    Abstract: A substantially water-free, high solid content, stable and combustible fuel slurry and the method for producing the same are disclosed. The slurry includes about 5 to about 50 weight percent of solid particulate carbonaceous material, such as powdered coal, with substantially the entire balance of the slurry being comprised of liquid hydrocarbon fuel, such as Bunker C (No. 6) fuel oil, a slurry suspension stabilizing agent and a slurry viscosity reducing agent. The slurry viscosity reducing agent is preferably a detergent, which is added in an amount to reduce the viscosity of the slurry to a pumpable and flowable level without the addition of substantial quantities of water. In the process, the addition of detergent as the slurry viscosity reducing agent prevents formation of a gel during storage of the slurry.

    Abstract: This document relates to a fuel oil composition comprising: (i) a solid hydrocarbonaceous and/or solid carbonaceous material, wherein the material is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 20 microns in diameter; and (ii) a liquid fuel oil; wherein the solid hydrocarbonaceous and/or solid carbonaceous material is present in an amount of at most about 30 by mass (% m) based on the total mass of the fuel oil composition. The invention further relates a process for the preparation of this fuel oil composition, a method of changing a grade of a liquid fuel oil, and a method for adjusting the flash point of a liquid fuel oil.
