Abstract: A staged pyrolysis-catalytic gasification process for hydrogen production from biomass waste is provided, including: drying and crushing the biomass waste to obtain crushed biomass waste; continuously adding the crushed biomass waste as feed material into a cascading pyrolysis device to obtain semi-coke and volatile matter, periodically discharging the semi-coke from a bottom of the cascading pyrolysis device, and filtering the volatile matter through the semi-coke accumulated in a catalytic conversion section to remove fly ash to obtain high temperature pyrolysis gas; continuously introducing the high temperature pyrolysis gas into a first atmospheric catalytic converter to cause that tar in the high temperature pyrolysis gas undergoes catalytic cracking to obtain hydrogen-rich fuel gas; and continuously introducing the hydrogen-rich fuel gas into a second atmospheric catalytic converter to cause that alkane gas in the hydrogen-rich fuel gas undergoes catalytic cracking to produce hydrogen.

Abstract: Disclosed in the present disclosure is a method for producing hydrogen from woody waste through staged pyrolysis and catalytic gasification. The method includes: performing baking pretreatment on the woody waste; thermally activating aluminum smelting waste residues, and mixing the thermally activated aluminum smelting waste residues with the baked woody waste; pyrolyzing and gasifying the mixture for hydrogen production to obtain primary pyrolysis gas and a carbon-aluminum composite material; and further catalytically cracking the obtained primary pyrolysis gas by taking the obtained carbon-aluminum composite material as a catalyst.
