The two-stage gasification of biomass proposed by JIHT RAS is a pyrolysis of biomass, followed by cracking the condensable pyrolysis products on the surface of charcoal to produce synthesis gas. The paper presents the results of experiments designed to produce synthesis gas by the two-stage gasification of wood. The processes of homogeneous and heterogeneous cracking of pyrolysis products on the surface of coal were studied, the optimal parameters of the carbon catalyst for this type of biomass were determined.
