What are olefin and aromatic in the context of oil refinery?

The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers). Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions. Chemical plants produce olefins by steam cracking … Pogledajte više Petrochemicals (sometimes abbreviated as petchems ) are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as Pogledajte više The following is a partial list of major commercial petrochemicals and their derivatives: • Pogledajte više • Petroleum • Petroleum products • Instrumentation in petrochemical industries • Organization of the Petroleum Exporting Countries Pogledajte više In 1835, Henri Victor Regnault, a French chemist left vinyl chloride in the sun and found white solid at the bottom of the flask which was polyvinyl chloride.
