1. A process for the production of a Product Heavy Marine Fuel Oil, the process comprising: mixing a quantity of a Heavy Marine Fuel Oil feedstock with a quantity of an Activating Gas to give a Feedstock Mixture, wherein immediately prior to said mixing said Heavy Marine Fuel Oil feedstock is compliant with ISO 8217 (2017) as a Table 2 residual marine fuel, except said Heavy Marine Fuel Oil feedstock has one or more Environmental Contaminants selected from the group consisting of: sulfur; vanadium, nickel, iron, aluminum and silicon and combinations thereof, and wherein said one or more Environmental Contaminants have a combined concentration greater than 0.5% wt.;
distributing said Feedstock Mixture to a Reaction System, wherein the Reaction System is comprised of one or more reactor vessels, and wherein each of the one or more reactor vessels is independently selected from the group of operational configurations consisting of: dense packed fixed bed trickle reactor; dense packed fixed bed up-flow reactor;
ebulliated bed three phase up-flow reactor; fixed bed divided wall reactor; fixed bed three phase bubble reactor; fixed bed liquid full reactor, fixed bed high flux reactor; fixed bed structured catalyst bed reactor; fixed bed reactive distillation reactor and combinations thereof, and wherein said Reaction System is configured such that the Feedstock Mixture is first passed through at least one first catalyst bed under reactive conditions, wherein the at least one first catalyst bed contains one or more catalyst materials with hydrodemetallization activity; and then subsequently passed through at least one second catalyst bed under reactive conditions, wherein the at least one second catalyst bed contains one or more catalyst materials with mixed hydrodemetallization and hydrodesulfurization activity, and then subsequently passed through at least one third catalyst bed under reactive conditions, wherein the at least one third catalyst bed contains one or more catalyst materials with hydrodesulfurization activity, thereby forming a Process Mixture from said Feedstock Mixture, wherein said Process Mixture comprises one or more bulk gaseous components, one or more liquid hydrocarbon components, and one or more residual gaseous components entrained in said hydrocarbon liquid components, wherein said one or more liquid hydrocarbon components comprises a Product Heavy Marine Fuel Oil component; receiving by fluid communication said Process Mixture in at least one separation vessel and separating the one or more bulk gaseous components of said Process Mixture from a combined one or more liquid hydrocarbon components, and one or more residual gaseous components entrained in said hydrocarbon liquid components; receiving by fluid communication the combined one or more liquid hydrocarbon components, and one or more residual gaseous components entrained in said hydrocarbon liquid components in at least one Oil Product Stripper System and separating the Product Heavy Marine Fuel Oil component from the combined one or more liquid hydrocarbon components, and one or more residual gaseous components entrained in said hydrocarbon liquid components; and, discharging said Product Heavy Marine Fuel Oil component from the Oil Product Stripper System forming the Product Heavy Marine Fuel Oil.
