the process to dissolve the coal and to transfer externally produced hydrogen to the coal molecules. Catalytic liquefaction resembles solvent extraction, except that hydrogen is added to the coal with the aid of a catalyst. Figure presents the flow diagram of a typical solvent extraction or catalytic
Coal processing or coal beneficiation uses physical (mechanical) and/or chemical methods to remove rocks, dirt, ash, sulphur and other contaminants and unwanted materials to produce highquality coal for energy in both local and export markets.
Coal is a vital component of the world's energy resources, and one that is expected to fill a significant role in meeting our energy needs well into the foreseeable future. Geological science and associated technology are used to find and evaluate the coal resources that will be used to meet these needs, a process referred to as coal exploration,

Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from runofmine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size.
GASIFICATION OF COAL. It is the process of producing synthesis gas mixture of CH4,CO,H2,CO2 and water vapor from coal, water and air. process of gasification chemical reactions Coal is blown through with O2 steam while being heated under pressure The reaction occurring inside gasifier. Reactions: 1. Coal(3C) + O2 + H2O H2 + 3 CO

Since the reserves of good coking coals are being depleted, coal preparation is necessity for a modern cokeoven plant. In addition, with the development of large capacity units in cokemaking and blast furnace technology, the better quality and uniformity of feed coals has been required.

mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between and mm ( and in.). The desired size depends on the response of the coal to coking reactions and the ultimate coke strength that is required.
specification, most suppliers process the raw coal using dense medium processing. Although dense medium is the most efficient process available, it is expensive and it produces a wet product which requires dewatering by centrifuging and/or drainage on product stockpiles.
