NOVELTY - System (S1) comprises: a digester (106) that receives a biomass feedstock (102) and a digestive solvent (110) operating under conditions to remove nitrogen and sulfur compounds from feedstock, and discharges treated stream comprising carbohydrate having less than 35% of the sulfur content and less than 35% of the nitrogen content based on untreated biomass feedstock on a dry mass basis; an aqueous phase reforming reactor (126) comprising an aqueous phase reforming catalyst that receives the treated stream and discharges an oxygenated intermediate stream (130); and a fuels processing reactor.    USE - The system is useful for producing a liquid fuel from biomass (claimed), where the liquid fuel is useful as transportation fuel, jet fuel or diesel fuel.    ADVANTAGE - The system: facilitates the recycling of oxygenated intermediates, hence it is cost effective; avoids the occurrence of a separate hydrogenation reaction section; can be operated at lower temperatures, hence minimizes heavy ends byproduct formation and coke formation; forms the hydrocarbon product having low levels of olefins, aromatics or alcohols; and provides the fuel with high yield.    DETAILED DESCRIPTION - System (S1) comprises: a digester (106) that receives a biomass feedstock (102) and a digestive solvent (110) operating under conditions to remove nitrogen compounds and sulfur compounds from the biomass feedstock, and discharges a treated stream comprising a carbohydrate having less than 35% of the sulfur content and less than 35% of the nitrogen content based on untreated biomass feedstock on a dry mass basis; an aqueous phase reforming reactor (126) comprising an aqueous phase reforming catalyst that receives the treated stream and discharges an oxygenated intermediate stream (130), where a first portion of the oxygenated intermediate stream is recycled to the digester as at least a portion of the digestive solvent; and a fuels processing reactor comprising a condensation catalyst that receives a second portion of the oxygenated intermediate stream and discharges a liquid fuel. An INDEPENDENT CLAIM is also included for a system (S2) comprising: the digester that operates under conditions to remove nitrogen, phosphorus and sulfur compounds from the biomass feedstock and discharges the treated stream comprising the carbohydrate having less than 35% of the sulfur content and less than 35% of the nitrogen content based on untreated biomass feedstock on a dry mass basis; the aqueous phase reforming reactor comprising the aqueous phase reforming catalyst; a first fuels processing reactor comprising a dehydrogenation catalyst that receives a second portion of the oxygenated intermediate stream and discharges an olefin-containing stream; and a second fuels processing reactor comprising an alkylation catalyst that receives the olefin-containing stream and discharges a liquid fuel.
