A process for reducing the environmental contaminants in a ISO 8217 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 8217 for residual marine fuel oils and the sulfur and Specific Contaminants have concentration less than 0.5 wt %., wherein the Specific Contaminates are selected from the group consisting of: vanadium, sodium, aluminum, silicon, calcium, zinc, phosphorus, nickel, iron and combinations thereof. 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 new family of crystalline microporous metallophosphates designated AlPO-90 has been synthesized. These metallophosphates are represented by the empirical formula
R.sup.+.sub.rM.sub.m.sup.2+EP.sub.xSi.sub.yO.sub.z
where R is an organoammonium cation, M is a framework metal alkaline earth or transition metal of valence +2, and E is a trivalent framework element such as aluminum or gallium. The AlPO-90 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.
