Why coal is solid and petroleum liquid?
Coal is a solid, oil is a liquid and natural gas is a vapor (gas). Basically, coal is purely vegetation in strata. It is always “longer-chain” hydrocarbons. Oil may be formed from animal as well as plant decomposition, and has relatively shorter hydrocarbon chains, making it a liquid instead of a solid.
How is coal turned into liquid?
Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. In the direct route, coal is pulverized and reacted with a catalyst, then hydrogen is added under high pressures and temperatures in the presence of a solvent to produce a raw liquid fuel.
What is the liquid form of coal?
Coal liquefication, also called Coal to Liquid (CTL) technology is an alternative route to produce diesel and gasoline and makes economic sense only in a world of high crude oil prices.
What is the solid form of petroleum?
The term is often restricted to the liquid form, commonly called crude oil, but, as a technical term, petroleum also includes natural gas and the viscous or solid form known as bitumen, which is found in tar sands. …
What is the major difference between coal and petroleum?
Difference between Coal and Petroleum
| Coal | Petroleum |
|---|---|
| Coal is found in solid state | Petroleum is found in liquid state |
| Cost of transportation of coal is high since it is hard and bulky | Cost of transportation of petroleum is low because it is a liquid |
Can you extract oil from coal?
Coal oil is a shale oil obtained from the destructive distillation of cannel coal, mineral wax, or bituminous shale, once used widely for illumination. Refined hydrocarbons of the alkane series with 10 to 16 carbon atoms are the same thing whether taken from coal or petroleum.
What is the origin of coal and petroleum?
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.
What are the similarities of coal and petroleum?
Both of them are fuel. They both are abundant fossil fuels. They both can be used for industrial and domestic purposes. They both liberate harmful gases when burnt during the process of combustion.
