A hybrid bio-thermal liquefaction process for improved carbonaceous liquefaction to produce alcohol containing fuels wherein an organic carbonaceous feed is subjected to active fermentation producing alcohol containing liquid fuel product and fermentation residue, the fermentation residue being introduced into a thermochemical converter and at least a substantial portion of the organic carbon component of the residue converted under elevated temperature conditions producing thermochemical converter products and thermochemical residue with a portion of at least one of the thermochemical products or their derivatives, or thermochemical residue being passed to the fermentation reactor. The process provides high overall process energy efficiencies and utilizes the total agricultural biomass crop thereby greatly reducing waste disposal problems. The alcohol content (ethanolmethanol) of the liquid fuels produced can be increased by utilization of embodiments of the process emphasizing thermochemical gas production followed by catalytic synthesis while the fuel oil and gasoline content of the liquid fuels produced can be increased by embodiments of the process emphasizing thermochemical liquefaction.
