  • Publication number: 20240059979
    Abstract: The present invention provides a process for producing one or more of hydrocarbon products from a renewable feedstock comprising triglycerides, free fatty acids or combinations thereof. The process may comprise the steps of mixing the renewable feedstock with a diluent to form a diluted feedstock; supplying or providing hydrogen gas to the diluted feedstock so that the hydrogen gas may dissolve in the diluted feedstock to form a diluted feedstock enriched with dissolved hydrogen; and feeding the diluted feedstock enriched with dissolved hydrogen to at least a reactor having at least a reaction zone comprising at least a catalyst bed under predefined conditions, thereby producing a reaction effluent which can be further processed (e.g. by using one or more distillation units and one or more adsorption units) to form one or more of hydrocarbon products.

  • Patent number: 11674096
    Abstract: A system for processing a renewable bio-based material comprising: a reactor, a feedstock substantially renewable and comprising triglycerides and free fatty acids, with hydrogen in the presence of a catalyst in a reactor to form a treated oil; a heat exchanger for receiving the treated oil from the reactor and reducing its temperature to a predetermined temperature; a high-pressure separator followed by a low-pressure separator; and (i) a distillation unit for passing the treated oil through to form green diesel and an adsorption unit for passing the green diesel through; or (ii) at least one distillation column to separate the treated oil into at least one component and an adsorption column for passing the at least one component through; wherein the reactor comprises a cooling function for controlling the temperature of the reactor; wherein the cooling function is an internal cooling function comprising adding a cooling substance into the reactor.

  • Publication number: 20210054292
    Abstract: The present invention relates to a method for processing a renewable bio-based material comprising the step of reacting the bio-based material with hydrogen in the presence of a catalyst on a support in a reactor to form a treated oil; (i) passing the treated oil through a distillation unit and an adsorption unit to form green diesel; and/or (ii) passing the treated oil through at least one distillation column to separate the treated oil into at least one component and passing the at least one component through an adsorption column; and wherein the reactor comprises a cooling function for controlling the temperature of the reactor, wherein the cooling function is at least one of an internal cooling function and an external cooling function.
