As we know, Crude oil is one of the most important energy in the world it was made natural&shyly from decaying plants and animals living in ancient seas millions of years ago. The scientist usually explores crude oil in the sea bed. The crude oil mainly consists of hydrocarbons. Hydrocarbons are molecules that contain hydrogen and carbon.The pyrolysis oil has a fuel value that is generally 50-70% that of petroleuc based fuels can bu used as boiler fuel or upt\graded to renewable transportation fuels.

the components of pyrolysis oil

Different hydrocarbon chain lengths all have progressively higher boiling points, so they can all be separated by distillation. Crude oil is heated and the different chains are pulled out by their vaporization temperatures. Each different chain length has a different property that makes it useful in a different way.
