Abstract: A process for the production of a non-agglomerating vanadium coated particle is disclosed comprising the combustion of a carbonaceous material or fuel containing relatively large amounts of vanadium in the presence of an oxidizing gas and a particulate substrate such as sand. The combustion of carbonaceous materials such as petroleum coke or bunker oil high in vanadium and sulfur produce vanadium products that melt at the combustion temperature and coat the firebox and/or heat exchange tubes in which the combustion process is conducted with corrosive vanadium slags. This coating problem is also avoided by the process disclosed.
