High Quality Content by WIKIPEDIA articles! Petrochemicals are chemical products made from raw materials of petroleum or other hydrocarbon origin.Although some of the chemical compounds that originate from petroleum may also be derived from other sources (such as coal or natural gas), petroleum is a major source of many. This article is mainly intended to discuss organic compounds or materials that are not burned as fuel (see also Petroleum product). The two main classes of petrochemical raw materials are olefins (including ethylene and propylene) and aromatics (including benzene and xylene isomers), both of which are produced in very large quantities. At oil refineries, olefins are produced mainly from hydrocarbons by processes such as fluid catalytic cracking and steam cracking.
