Abstract:
A process for reducing the environmental contaminants in a ISO8217 compliant Feedstock Heavy Marine Fuel Oil, the process involving: mixing a quantity of the 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 to form a Process Mixture from the feedstock mixture; separating the Product Heavy Marine Fuel Oil liquid components of the Process Mixture from the gaseous components and by-product hydrocarbon components of the Process Mixture and, discharging the Product Heavy Marine Fuel Oil. The Product Heavy Marine Fuel Oil is compliant with ISO 8217A for residual marine fuel oils and has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05% wt. to 1.0 mass. The Product Heavy Marine Fuel Oil can be used as or as a blending stock for an ISO 8217 compliant, IMO MARPOL Annex VI (revised) compliant low sulfur or ultralow sulfur heavy marine fuel oil. A device for conducting the process is also disclosed.

Claim (Index 1):
A heavy marine fuel oil product that is ISO 8217: 2017 compliant, is of merchantable quality, and has a sulfur content (ISO 14596 or ISO 8754) less than 0.5 wt %, said product being produced by a process comprising:\n a) combining a predetermined quantity of a Feedstock Heavy Marine Fuel Oil that is compliant with ISO 8217: 2017 and has a sulfur content (ISO 14596 or ISO 8754) greater than 0.5% wt. with a predetermined amount of an Activating Gas to form a Feedstock Mixture; b) bringing the Feedstock Mixture up to predetermined process conditions of temperature and pressure to form a heated and pressurized Feedstock Mixture; c) contacting said heated and pressurized Feedstock Mixture in at least one reactor vessel with one or more catalyst systems selected from the group consisting of: an ebulliated bed supported transition metal heterogeneous catalyst, a fixed bed supported transition metal heterogeneous catalyst, and a combination of ebulliated bed supported transition metal heterogeneous catalysts and fixed bed supported transition metal heterogeneous catalysts, wherein said contacting takes place under reactive process conditions to form a Process Mixture; d) removing the Process Mixture from being in contact with the one or more catalyst systems in the at least one reactor vessel and sending the Process Mixture via fluid communication from the at least one reactor vessel to at least one second vessel for separating the Liquid Components of the Process Mixture from the Gaseous Components of the Process Mixture; e) sending by fluid communication the Liquid Components of the Process Mixture from the at least one second vessel to at least one third vessel, and removing from the Liquid Components of the Process Mixture any residual gaseous components and any by-product hydrocarbon components to form said heavy marine fuel oil product; and, f) discharging from said at least one third vessel said heavy marine fuel oil product.
