1. A method of producing a hydrogen-enriched product and recovering CO2 in an integrated hydrogen production process and bio-renewable conversion process, the integrated process comprising:
processing a feed stream comprising hydrocarbons or a carbonaceous feedstock in a hydrogen production process unit to produce a synthesis gas mixture comprising hydrogen, carbon dioxide, water, and at least one of methane, carbon monoxide, nitrogen, and argon;
separating an effluent stream from the hydrogen production process unit in a first pressure swing adsorption (PSA) system that produces that produces at least two product streams into at least a first high-pressure hydrogen stream enriched in hydrogen and a hydrogen depleted tail gas stream
compressing the hydrogen depleted tail gas stream in a compressor to form a compressed tail gas stream;
separating the compressed tail gas stream in a CO2 recovery system producing a CO2-enriched product stream and second gas stream comprising hydrogen;
hydrogenating, deoxygenating, isomerizing, and selectively hydrocracking a bio-renewable feedstock in a reaction zone in the presence of hydrogen at reaction conditions by contacting the bio-renewable feedstock with a multifunctional catalyst or a set of catalysts having hydrogenation, deoxygenation, isomerization, and selective hydrocracking functions to provide a reaction effluent comprising paraffinic hydrocarbons, hydrogen, CO2, water, and at least one of methane, ethane, propane, C4+ hydrocarbons, and carbon monoxide;
separating the reaction effluent in a separator into at least a hydrocarbon stream comprising the paraffinic hydrocarbons and an overhead stream comprising hydrogen, CO2, optionally water, and at least one of methane, ethane, propane, C4+ hydrocarbons, and carbon monoxide;
separating the hydrocarbon stream in a fractionation zone to generate a hydrocarbon product stream, wherein the hydrocarbon product stream comprises at least one of a diesel stream comprising hydrocarbons having boiling points in a diesel boiling point range, an aviation fuel stream having hydrocarbons having boiling points in an aviation fuel boiling point range, and a naphtha stream having hydrocarbons in a naphtha boiling point range;
recovering the hydrocarbon product stream;
separating the overhead stream from the separator into at least a hydrogen stream comprising hydrogen; and
introducing at least a portion of a purge gas stream comprising hydrogen from the hydrogen stream from the bio-renewable conversion process into a process unit in the hydrogen production process.
