1. A process for treating high sulfur Heavy Marine Fuel Oil for use as feedstock in a subsequent refinery unit, the process comprising:

  • mixing a quantity of Feedstock Heavy Marine Fuel Oil with a quantity of Activating Gas mixture to give a Feedstock Mixture;

    contacting the Feedstock Mixture with one or more catalysts under reactive conditions to form a Process Mixture from said Feedstock Mixture;

    receiving said Process Mixture and separating hydrocarbon liquid components of the Process Mixture from any bulk gaseous components of the Process Mixture;

    subsequently separating any residual gaseous components and any by-product hydrocarbon components from the hydrocarbon liquid components to give a Product Heavy Marine Fuel Oil; and

    , discharging the Product Heavy Marine Fuel Oil, wherein the Feedstock Heavy Marine Fuel Oil complies with ISO 8217 (2017) and has a sulfur content (ISO 14596 or ISO

         8754) between the range of 5.0 mass % to 1.0 mass %, and wherein said Feedstock Heavy Marine Fuel Oil has;

    a maximum of kinematic viscosity at 50°

    C. (ISO

         3104) between the range from 180 mm2/s to 700 mm2/s;

    a maximum of density at 15°

    C. (ISO

         3675) between the range of 991.0 kg/m3 to 1010.0 kg/m3;

    a CCAI in the range of 780 to 870;

    a flash point (ISO

         2719) no lower than 60°

    C.;

    a total sediment—

    aged (ISO 10307-2) of less than 0.10 mass %;

    a carbon residue—

    micro method (ISO

         10370) less than 20.00 mass % and wherein the Product Heavy Marine Fuel Oil has a sulfur content (ISO 14596 or ISO

         8754) between the range of 0.50 mass % to 0.05 mass % and wherein said Product Heavy Marine Fuel Oil has;

    a maximum of kinematic viscosity at 50°

    C. (ISO

         3104) between the range from 180 mm2/s to 700 mm2/s;

    a maximum of density at 15°

    C. (ISO

         3675) between the range of 991.0 kg/m3 to 1010.0 kg/m3;

    a CCAI in the range of 780 to 870;

    a flash point (ISO

         2719) no lower than 60°

    C.;

    a total sediment—

    aged (ISO 10307-2) of less than 0.10 mass %;

    a carbon residue—

    micro method (ISO

         10370) less than 20.00 mass %.
