2010-1-19 The coal industry has found several ways to reduce sulfur, nitrogen oxides, and other impurities from coal. They have found more effective ways of cleaning coal before it leaves the mine, and coal companies look for low-sulfur coal to mine. Power plants use "scrubbers" to clean sulfur from the smoke before it leaves their smokestacks. In addition,

2021-4-6 The impression seems to prevail that splint-coal invariably is detrimental to the coke-making properties of coal. This impression may be borne out by coals of higher rank than high-volatile A, but table 3 shows the reverse to be true of two high-volatile A coals on which BM-AGA tests were made by the Bureau of Mines.

Thus different types of coal are proportionally blended to reach acceptable levels of volatility before the coking process begins. Natural coke is formed when a coal seam is intersected by a volcanic intrusion. These intrusions heat the surrounding coal in an anoxic atmosphere producing coke in a zone (usually several meters) around the intrusion.

Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
