Abstract
A process for reducing the environmental contaminants in a ISO 8217 compliant Feedstock Heavy Marine Fuel Oil (Feedstock), the process involving: mixing a quantity of the Feedstock 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 (Product) components of the Process Mixture from the gaseous components and by-product hydrocarbons of the Process Mixture and, discharging the Product. The Product is compliant with ISO standards for residual marine fuel oils and has a maximum sulfur content between the range of 0.05% wt. to 0.50% wt. The Product can be used as or as a blending stock for compliant, low sulfur or ultralow sulfur heavy marine fuel oil. A device for conducting the process is also disclosed.
