The proposed RTC has been applied to classify six petroleum products: diesel, gasoline, kerosene, light gas oil, light straight-run, and naphtha.
Cracking of petroleum yields light oils (corresponding to gasoline), middle-range oils used in diesel fuel, residual heavy oils, a solid carbonaceous product known as coke, and such gases as methane, ethane, ethylene, propane, propylene, and butylene.

After complete industrialization of light petroleum oil, hydrocracking processes are gradually applied for heavy oil and VR upgradation.
Upgrading technology can be used to produce light petroleum from heavy crude oil.
Some zeolites are excellent hydrocracking and hydroisomerization acidic catalysts for the conversion of heavy oil to light hydrocarbons in petroleum industry.
First, chromatograms were developed using light petroleum:diethyl ether:acetic acid (70 30 2; per vol)., and then light petroleum:diethyl ether (49 1; v/v) as solvents.
The dry light petroleum extract was subjected to flash chromatography on silica gel, mobile phase light petroleum - EtOAc (ethyl acetate) (100% light petroleum to 100% EtOAc) and 10 fractions (A - J) were obtained.
Fractions D and E (1.131 g, eluted with light petroleum - EtOAc 70 30 - and 60 40 were re-chromatographed on a silica gel column eluted with light petroleum - EtOAc (90 10 to 100% EtOAc) and 27 fractions were obtained.
