  • Process for producing synthetic hydrocarbons from biomass
    Patent number: 11753597
    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.
    Type: Grant
