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.

Disclosed is a process and plant for producing biocoal in which biogenous starting material located in retorts is pyrolyzed and the flammable pyrolysis gases formed by the pyrolyses are burned to generate hot flue gases. The retorts are introduced consecutively into at least one reactor chamber and by use of the flue gases the pyrolyses are performed therein. The retorts are at least largely closed toward entry of hot flue gases and the heating of the starting materials located in the retorts by the flue gasses is effected only indirectly via the heating of the retorts.
