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.

Desulfurization of Coal EOLSS

3. Coal Cleaning for Sulfur Removal The coal cleaning process has traditionally focused on reducing ash-reforming minerals and not necessarily aimed at removing sulfur in coal until recently. However, increasingly stringent regulations for SOx emissions during coal combustion have encouraged technical development of coal cleaning for sulfur

10 Some Methods of Reducing Sulfur Oxides from Power

Advanced coal cleaning methods may be able to increase the amount of sulfur and ash removed but all of the processes are in their early stages of development and many may be high cost for the extra sulfur removal that is accomplished. A low sulfur—low ash product can be produced from coal and commercial plants may be in operation by 1982–1983.

Desulfurization of high sulfur fine coal using a novel

Oct 15, 2019 The throughput of high-ash and high-sulfur fine-grain coal (0–6 mm) increases year by year.The serious problem of direct combustion is the formation of acid rain and smog.Therefore, the pre-combustion desulfurization and ash reduction can reduce environmental pollution. A combined process of dry separation and microwave desulfurization for the cleaning of the 0–6 mm fine coal was applied.
