The types and range of chemicals produced from petroleum and natural gas are extremely diverse and extensive. The main raw materials for petrochemicals are various petroleum fractions and refinery gases produced from the petroleum refining process, as well as oilfield gas and natural gas. Petroleum fractions (mainly light oils), through hydrocarbon cracking and cracked gas separation, can produce olefins such as ethylene, propylene, and butadiene, and aromatics such as benzene, toluene, and xylene. Aromatics can also be obtained from the catalytic reforming of light petroleum fractions. Light petroleum fractions and natural gas, through steam reforming, and heavy oil, through partial oxidation, can produce synthesis gas, which is then used to produce synthetic ammonia, synthetic methanol, etc. Starting from olefins, various alcohols, ketones, aldehydes, acids, and epoxides can be produced. With the development of science and technology, the aforementioned olefins and aromatics can be processed to produce high-polymer products including synthetic resins, synthetic rubber, and synthetic fibers, as well as a series of products such as surfactants and other fine chemicals. Therefore, the scope of petrochemicals has expanded to most areas of polymer chemistry and fine chemistry. Petrochemical production is generally combined with petroleum refining or natural gas processing, mutually providing raw materials, by-products, or semi-finished products to improve economic efficiency (see integrated petrochemical enterprises).
