anaerobic fermentation to obtain a mixed product after fermentation; (2) performing separation on the mixed product to obtain a second straw and biogas slurry; and (3) carbonizing the second straw to obtain biochar, and collecting gas after a pressurized catalytic reaction on the biogas slurry to obtain hydrogen.
