view moreHow coal is processed. Before coal is shipped long distances, it undergoes a process of preparation to lower shipping costs and prepare it for use in power plants. Preparation generally includes crushing the coal and removing heavy, extraneous non-coal materials.
view moreCoking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a .

view moreThe production of hydrocarbons from coal - 1984-1-1 The production of hydrocarbons from coal Mark E. Dry There are two main routes for converting coal to refined hydrocarbons. The first is to add hydrogen directly to coal under high pressure and temperature and then refine the resultant crude products.
view moreCoal production is down by about a third overall, but the production of refined coal has actually been growing pretty substantially in the last few years. So, that's in large part because of this federal government subsidy that, Brian, you estimate to be on the order of $1 billion each year in tax credits to support refined coal.
view moreThe advantages of the refined coal process are more efficient transportation and the ability of utilities to switch to a fuel made of 100 percent refined coal or a blend of raw and refined coals in order to achieve lower emissions and greater efficiency. A disadvantage is that the industry requires significant subsidies.
