Integrated hydrogen production and bio-renewable conversion process

A method of producing a hydrogen-enriched product and recovering CO2 from a hydrogen production process unit 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 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 a second gas stream comprising hydrogen;
• and
• introducing at least a portion of a purge gas stream comprising hydrogen from a bio-renewable conversion process for making a hydrocarbon product from a bio-renewable feedstock into a process unit used in the method of producing hydrogen and recovering CO2.
