Kerosene is a thin, clear liquid formed from hydrocarbons which are obtained from the distillation of petroleum. It is miscible in petroleum solvents, but immiscible in water. Odorless Kerosene undergoes a desulfurization and dearomatization process via catalytic hydrodesulfurization and hydrogenation of aromatic hydrocarbons It has numerous uses in both industrial and consumer settings, and is sometimes spelt kerosine in scientific and industrial usage. It derives its name from the Greek word keros, which means wax. Kerosene is used as jet fuel and rocket fuel, and is a common source of fuel for cooking and lighting.
