Conversion: Gas oil into petrol. Catalytic cracking is aided by adding hydrogen gas during the hydrocracking process. The CC bonds are broken down using it. The major products from this process are diesels, jet fuel, and LPG. It is based on the fusion of two distinct processes known as catalytic cracking and hydrogenation.

Thermochemical conversion is a method of using heat to convert biomass into usable energy or fuel. Thermochemical conversion routes can be classified into combustion, gasification, liquefaction, pyrolysis, and torrefaction. Aside from combustion, all the other techniques can produce solid, liquid, and/or gaseous biofuels.

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).
