Kerosene:
Boiling point range of 180 ~ 310℃ is mainly used for lighting, cooking. The flame is required to be smooth and bright without black smoke, and the output is not large.
Petroleum bitumen:
It is mainly used for roads and buildings.
Petroleum coke:
Used as electrode in metallurgical (steel, aluminum), chemical (calcium carbide) industry.
Jet fuel:
Mainly used by jet aircraft.
Boiling point range of 60~280℃ or 150~315℃(commonly known as aviation gasoline and aviation kerosene). In order to adapt to the needs of high temperature and high speed flight, this kind of oil requires high calorific value and no solid crystallization at -50C.
Gasoline:
The most consumed species.
The boiling point of gasoline ranges from 30 °C to 205°C, and the density is 0.70 to 0.78 g/cc. Commercial gasoline is distinguished by the anti-knock combustion performance of the oil when burning in the cylinder, and is marked with octane number 70, 80, 90 or higher.
Label more than large, performance more than good, mainly used for cars, motorcycles, speedboats, helicopters, agriculture and forestry aircraft.
Diesel oil:
The boiling point range is 180~370℃ and 350~410℃.
For petroleum and its processed products, the low boiling point or boiling point range is traditionally called light, and the opposite is called heavy. Therefore, the former is called light diesel and the latter is called heavy diesel.
Commercial diesel oil is classified by freezing point, such as 10, 0, -10, -20, etc., indicating the applicable ambient temperature. Diesel oil is widely used in vehicles (including trains), ships and diesel boilers that use diesel internal combustion engines.
Because high-speed diesel engines are more fuel-efficient than gasoline engines, diesel demand is growing faster than gasoline, and some small cars are switching to diesel.
Petroleum solvent:
Refers to petroleum ether, 190#, 200# solvent oil.
Petroleum ether is divided into 30-60 degrees, 60-90 degrees, 90-120 degrees three, solvent oil to oil dry point for the brand, respectively for essence, grease, paint industry, reagent, rubber processing, coating industry solvent, or cleaning instruments, meters, mechanical parts.
Lubricating oil:
The lubricants derived from petroleum account for more than 95% of the total lubricant production.
In addition to lubrication performance, but also cooling, sealing, anti-corrosion, insulation, cleaning, transfer of energy. Commercial lubricating oil is classified by viscosity, high viscosity oil is used for machinery with large load and low speed, and low viscosity oil is used instead.
Refining unit production is to take a variety of refining technology made of base oil, plus a variety of additives, so it has special function, high additional output value.
Grease:
A solid or semi-fluid made of a lubricant thickener, used in bearings and gears where lubricating oil is not suitable.
Common calcium base and lithium base two, calcium base grease commonly known as butter, the largest dosage, the most widely used, suitable for most cases of equipment lubrication, lithium base grease is suitable for the use of relatively high temperature environment.
Paraffin oil:
Including paraffin wax (accounting for 10% of the total consumption), ground wax, petroleum grease, according to the use can be divided into industrial grade, cosmetic grade and food grade three.
Paraffin wax is mainly used as packaging materials, cosmetic raw materials and wax products, and can also be used as chemical raw materials to produce fatty acids (soap raw materials).
