Petroleum became the primary source of hydrocarbons for chemical feedstocks, beginning in about 1850 with the discovery of easily extracted cmde oil in eastern Pennsylvania and in the Ural mountains of Russia. The gases from the primary distillation of cmde oil and the light products from FCC, catalyticfreforming, and hydroprocessing are ideal mixtures of C2 to Cg alkanes that can be used to make many chemicals. Petroleum products are also cleaner than those from coal, producing no ash and less sulfur.
