Synthetic, or carbonneutral, fuels capture CO₂ in the manufacturing process. In this way, this greenhouse gas becomes a raw material, from which gasoline, diesel, and substitute natural gas can be produced with the help of electricity from renewable sources. One further crucial advantage of the combustion engine using synthetic fuels is that ...
The hybrid process couples features of both CTL and GTL, to decrease the amount of CO 2 emitted per kilogram of liquid fuel produced. In fact, part of the carbon dioxide produced by coal gasification and water gasshift reaction can be converted into syngas by dry reforming using methane.
SYNTHETIC FUELSSynthetic fuels are usually thought of as liquid fuel substitutes for gasoline and diesel fuel made from petroleum sources. In broad context, the source of these synthetics can be any feedstock containing the combustible elements carbon or hydrogen. These include coal, oil shale, peat, biomass, tar sands, and natural gas.

It produces condensable coal tar, oil and water vapor, noncondensable synthetic gas, and a solid residue char. One typical example of carbonization is the Karrick process. In this lowtemperature carbonization process, coal is heated at 680 °F (360 °C) to 1,380 °F (750 °C) in the absence of air. These temperatures optimize the production ...
24 August, 2005. Sasol has produced almost 1,5 billion barrels of synthetic fuel from about 800 million tonnes of coal since the first sample of synthetic oil from coal was produced fifty years ago at its Sasolburg plant near Johannesburg in South Africa on 23 August 1955. Regarded as a world technology leader in the production of coalto ...
Both the FischerTropsch and MTG processes convert coal into synthesis gas before converting it to the final liquid products. However, their respective product slates are very different.
