Ways with coal

Description

Major research has been devoted to making the processes of coal combustion more efficient and reducing the pollution they cause. Coke, the first smokeless fuel made from coal, has important industrial uses which depend on the grade and strength of the coke. Coke can be carbonized to remove volatile matter which is in turn processed to provide a wide range of industrial materials: pitch, creosote, road tar, and concentrated ammonia solution are some examples. Coal can be gasified and converted into a type of crude oil, which can be fractionally distilled into diesel fuel, gasoline, and chemical raw materials.
