Claim 6:
7. A process for the removal of one or more Environmental Contaminants from a Heavy Marine Fuel Oil feedstock, the process comprising: mixing a quantity of said Heavy Marine Fuel Oil feedstock with a quantity of Activating Gas to give a Feedstock Mixture, wherein prior to mixing with Activating Gas, said Heavy Marine Fuel Oil feedstock complies 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., and wherein said Activating Gas has an ideal gas partial pressure of hydrogen (pw2) greater than 80% of the total pressure of the Activating Gas (P); heating the Feedstock Mixture in a fired heater to give a heated Feedstock Mixture; receiving the heated Feedstock Mixture by fluid communication and distributing by fluid communication the Feedstock Mixture in a Reaction System, wherein the Reaction System is comprised of one or more reactor vessels, 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 distributed to and contacted with at least one first catalyst bed under reactive conditions wherein the first catalyst bed is comprised of catalyst materials independently selected from the group consisting of: a hydrodemetallization catalyst material; a hydrotransition catalyst material; an inert catalyst material; and, combinations thereof; and subsequently distributed to and contacted with at least one second catalyst bed under reactive conditions, wherein the second catalyst bed is comprised of catalyst materials independently selected from the group consisting of: a hydrotransition catalyst material, a hydrodesulfurization catalyst material; an inert catalyst material; and, combinations thereof, and subsequently distributed to and contacted with at least one third catalyst bed under reactive conditions, said third catalyst bed is comprised of catalyst materials independently selected from the group consisting of: a hydrotransition catalyst material, a hydrodesulfurization catalyst material, an inert catalyst material, and combinations thereof, and subsequently distributed to and contacted with at least one fourth catalyst bed under reactive conditions, said fourth catalyst is selected from the group consisting of a hydrotransition catalyst material, a hydrodesulfurization catalyst material, an inert catalyst material, and combinations thereof; and wherein said combined steps of distribution and contacting of the Feedstock Mixture forms 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; 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 the one or more liquid hydrocarbon components, and the one or more residual gaseous components entrained in said hydrocarbon liquid components; receiving by fluid communication the one or more liquid hydrocarbon components, and the one or more residual gaseous components entrained in said hydrocarbon liquid components in at least one Oil Product Stripper System and separating the one of more residual gaseous components from the hydrocarbon liquid components and separating the Product Heavy Marine Fuel Oil component from the 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.
