US4270926A Process for removal of sulfur and ash from

A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.

US4272250A Process for removal of sulfur and ash from

A process for reducing the sulfur and ash content of coal particles wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates having modified particle size and density characteristics. The coal-oil aggregates are separated from ash and mineral matter in the slurry by gravitational means.

Process for removal of sulfur and ash from coal Atlantic

For example, U.S. Pat. Nos. 3,856,668 and 3,665,066 disclose processes for recovering coal fines by agglomerating the fine coal particles with oil. U.S. Pat. Nos. 3,268,071 and 4,033,729 disclose processes involving agglomerating coal particles with oil in order to provide a separation of coal from ash. While these processes can provide some benefication of coal, better removal of ash and iron

How to Remove Sulphur from Coal

Reducing the inorganic sulfur in coal to tolerable limits by physical beneficiation, including flotation, as now practiced, still is relatively inefficient and has not kept pace with the more sophisticated physical beneficiation approaches employed by the nonfuel minerals industry in general. As one phase of a broad program conducted by the Mineral Resources Institute on the sampling and

New process removes sulfur from coal before burning

A desulfurization process removes sulfur from coal before it is burned, eliminating or minimizing sulfur dioxide emissions, an acid rain precursor. Historically, research has focused on post-combustion flue-gas desulfurization (FGD) techniques to reduce sulfur dioxide emissions. Besides offering a new approach to emissions reduction, say industry experts, the technology has revolutionized coal
