Brief history of coaltoliquids Coaltoliquids operations are not new technology. The original FischerTropsch process was developed by German researchers. Gasified coal or natural gas was used to produce paraffin wax that was then refined into diesel, naphtha, and liquid petroleum gases, including propane and butane.

CoaltoLiquids (CTL) is a process of converting coal to fuels such as diesel or gas. For diesel, the process involves first building a plant to convert coal to gas and then another plant to covert the gas to a liquid. The resultant liquid fuel is known as synthetic fuel or synfuel.

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. This process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).

Coal to liquids via the FTS process is an alternative technology for oil production, utilizing vast Thar coal resources in Pakistan. The technology can also play a key role in countering booming imports of these hydrocarbon liquids in the country. However, energy usage and GHG emissions of FTS plants are relatively very high due to their long ...

DCL is termed direct because the coal is transformed into liquid without first being gasified to form syngas (which can then in turn be transformed into liquid products). The latter twostep approach, the coal to syngas to liquids route is termed indirect coal liquefaction (ICL). Therefore, the DCL process is, in principle, the simpler and ...

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.

The process, which they named for themselves, involves converting gas into liquid fuels. While there are alternatives to the FischerTropsch process, it is the most extensively tested and widely used method for creating synfuels today. Historically, synfuels were first used extensively to fuel military vehicles in World War II Germany.

4 Liquefaction. Coal liquefaction is the process of making a liquid fuel from coal. The fundamental difference between coal, a solid, and liquid fuels is that the liquid fuels have a higher hydrogen:carbon ratio. Liquid fuels have lower ash contents and are easier to upgrade (, to remove unwanted impurities such as nitrogen and sulfur). ...
