ABSTRACT:
A process to produce a flowable fuel or fuel supplement from solid and/or liquid waste, such as industrial waste. A system to carry out the process includes producing from the solid and/or liquid industrial waste a solid char and vaporize liquids, recombining the char and the liquids, recovered from the wastes feed, to form a feed slurry containing solids, combining the feed slurry with additional combustible waste liquids which are added at a rate and amount to obtain a fuel slurry of specified properties, particularly specified viscosity and BTU content, subjecting the feed slurry and additional wastes to conditions of attrition in at least one attrition zone to produce a product slurry containing solids of fuel size, recovering the fuel slurry which be used as fuel in partial oxidation processes. The liquid waste may be collected as a product, particularly if they are high in organic compounds.
