A process of manufacturing a co-fuel additive for promoting the suspension of coal macroparticles in petroleum fuel liquid incorporates a quantity of pulverulent alkaline fluxing mineral material for modifying the solid and gaseous products that results from combustion of the mixture. Miscible petroleum liquid, a coal anti-sedimentation surfactant and sufficient water to form a water-in-oil emulsion are also included in the additive.

The process of manufacturing a co-fuel composition wherein the suspension of coal macroparticles in a petroleum fuel liquid is promoted during transportation and storage and wherein the solid and gaseous products resulting from the combustion of the co-fuel are modified, said process comprising the steps of: providing a composition of petroleum fuel oil and powdered coal; mixing a coal anti-sedimentation surfactant with a petroleum liquid that is miscible with said petroleum fuel oil and thereafter incorporating in said surfactant mixture a quantity of pulverulent alkaline fluxing mineral material and a quantity of water which is sufficient to form a water-in-oil emulsion with said petroleum liquid and which is sufficient to take up said fluxing mineral material into the enclosed, water phase of said emulsion; and adding said surfactant/mineral mixture to said composition of oil and coal.
