ABSTRACT OF THE DISCLOSURE A method of solvent refining coal to produce normally solid solvent refined coal which can be used for the manufacture of high quality electrode coke, includes a...
Refined coal is the product of the coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals, raising their calorific values. [1]
Hydro-refining of CPCO can effectively use the copious hydrogen in the fraction from petroleum and make the aromatics from coal to be hydrogenated and saturated, thus giving much more amount of saturated cyclanes in HCPCO by the probably synergistic effect. Table 1. Major SCs and cyclane species in CPCO and HCPCO.
The solvent-refined coal process (SRC) is largely free of ash and so low in sulfur content that it can be burned without flue-gas desulfurization. The SRC, while still in the liquid form, is now being investigated as an intermediate product to be further upgraded into liquid boiler and turbine fuels. The segment of the process that is the ...
Coal-petroleum co-processing refers to the thermal and catalytic hydro-treatment of slurry mixing lignite or subbituminous coals with inferior petroleum residues on the conventional petroleum refining plant. In this process, hydro-liquefaction of coal and hydrocracking of petroleum residues occur simultaneously [18].
Such solvent-refined resin, at the present time, has a market value of about 0.50% per lb as a chemical commodity and can be used in the ink, adhesive, rubber, varnish, paints, coatings, and thermoplastics industries. A detailed study of batch solvent refining of resin concentrates from the Wasatch Plateau coal is in progress at the University ...
Almost all the refining capacity on the continent is near the Mediterranean coastline, while SA, by far the biggest refiner in Sub-Saharan Africa, has closed all but one of its refineries,...
A UK bituminous coal was co-processed with five different petroleum residues, and with hydrotreated feedstocks, in a simulation of the British Coal Corporation's two-stage liquid solvent extraction process. One-stage co-processing in the presence of a catalyst and hydrogen gas was also investigated.
The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels and tall, skinny towers. Reforming uses heat, moderate pressure, and catalysts to turn naphtha, a light, relatively low-value fraction, into high-octane gasoline components. Treatment The finishing touches occur during the final treatment.
METHOD FOR REFINING COAL European Patent EP2304004 Kind Code: B1 Abstract: A method of processing coal to remove sulfur and other contaminants by mixing coal in a solution of aqueous ammonia having a selected concentration range (preferred range of 3%-5%) of ammonia to water in a reaction vessel.
The refined coal product may be separated from the phenol solvent by conventional filtration. The refined product may then be additionally stripped of residual phenol by any suitable method, for example, by steam stripping and/or by washing with aqueous NaOH solution, such as a 10% NaOH wash. The phenol-water mixture may then be distilled and ...
The first section discusses the refining of coal syncrude/petroleum crude blends in existing petroleum refin- eries versus the refining of coal syncrudes in grass-root coal- liquid refineries. The next section is an analysis of grass-root coal-liquid refineries for H-Coal, SRC-II, and EDS syncrudes. It includes an overview of refining costs ...

Refined coal is raw coal that has been treated to make it less polluting when burned in a power plant or factory to make steam. It is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values.
It is now used for extracting coal mainly in the Appalachian Mountains of the U.S., in states including Virginia, West Virginia, Tennessee, and Kentucky. MTR is probaby the most controversial coal mining technique. The environmental consequences are radical and severe. Waterways are cut off or contaminated by valley fill. Habitats are destroyed.
However, coal is a polluting fuel, therefore, there is a grave need of deep refining of coal to obtain ashless coal for increasing its efficiency of utilization in order to minimize its impact on environment. The presence of ash in coal also greatly reduces the coal utility because of its deleterious effect on the boiler parts and gasification ...

coal refining process involves thermal hydrocracking which results in "hydrodisproportionation" (rearrangement of hydrogen within the coal molecule) to produce a slate of co-products, just as is done with crude oil in petroleum refining. See Figure I. In the Charfuel® process, pulverized coal is rapidly heated in a reducing at-

The CharFuel ® Coal Refining Process refines raw coal in conceptually the same manner as crude oil is refined to cleanly and economically produce high-value liquid fuels, petrochemicals, and clean power plant feedstock. The CharFuel ® Coal Refining Process is not a supplemental source of alternative energy, but is a predominant source.
How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.
A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel ...
It's actually for the refining process itself of coal that's used in the electric power sector. And so, the refining process is, you take a regular feedstock coals, regular coal, and before it goes into the power plant to be burned, the refiners apply a chemical spray. These can be a number of different chemicals. A common one is calcium bromide.
in the so-called solvent refining of coal, which process can be applied to moderately high rank through to low rank coals, the coal, in a particulate condition is subjected to liquefaction in a...
These fossil fuels are then refined into usable substances such as petrol, kerosene, etc. It is formed by the combination of hydrocarbons and other substances, mainly sulphur. When first collected in its natural form, it is termed as crude oil. This substance is generally characterized by a brownish-black colour.
the invention belongs to the technical field of coal refining, and particularly relates to a coal refining process, which comprises the following steps: primarily treating the mined raw...
Sub-bituminous coal can be formed at a very low temperature of 35℃ to 80℃ while anthracite is formed under a very high temperature of at least 180℃ to 245℃. Also, favourable geology does not only contribute to the formation of coal but other factors like the presence of oxygen also contribute to the high coal deposition.
