Heavy marine fuel oil composition

The product of a process comprising:

• a) combining a quantity of a heavy marine fuel oil feedstock with an amount of an Activating Gas to form a Feedstock Mixture, wherein immediately prior to being combined with the Activating Gas, the heavy marine fuel oil feedstock is compliant with ISO 8217:2017 Table 2 as a residual marine fuel, except the heavy marine fuel oil feedstock has an Environmental Contaminants concentration greater than 0.5% wt. and wherein the Environmental Contaminants are selected from the group consisting of:
• sulfur;
• vanadium, nickel, iron, aluminum and silicon and combinations thereof, and wherein the sulfur concentration is at least 0.5% wt;
• b) contacting said Feedstock Mixture in at least one reactor vessel under reactive process conditions of hydrodemetallization and hydrodesulfurization, and hydrocracking less than 10% wt of the total mass balance to form a Process Mixture, wherein the at least one reactor vessel is operationally configured to utilize one or more catalyst materials selected from the group consisting of:
• hydrodesulfurization catalyst materials, hydrotransition catalyst materials, hydrodemetallization catalyst materials, inert catalyst materials, and combinations thereof, and subsequently discharging the Process Mixture from the at least one reactor vessel;
• c) sending the Process Mixture via fluid communication from the at least one reactor vessel to at least one second vessel and separating a liquid hydrocarbon component from the Process Mixture, wherein the liquid hydrocarbon component is compliant with ISO 8217;
• 2017 Table 2 as a residual marine fuel, and has an Environmental Contaminates concentration of less than 0.5 wt %, and wherein the Environmental Contaminants are selected from the group consisting of:
• sulfur;
• vanadium, nickel, iron, aluminum and silicon and combinations thereof;
• d) discharging the liquid hydrocarbon component from said at least one second vessel
• e) blending a predetermined portion of the liquid hydrocarbon component discharged from step d with a minority portion of a Diluent, and wherein the Diluent Materials are independently selected from the group consisting of:
• hydrocarbon materials;
• non-hydrocarbon materials;
• and, solid materials and combinations thereof;
• and forming the claimed product, wherein the claimed product is a heavy marine fuel oil composition that is fungible as a bunker fuel for ocean going ships, and wherein the heavy marine fuel oil composition is compliant with ISO 8217:2017 Table 2 as a residual marine fuel, and has an Environmental Contaminates concentration of less than 0.5 wt %, and wherein the Environmental Contaminants are selected from the group consisting of:
• sulfur;
• vanadium, nickel, iron, aluminum and silicon and combinations thereof.
