Fluid coking is a process which converts heavy residual crude into lighter products such as naphtha, kerosene, heating oil, and hydrocarbon gases. The "fluid" term refers to the fact that solid coke particles behave as a fluid solid in the continuous fluid coking process versus the older batch delayedcoking process where a solid mass of coke ...

Coal liquefaction Energy Education

The indirect route is composed of 2 steps: First, coal is gasified with steam and oxygen to produce a synthesis gas (syngas), which is then cleaned to rid of dust, tar, and acid gases. The second step reacts the synthesis gas with a catalyst in the FischerTropsch process, which converts the syngas into a range of hydrocarbon fuels such as ...

direct and indirect. As the names imply, direct processes directly convert coalbased hydrocarbons into liquid fuels, while indirect processes use an intermediate process (gasification) to convert the coal into a gaseous fuel (syngas) before further refining the syngas into liquid fuels. Exhibit 21 gives a general overview of the processes ...

Is coal to liquid more efficient than gasoline? HowStuffWorks

Indirect liquefaction the type of technology used in the involves two steps: first turning coal into a gas, a balanced mix of hydrogen and carbon monoxide called syngas. Then, the gas is turned into a liquid that is used as fuel. This is done most often through the FischerTropsch process, which involves chemically refining the ...

The precise chemical structures vary depending on the type of fossil fuel (coal, oil, or natural gas). The molecules in coal tend to be larger than those in oil and natural gas. Coal is thus solid at room temperature, oil is liquid, and natural gas is in a gaseous phase. Specifically, coal is a black or dark brown solid fossil fuel found
