  • Process for producing jet fuel from a hydrocarbon synthesis product stream
    Patent number: 9879192
    Abstract: A process for producing jet fuel comprising the following steps: A.1) separating at least a portion of the C9 to C15 fraction from the product of a hydrocarbon synthesis process; A.2) converting at least a part of the separated C9 to C15 fraction to aromatic hydrocarbons; A.3) obtaining a jet fuel comprising the, optionally further treated, converted separated C9 to C15 fraction of step A.2); B.1) separating at least a portion of the C16+ fraction from the product of a hydrocarbon synthesis process; B.2) reducing the average number of carbon atoms of at least a portion of the separated C16+ fraction; B.3) optionally, separating the C9 to C15 fraction of at least a portion from the product obtained from step B.2); and B.4) adding at least a portion of the C9 to C15 fraction separated in step B.3), if present; or at least a portion of the product of step B.2).

  • Process for the conversion of a feed containing biomass for the production of hydrocarbons, by Fischer-Tropsch synthesis
    Patent number: 9422492
    Abstract: The present invention concerns an integrated process for the production of liquid hydrocarbons starting from a feed containing at least one fraction of biomass and optionally at least one fraction of another feed, said process comprising at least one pre-treatment step, a gasification step, a step for conditioning synthesis gas, a water scrubbing step, a step for eliminating acid gases, a final purification step, and a catalytic Fischer-Tropsch synthesis reaction step.
