Abstract: The present disclosure relates to a device for multi-system biomass and coal co-combustion to prepare a graphite sample. The device includes an oxygen cylinder, a tubular furnace, a transition assembly, a flue gas filter, an impurity gas absorption assembly, a transfer assembly, a raw sample oxidation assembly, and a vacuum pump. The oxygen cylinder is configured to provide oxygen for a combustion reaction. The tubular furnace is configured to provide heat for the combustion reaction. The transition assembly is configured to cool combustion flue gas. The flue gas filter is configured to remove particulate impurities from the combustion flue gas. The impurity gas absorption assembly is configured to remove impurity gas from the combustion flue gas. The transfer assembly is configured to remove moisture and the impurity gas from the combustion flue gas.

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.
