A process for producing fuel from biomass is disclosed herein. The process includes torrefying biomass material at a temperature between 80° C. to 400° C. to form particulated biomass having a mean average particle size between 1 μm and 1000 μm. The particulated biomass is mixed with a liquid hydrocarbon to form a suspension, wherein the suspension includes from 1 weight percent to 40 weight percent particulated biomass. The suspension is fed into a unit selected from the group consisting of a pyrolysis reactor, a fluid catalytic cracking unit, a delayed coker, a fluid coker, a hydroprocessing unit, and a hydrocracking unit, and then at least a portion of the particulated biomass of the suspension is converted into fuel.
