Abstract
A multi-stage process for transforming a high sulfur ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process that produces a Product Heavy Marine Fuel Oil that can be used as a feedstock for subsequent refinery process such as anode grade coking, needle coking and fluid catalytic cracking. The Product Heavy Marine Fuel Oil exhibits multiple properties desirable as a feedstock for those processes including a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process is also disclosed.

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, wherein the Feedstock Heavy Marine Fuel Oil has a maximum kinematic viscosity at 50° C. (ISO 3104) and a density at 15° C. (ISO 3675) resulting in a CCAI is in the range of 780 to 870;
- a flash point (ISO 2719) no lower than 60.0° C.;
- a total sediment-aged (ISO 10307-2) of less than 0.10% wt.;
- a carbon residue-micro method (ISO 10370) less than 20.00% wt., and a maximum aluminum plus silicon (ISO 10478) content of 60 mg/kg:
- 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 the Product Heavy Marine Fuel Oil from the Process Mixture to form a Product Heavy Marine Fuel Oil;
- and, discharging the Product Heavy Marine Fuel Oil to a subsequent refinery unit.
