Coal liquefaction is a process of changing 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)
The process compromising: mixing solid coal particles having particle size ranging from about 20 mesh to about 400 mesh with hydrocarbon liquid solvent in a solvent/coal weight ratio at least sufficient to provide a flowable coal/oil slurry feed of the solid coal particles, a substantial portion of the hydrocarbon solvent having a normal ...
A chemical process used for turning coal into liquid fuels that has the potential for producing hundreds of thousands of barrels per day of hydrocarbon liquids and other byproducts—including electricity—is described. The key to converting coal to liquids is the FischerTropsch (FT) process, which was invented in Germany in the 1920s.

Provide ONE (1) advantage and ONE (1) disadvantage of this process over indirect process. [8 marks] b. State and describe briefly ONE (1) process to remove H2O from ...
In the 1920s, Franz Fischer and Hans Tropsch of the Kaiser Wilhelm Institute developed a catalyst to convert hydrogen and carbon monoxide obtained from gasification of coal to hydrocarbon liquids. Because the coal is first gasified before conversion to liquid fuels, the FischerTropsch (FT) process for CTL is known as a type of Indirect Coal ...

The conversion of synthesis gas to liquid molar fuels by means of a cobalt FischerTropsch catalyst composition is enhanced by the addition of molybdenum, tungsten or a combination thereof as an additional component of said composition. The presence of the additive component increases the olefinic content of the hydrocarbon products produced.
The process which converts solid coal into liquid hydrocarbon fuel is known as coal liquifaction. The liquefaction converts solid coal directly into liquid form with no intermediate step. Suggest Corrections. 0.

First, we need to know that the process of converting solid coal into liquid hydrocarbon fuel is called coal liquefaction. There are two main methods of coal liquefaction: Step 2/3 1. Direct coal liquefaction: This method involves heating coal in the presence of a catalyst and hydrogen gas under high pressure and temperature.
The process typically uses the technique of heating under pressure (up to 470°C, 200 bar) and hydrogenation where hydrogen is added to a coalwater slurry. The slurry increases the H/C ratio to a crude oil level and removes impurities such as sulfur, nitrogen, and oxygen.
