Abstract:
A system for processing liquid fuel mixed by coal and oil, a method of processing mixed liquid fuel is provided to solve a pollution problem by dust generated when carrying coal, to cause no contamination by the dust or spontaneous ignition because char particles are processed to 1 ~ 3 and made into slurry and to be used as clean fuel since the combustion residue nearly does not remain after combustion. The primary crusher(200) firstly pulverizes char particles into 0.5mm or less. A fine pulverizer(300) shatters the char particles at a hypersonic speed by using the gas supplied from outside after the first grinding. A filter passes char particles having size of 1 ~ 3 of the char particles pulverized in a fine pulverizer. A depositing water tub collects char particles filtered through the filter in underwater(400). The char particles are desulfurized by mixing the char particles of 50 parts by weight in the depositing water tub(500), water of 5 ~ 10 parts by weight and oil of 40 ~ 45 parts by weight.
Abstract:
A preparation system of a mixed liquid fuel and a preparation method of a mixed liquid fuel using the same are provided to solve a pollution problem generated due to dust and the like when transporting coal, make it not necessary to be apprehensive of pollution or spontaneous combustion due to dust by processing coal into coal powder with a particle size of 4 to 10 mum and converting the coal powder into a slurry, and use the mixed liquid fuel as a clean fuel by allowing combustion residues to be hardly remained even after combustion. A preparation system of a mixed liquid fuel comprises: a first pulverizer(200) for primarily pulverizing coal grains into coal particles with a particle size of not greater than 0.5 mm; a fine pulverizer(300) for rotating the coal particles to a supersonic speed using gas with a specified pressure supplied from the outside to pulverize the coal particles; a filter for passing coal particles with a particle diameter of 4 to 10 mum only in the coal particles that have been pulverized in the fine pulverizer; a collecting water tank(400) for collecting in the water the coal particles that have passed through the filter; and a centrifuge(500) for mixing 30 to 70 weight parts of the coal particles that have been collected in the collecting water tank and supplied from the collecting water tank, 5 to 10 weight parts of water, and 30 to 70 weight parts of oil, and removing sulfur and ash from the coal particles of the mixture. Further, the oil is one selected from a group consisting of kerosene, diesel oil, BC oil and DMU-101.

Abstract:
A liquid fuel derived from processed biomass having extremely low water content and suitable for use in diesel engines or as an additive to petroleum based fuels, or which can be used as a petroleum or coal slurry substitute in those uses where a lower cost fuel have reduced emission is desired, is described.
Abstract:
The disclosures described herein provide for a gasification feedstock which includes a mixture of a solid feedstock with a liquid feedstock. The solid feedstock includes a heating value of less than approximately 20 Megajoules/kilogram (MJ/kg), expressed on a wet basis. The non-aqueous liquid feedstock includes a heating value of greater than approximately 14 MJ/kg, expressed on a wet basis. The resulting feedstock is useful as a gasification fuel.
Abstract:
The present invention relates to transportable product for the transportation of paraffinic wax and methods of transporting using this transportable product. The transportable product comprises 90 to 20 weight % of a hydrocarbonaceous liquid, wherein the hydrocarbonaceous liquid comprises =75 weight % of a liquid selected from the group consisting of naphtha, heavy oil, distillate, lubricant base oil, and mixtures thereof, and 10 to 80 weight % of wax particles, wherein the wax particles comprise = weight % of wax particles larger than 2.4 mm. The transportable product and methods of transporting according to the present invention are able to accommodate a relatively high weight % of paraffinic wax particles in the transportable product while avoiding interparticle adhesion and clumping by ensuring that the wax particles are not too small and the amount of small wax particles is not excessive.

Abstract:
A grinding mixture with a pH of from 5-12 which contains about 60-82 volume percent of one or more carbonaceous materials, about 18-40 volume percent of one or more carrier liquids, and from about 0.01-4.0 weight percent of one or more dispersing agents. The mixture is comprised of at least two consists of carbonaceous material, one of which contains particles smaller than 53 microns. There is also disclosed a process for preparing a carbonaceous slurry comprising the steps of grinding the aforementioned grinding mixture until it contains a consist whose particles are in substantial accordance with a specified particle size distribution. The slurry produced by this process, and the compact in the slurry, also are described.
