NOVELTY - Processing (M1) biomass (611) into hydrocarbon fuels, comprises: processing biomass in hydropyrolysis reactor resulting in hydrocarbon fuels, char (613), and process vapor stream; cooling process vapor stream to condensation temperature resulting in aqueous stream; sending aqueous stream to catalytic reactor; injecting air (641) into catalytic reactor to obtain aqueous product stream having ammonia and ammonium sulfate; and obtaining cooled product vapor stream containing non-condensable process vapors having hydrogen, methane, carbon mono oxide, carbon dioxide, ammonia and hydrogen sulfide.    USE - The method is useful for: processing biomass into hydrocarbon fuels; and removing sulfur from biomass conversion products (claimed).    ADVANTAGE - The method: provides char and ammonium sulfate that are combined to produce mixture that is utilized as agricultural fertilizer product, as a powder, granulated or pelletized material to improve quality of soil for use as agricultural substrate and provides fertilizing component for the sustenance of lignocellulosic biomass; and provides char which is essentially inert carbonaceous material and free of hydrocarbon contaminants that are toxic to humans or plants.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for removing (M2) sulfur from biomass conversion products, comprising processing the biomass in the hydropyrolysis reactor, resulting in char and a heated process vapor stream containing hydrogen, water vapor, condensable hydrocarbon vapors, non-condensable hydrocarbon vapors, carbon monoxide and carbon dioxide, cooling the process vapor stream to a condensation temperature to a cooled and condensed product stream, separating the cooled and condensed product stream into a gaseous and liquid component, obtaining a liquid hydrocarbon stream, obtaining an aqueous stream, containing water (612), ammonia, and ammonium sulfide, obtaining the cooled product vapor stream, sending the aqueous stream to a catalytic reactor, injecting air into the catalytic reactor thus oxidizing ammonium sulfide over a catalyst resulting in ammonium sulfate, obtaining an aqueous product stream containing water, ammonia and ammonium sulfate, evaporating excess water from the aqueous product stream containing ammonium sulfate resulting in steam and a concentrate of ammonium sulfate, cooling the concentrate of ammonium sulfate to precipitate out the ammonium sulfate as crystallized ammonium sulfate and filtering out the crystallized ammonium sulfate.    DESCRIPTION OF DRAWING(S) - The figure shows a process flow diagram for processing biomass into hydrocarbon fuels, which incorporates both an hydrogen sulfide removal unit, associated with the cooled vapor product stream, and a sour-water stripper upstream of the oxidation reactor.
