Abstract: Features of the thermal decomposition (pyrolysis, steam reforming) of carbon-containing raw material in the vibro-liquefied bed of inert material and in the presence of the catalysts of deep oxidation were studied. It was shown that the presence of catalysts in wood pyrolysis ensures more complete transformation of condensable organic substances (resins) into light gaseous products (СО, Н2, СО2, СН4). For a model oxygen-containing organic substrate (glycerol), it was shown that the conversion of glycerol during its steam reforming in pseudo-liquefied bed of the catalysts of deep oxidation follows several routes including gasification with the formation of СО, Н2, СО2 and СН4, polycondensation of the products of glycerol dehydration with the formation of coke, steam gasification of coke. Similar processes are realized during the combustion of biomass at the stage of pyrolysis and gasification in the boiling bed. It was shown that efficient catalysts in the steam reforming of glycerol exhibit high activity in the process of oxidation of glycerol and biomass. Investigation of the process of catalytic combustion of aqueous solutions of glycerol showed that the degree of oxidation reaches 99.3–99.9 % with the use of the catalysts of deep oxidation. Oxidation process runs with the highest efficiency in the presence of PK–12–73 catalyst.
