A process to produce a flowable fuel or fuel supplement from solid and/or liquid waste, such as municipal waste, industrial wastes or mixtures thereof and the system to carry out the process in which a feed of solid and liquid municipal waste, industrial wastes or mixtures thereof to a treatment zone under conditions of temperature to produce 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.
A process comprising providing a feed of solid and liquid waste to a treatment zone under conditions of temperature to produce a solid char and vaporize liquids, condensing and recovering said vaporized liquids, combining said char and said recovered liquids to form a feed slurry containing solids, combining said feed slurry with additional wastes comprising combustible liquids and recovering said fuel slurry as fuel product.
A process comprising providing a feed of solid and liquid waste to a treatment zone under conditions of temperature to produce a solid char and vaporize liquids, condensing and recovering said vaporized liquids, combining said char and said recovered liquids to form a first slurry containing solids of a first size, combining said first slurry with additional wastes comprising combustible liquids, subjecting said first slurry and additional wastes to conditions of attrition in a first attrition zone to produce a second slurry containing solids of a second size, said second size being smaller than said first size and recovering said second slurry.
A process comprising providing a feed of solid and liquid municipal waste, industrial wastes or mixtures thereof to a treatment zone under conditions of temperature to produce a solid char and vaporize liquids, condensing and recovering said vaporized liquids and recovering said liquids as product.
A process comprising providing a feed of solid and liquid municipal waste, industrial wastes or mixtures thereof to a treatment zone under conditions of temperature to produce a solid char and vaporize liquids, condensing and recovering said vaporized liquids, combining said char and a portion of said recovered liquids to form a feed slurry containing solids, combining said feed slurry with additional wastes comprising combustible liquids, subjecting said 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 said fuel slurry as fuel product.
A process for the production of a fuel from a waste comprising:
