Part of CO-rich syngas, including volatile metal or any acid impurities, reacts with water making cleaned, heated, H.sub.2 -enriched syngas. The rest of the impure CO-rich syngas is combined with hot, H.sub.2 -enriched syngas making cleaned, H.sub.2 -rich syngas, useful for making methanol or oxo co ...

Paul S Wallace, Kay A Johnson, Janice L Kasbaum, Alma I Rodarte: Recycle of hydrogen from hydroprocessing purge gas. Texaco, Cantor Colburn, February 28, 2006: US07004985 (32 worldwide citation)

The present invention relates to an integrated gasification and hydroprocessing process. A hydrocarbonaceous fuel is first gasified to produce syngas, and then a portion of the hydrogen is removed from the syngas. The hydrogen is compressed and used as an excess reactant in a hydroprocessing unit. H ...
