Coal Wikipedia

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels and tall, skinny towers. Reforming uses heat, moderate pressure, and catalysts to turn naphtha, a light, relatively lowvalue fraction, into highoctane gasoline components. Treatment. The finishing touches occur during the final treatment.

24 August, 2005. Sasol has produced almost 1,5 billion barrels of synthetic fuel from about 800 million tonnes of coal since the first sample of synthetic oil from coal was produced fifty years ago at its Sasolburg plant near Johannesburg in South Africa on 23 August 1955. Regarded as a world technology leader in the production of coalto ...
