Petroleum refining or Oil refining is an industrial process in which crude oil is extracted from the ground and transformed and refined into useful products like Liquefied Petroleum Gas (LPG), kerosene, asphalt base, jet fuel, gasoline, heating oil, fuel oils etc. Crude Oil consists of hydrocarbon molecules. There are three steps in the Petroleum refining process Separation, Conversion ...

Present synthetic liquid fuel processes () Today, synthetic fuel production is synonymous with producing liquid fuel from a mixture of CO and H2 (syngas). Syngas is typically derived from nonrenewable fossilbased resources such as coal and natural gas. Research efforts to use biomassbased materials for syngas production have ...

The conversion of living organisms into fossil fuels is a complex process. As organisms die, most organic matter is oxidized back to CO 2 relatively quickly ... and natural gas is in a gaseous phase. Specifically, coal is a black or dark brown solid fossil fuel found as coal seams in rock layers formed from ancient swamp vegetation.

Methanol is predominantly produced by a coaltomethanol process in China. However, this process is criticized by high CO 2 emissions because of the high carbon contents of coal. The high CO 2 emission and low resource utilization efficiency greatly weaken the competitiveness of the coalto methanol industry.

Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are otherwise difficult to access and transport. The resulting liquid fuel, called synthetic crude oil, can be refined into a variety of fuels, including diesel, gasoline, and aviation fuel.
