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.

Research Progress of the Modification in Sulfur Concrete

Sulfur concrete (SC) is a relatively new type of construction material with advantages of the strong corrosion resistance and quick setting and hardening, which has been applied in construction engineering. SC is brittle with large hardening shrinkage, so it needs to be modified in the process of use. How SC can be modified is a key point of its improvement.
