Claim:
1. A process for producing liquid products from a biomass-containing feedstock comprising the steps of: a) devolatilizing the feedstock in a pre-reactor vessel containing hydrogen and a sorbent to produce a pre-reactor vapor stream comprising entrained solid particles; and b) hydropyrolyzing at least a portion of the pre-reactor vapor stream in a hydropyrolysis reactor vessel containing hydrogen and a deoxygenating catalyst, producing a hydropyrolysis reactor output comprising at least one non-condensable gas, a partially deoxygenated hydropyrolysis product and char particles, wherein the sorbent has capacity to adsorb corrosive species, poisons of the deoxygenating catalyst, or a combination thereof.
