Production of Coal-Based Fuels and Value-Added Products

changed our emphasis to a coal-based replacement for JP-8. The project has three major activities fuel production, stability, and combustion. At first we needed a ready source of coal-derived liquids to use as a surrogate, to make fuel for the stability and combustion portions of the project while routes to coal liquids were being developed.

ENVIRONMENTAL PROBLEMS WITH COAL, OIL, AND GAS

Coal burning, which now generates most of our electricity, is by far the most polluting process. According to EPA estimates, 5 fossil fuel burning in electric power plants produces 64% of all U.S. releases of sulfur dioxide, 27% of the particulates, and 31% of the nitrogen oxides, but less than 1% of the carbon monoxide or hydrocarbons.

Learn About Metallurgical Coal The Balance

A lack of reliable supply of individual coal grades means that coke-makers today often use blends of up to 20 different coals in order to offer steelmakers a consistent product. Approximately 1.5 metric tons of metallurgical coal are required to produce 1 metric ton (1,000 kilograms) of coke.

Heavy Media Separation Process

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

Coal-conversion process United States Steel Corporation

Jun 13, 1978By combining heavy oil with char and coal, the amount of heavy oil which would otherwise need to be disposed of in other areas of the process is reduced. Coal liquefaction is the rendering of coal into more useful liquids and gases by causing an increase in the hydrogen to carbon ratio of the original coal.
