  • Publication number: 20230295526
    Abstract: The present invention relates to a process and plant for producing hydrocarbon product boiling in the gasoline boiling range from a feedstock originating from a renewable source, the process and plant comprising a hydroprocessing stage which includes hydrodoxygenation for producing renewable diesel and renewable naphtha, and subsequent aromatization of the renewable naphtha thereby also producing a lighthydrocarbon gas stream, such as liquid petroleum gas (LPG), from which a hydrogen stream is produced.

  • Patent number: 10752842
    Abstract: The present disclosure refers to a process and a process plant for extraction of metals from a hydrocarbon mixture obtained from a gasification or pyrolysis process, comprising the steps of combining said hydrocarbon mixture with an aqueous acid forming a mixture, mixing said mixture, separating said mixture in a contaminated aqueous phase and a purified hydrocarbon phase, with the associated benefit of said aqueous acid being able to release metals bound in such gasification and pyrolysis processes.

  • Publication number: 20170240820
    Abstract: A broad embodiment of the present disclosure relates to a process for removal of at least 20%, 40% or 80% of the aromatics content of the fraction boiling above 190° C. from a heavy hydrocarbonaceous feedstock comprising at least 30 wt % aromatics, at least 3000 wt ppm nitrogen and at least 0.5 wt % oxygen said method being carried out in a single stage in which no intermediate stream is withdrawn and comprising the steps of a. providing a hydrotreater feed by combining said heavy hydrocarbonaceous feedstock with excess hydrogen, providing a hydrotreater feed, b. providing a hydrotreated hydrocarbon product comprising less than 30 wt ppm nitrogen, less than 20 wt ppm nitrogen or less than 10 wt ppm nitrogen by hydrotreating said hydrotreater feed by contacting it with a material catalytically active in hydrotreatment under hydrotreatment conditions, c.
