The Automobile . When the history of the automobile was heading in the direction of becoming the number one method of transportation. There was created a need for new fuels. In the nineteenth century, coal, gas, camphene, and kerosene made from petroleum were being used as fuels and in, automobile engines required fuels that needed petroleum as a raw material.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

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.

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 syngas to eliminate impurities, including sulfur and nitrogen, and converting it into either gasoline or diesel. This fuel is said to be cleaner than gasoline because it is sulfurfree.
