NOVELTY - Method of high purity hydrogen recovery from syngas from gasifier (304), comprises: providing syngas stream from gasifier to first hydrogen separation device (314) to produce first high purity hydrogen stream and tail gas stream; increasing pressure of tail gas stream in first compressor to produce pressurized tail gas stream; providing pressurized tail gas stream to second hydrogen separation device (316) to produce second high purity hydrogen stream and residue stream; and combining first and second high purity hydrogen product streams to produce high purity hydrogen product stream.    USE - The method is useful for recovering high purity hydrogen from syngas from refinery residual fuels including petroleum coke, visbreaker tar, pitch from deasphalting processes, vacuum residues and atmospheric residues, and biomass including agricultural waste, biodegradable wastes, municipal solid waste, sugar crop waste and starch crop waste (all claimed).    DETAILED DESCRIPTION - Method of high hydrogen recovery from syngas from a gasifier (304), comprises: providing a syngas stream from the gasifier to first hydrogen separation device (314) to produce a first high purity hydrogen stream and a tail gas stream, where the first hydrogen separation device is a pressure swing adsorption device; increasing the pressure of the tail gas stream in a first compressor to produce a pressurized tail gas stream; providing the pressurized tail gas stream to a second hydrogen separation device (316) to produce a second high purity hydrogen stream and a residue stream; and combining the first high purity hydrogen product stream and the second high purity hydrogen product stream to produce a high purity hydrogen product stream.    DESCRIPTION OF DRAWING(S) - The figure shows the method of high hydrogen recovery from syngas, utilizing pressure swing adsorption.
