An oil conversion device is a device that heats raw materials derived from crude oil under high temperature and low oxygen conditions, transforming them from [solid] to [liquid] to [gas], and finally cooling the gas to produce oil.

This process, called pyrolysis, involves breaking the chain-like bonds between carbon (C) and hydrogen (H), ultimately resulting in chains of about 6 to 15 units (gasoline to fuel oil).

If the chains are broken down further, they will not revert to liquid at normal temperatures (methane, ethane, propane) and will be produced as by-products along with carbon compounds in the oil conversion device.
