METHOD OF CATALYTIC GASIFICATION OF BIOMASS WITH OBTAINING GASEOUS FUELS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to field of application of renewable sources of raw material - biomass. Claimed is method of catalytic gasification of biomass with obtaining gaseous fuels. Method includes milling biomass and its thermal processing in air medium at 600÷800°C and pressure 1.2-2.0 atm, catalytic thermal degradation of gaseous products in presence of transition metals, method differs by the fact that catalytic thermal degradation is realised at temperature 500÷550°C, weight ratio of catalyst and biomass is 0.01÷0.05 and air consumption 1.0÷2.5 m³ per 1 kg of biomass, and as catalyst is applied mixture of oxides of chrome and vanadium, applied on natural aluminosilicate in quantity 1÷20 wt % and 1÷5 wt % respectively, or as catalyst applied is mixture of oxides of molybdenum and manganese, applied on natural aluminosilicate in quantity 1÷10 wt % and 10÷30 wt % respectively, or as catalyst applied is mixture of cobalt and nickel oxides, applied on natural aluminosilicate in quantity 5÷25 wt % and 1÷40 wt % respectively.;EFFECT: increased output of flammable hydrocarbons, achievement of good efficiency of gasification.;6 tbl, 6 ex
