CHARFUEL ® COAL REFINING PRODUCTS. A significant advantage of the Charfuel® process is its flexibility. The technology can produce an array of products for which lucrative markets already exist—and which are in need of additional supply. Like oil, the refined components of coal are far more valuable (many multiples) than the coal itself.

Coking 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 .

The 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.

Coal 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.

The 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.

Refined coal Last updated February 05, 2020. Refined coal 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. [1] Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the ...
