Pyrolysis of wood in vibro-fluidized beds of disperse packings of deep oxidation catalysts and inert materials is investigated. It is shown that the properties of the disperse packing material of vibro-fluidized beds do not have a significant effect on the rate and degree of conversion of wood to volatiles. The presence of catalysts in the vibro-fluidized bed leads to an increase in the amount of CO2, CO, H2, and CH4 in the gas phase compared to the pyrolysis of wood in vibro-fluidized beds of inert materials. The greatest activity in the conversion of volatiles to CO2, CO, H2, CH4 was found for the catalyst IK-12-73 (Mg0.5Cu0.5Cr2O4/Al2O3). The accumulation of carbon in IK-12–73 catalyst has little effect on the conversion of volatile substances to gaseous products. The degree of burnout of wood particles under conditions of a vibro-fluidized bed of IK-12-73 catalyst is 99.7%, which is consistent with data on the catalytic combustion of wood in the fluidized bed.
