How crude oil refined oil, in addition to gasoline can be extracted out of something else
Two lubricating oil and greaseLubricating oils and greases are used to reduce friction between parts and to protect parts to extend their service life and save power. They only account for about 5% of the total petroleum products, but they have a wide varietyThree wax, bitumen and petroleum cokeThey are further processed from the production of fuels and lubricants, which produce about a few percent of the crude oil produced
After refining the oil, the products can be broadly divided into four categories:One oil fuelPetroleum fuel is the largest amount of oil, which can be divided into five kinds according to its use and scope of use:1, ignition engine fuel aviation gasoline, gasoline and other vehicles2, jet engine fuel (jet fuel) has aviation kerosene3, compression ignition engine fuel (diesel fuel) has high speed, medium speed, low speed diesel4, liquefied petroleum gas fuel is liquid hydrocarbon5, boiler fuel with furnace fuel oil and marine fuel oil
According to the difference of boiling point of the group, from crude oil refining straight run gasoline, kerosene, diesel oil and lubricating oil distillate severity grading, a process that is crude oil. Then these semi-finished products in some or most of the two crude oil as raw material, processing, refining process, such as catalytic cracking catalytic reforming, hydrocracking and other backward, can improve oil product quality and the yield of light oil.
Four solvents and PetrochemicalsThe latter is an important raw material and intermediate in organic synthesis industryThe exploitation of crude oil, reduce the pressure, natural gas will be separated from the inside. The remaining part of dehydration, salt, gas transfer to the refinery. Through atmospheric and vacuum heating, things will be separated. In different temperature liquefaction things will once be gasoline, kerosene and diesel oil, lubricating oil, asphalt. Each kind of oil after heating and catalyst, methane, ethylene, benzene can be obtained. These things can be obtained through chemical reaction, chemical products.Petroleum products can be divided into 6 categories: petroleum fuels, petroleum solvents and chemical raw materials, lubricants, paraffin, petroleum asphalt, petroleum coke and so on. Among them, the largest output of various fuels, accounting for about 90% of the total production of various lubricants; most varieties, production accounted for 5%. countries have developed a product standards, to meet the needs of production and use.gasoline
