Petrochemical products to synthetic plastics production process and development prospects (uses) in detail! (200 - 300 words) urgent
The light fraction of petroleum and natural gas can be synthesized by steam reforming and partial oxidation of heavy oil. It can produce all kinds of alcohols, ketones, aldehydes, acids and epoxy compounds. With the development of science and technology, the olefins and aromatics by processing can produce polymer products including synthetic resin, synthetic rubber, synthetic fiber and a series of products such as fine chemicals, surface active agent, so the petrochemical category has been expanded to most of the field of polymer chemical and fine chemical industry.
The energy provided by the petrochemical industry is mainly used as fuel for automobiles, tractors, aircraft, ships, boilers, and a small amount of fuel for civilian use. Energy is one of the factors restricting the development of our national economy, the petrochemical industry consumes about 8.5% of the total energy, and the energy consumption should be reduced. 2 petrochemical industry is one of the pillars of the metal industry, metal, inorganic non-metallic materials and polymer synthesis materials, known as the three major materials. The world's petrochemical synthesis of polymer materials currently produce about 1.45 tons, in 1996, China has more than 8 million tons. In addition to synthetic materials, petroleum chemical industry also provides most of the organic chemical raw materials, in belongs to the field of chemical engineering area, in addition to provide chemical and Mineral chemical products, petroleum and chemical raw material for production of various departments in the display skills to the full. 3 petrochemical industry promotes the development of agriculture and agriculture is the basic industry of our national economy. The petrochemical industry accounted for 80% of the total amount of nitrogen fertilizer, promote the use of agricultural plastic film, and the rational use of pesticides and a large number of agricultural machinery required for various types of fuel, the formation of the main force in the petrochemical industry to support agriculture.
The production of petroleum and chemical industry, generally combined with petroleum refining or natural gas processing, to provide raw materials, by-products, or semi-finished products to enhance economic efficiency (see the petrochemical joint venture). Edit this paragraph Petrochemical effect of 1 petroleum and chemical is a leading supplier of petrochemical energy, mainly refers to the oil refinery production of gasoline, kerosene, diesel oil, heavy oil and natural gas is the main oil supply current of primary energy. China produced 80 million tons of fuel oil in 1995. At present, the world's oil and gas consumption accounts for about 60% of total energy consumption, China's coal consumption, oil consumption of less than 20%. The energy provided by the petrochemical industry is mainly used as fuel for automobiles, tractors, aircraft, ships, boilers, and a small amount of fuel for civilian use
The category of petroleum and chemical products produced by petroleum and natural gas is very large and wide in scope. Petroleum chemical raw materials mainly for various petroleum fractions and refinery gas generated from oil refining process, oil and gas, natural gas, etc.. Petroleum fractions (mainly light oil) by pyrolysis of hydrocarbons, separation of pyrolysis gas can produce ethylene, propylene, butadiene, olefin and benzene, toluene and xylene, aromatic hydrocarbons, aromatic hydrocarbon catalytic reforming of petroleum fractions can be derived from the light.
