    Abstract: A process for preparing synthetic hydrocarbons from a biomass feedstock is provided. The process involves electrolyzing water in an electrolyzer to produce oxygen and hydrogen, using the generated oxygen to gasify a biomass feedstock under partial oxidation reaction conditions to generate a hydrogen lean syngas, adding at least a portion of the generated hydrogen to the hydrogen lean syngas to formulate hydrogen rich syngas, which is reacted a Fischer Tropsch (FT) reactor to produce the synthetic hydrocarbons and water. At least a portion of the water produced in the FT reaction is recycled for use in the electrolysis step, and optionally using heat generated from the FT reaction to dry the biomass feedstock.

    Abstract: A process for preparing synthetic hydrocarbons from a biomass feedstock is provided. The process involves electrolysis of steam and/or CO2, optionally along with a refinery gas in a high temperature co-electrolyzer (HTCE) to produce oxygen and hydrogen and/or enhanced hydrogen rich syngas. The oxygen generated via the electrolysis process is used for partial oxidation of a biomass feedstock in a gasifier to generate a hydrogen lean syngas. The hydrogen lean syngas is mixed with at least a portion of the hydrogen and/or enhanced hydrogen rich syngas generated via the high temperature electrolysis/co-electrolysis to formulate a hydrogen rich syngas. The hydrogen rich syngas is then reacted in a Fischer Tropsch (FT) reactor to produce synthetic hydrocarbons and refinery gas.
