Coal-to-Liquids - an overview | ScienceDirect Topics

Indirect coal-to-liquids processes rely on the conversion of coal to syngas, in the same manner as the IGCC power stations discussed earlier. Instead of cleaning and combusting the syngas, however, indirect CtL processes use the syngas in catalytic conversion processes to produce specific hydrocarbon fuels.

05-01-2012· Unlike coalfired power plants, where coal’s combustion emits pollutants, CTL fuels are as clean or cleaner at their end use as today’s liquid fuels. But the process by which the fuels are made can be very carbon-intensive — in fact, more so than any other fuel — and that has many people concerned.

Turning carbon waste into liquid fuel | Energy Transition

One process could involve capturing a coal power station’s CO 2 waste emissions and using it as the feedstock for the liquid fuel, instead of mining coal to feed into the refinery. This process can also use renewable solar PV electricity to drive a key refining process (involving electrolysing steam and CO 2).

Liquid fuel from coal – Parliament of Australia

Coal-to-liquids technology. Production of liquid fuel from coal, known as coal-to-liquids (CTL) technology, involves either direct or indirect liquefaction. CTL can utilise either black or brown coal. The direct process has not yet been commercially proven, but potentially provides a lower cost path with fewer steps and associated technologies.

What is “liquid coal”? – Jean-Marc Jancovici

01-07-2012· As the process of gasification has been designed by two engineers, Fischer and Tropsch, the “coal to liquids” or “gas to liquids” technologies are sometimes designed under the expression “Fischer-Tropsch process”. The liquid fuels obtained are close to diesel oil, and are therefore perfectly suited to terrestrial or aerial vehicles.

In the coal-to-liquids (CTL) process, the coal is first converted to syngas. It then undergoes the water-gas shift (WGS) reaction, which removes some of the carbon monoxide (CO) from the syngas by converting it to CO 2 , and this is followed by Fischer-Tropsch (FT) to create the liquid fuels.

Two-stage DCL process was developed in recognizing that the conversion process probably proceeds in two steps – first, coal dissolution, in which the coal is converted to a soluble form with high molecular weight but with little change in the average composition from the original coal; and a second stage in which the dissolved products are upgraded to lower-boiling liquids with reduced ...
