Problems solved by technology

[0003] At present, the main fuel in ship transportation is light diesel oil and residual fuel oil (120, 180, 380 heavy oil), but the price of light diesel oil is expensive now; the pretreatment of residual fuel heavy oil is troublesome, with high viscosity, high asphaltene content and high sulfur content. Unfavorable factors make it severely wear and tear on marine diesel engines after use and the exhaust gas seriously pollutes the environment. In addition, the global oil consumption continues to increase, its processing and development capabilities are limited, and it is not renewable, it is difficult to meet the current marine fuel oil market

preparation example Construction

[0018] According to the preparation method of fuel oil of the present invention, the method comprises raw materials by weight: 60-80 parts of base oil, 5-30 parts of kerosene, 5-20 parts of light diesel oil, 0.1-1 part of cetane number improver, 0.05 ~0.2 parts of low temperature flow improver and 0.01~0.1 parts of high-efficiency composite additives, of which,

[0019] The method comprises the following operations: centrifuging the base oil after stirring, cooling, and crystallization; Oil is mixed thoroughly.

[0020] Among them, the base oil is preferably washing oil; in addition, the base oil may also preferably be a mixture of 50-80 parts of anthracene oil and 20-50 parts of washing oil. Among them, anthracene oil is a part of coal tar components, and the distillate of 280-360 degrees is collected by distilling tar; washing oil is the fraction of coal tar with a boiling range of 230-300 degrees. The washing oil can be used alone as base oil to prepare fuel oil, or the w...

Abstract

The invention discloses a preparation method of fuel oil. The fuel oil is prepared from the following raw materials, by weight, 60-80 parts of base oil, 5-30 parts of kerosene, 5-20 parts of light diesel fuel, 0.1-1 part of a cetane number improver, 0.05-0.2 part of a cold flow improver and 0.01-0.1 part of an efficient composite additive. The preparation method comprises the following operations: base oil undergoes stirring, cooling, crystallization and centrifugation; and kerosene, light diesel fuel, the cetane number improver, the cold flow improver and the efficient composite additive are fully mixed with the base oil. The invention also discloses fuel oil. The fuel oil prepared by the above method is applied to steamships and has advantages of high cetane number, good low-temperature starting performance, strong break-out force, low cost and wide source of raw materials. In addition, the preparation technology is simple.

Description

technical field [0001] The invention relates to a fuel oil, in particular to a fuel oil and a preparation method thereof. Background technique [0002] Ship transportation has large capacity, low cost and long transportation distance, which is indispensable in the entire transportation industry. Although the cost of ship transportation is low, fuel costs account for about 60% of the entire transportation cost. With the rapid rise of international oil prices, reducing fuel costs has become the key to shipping. [0003] At present, the main fuel in ship transportation is light diesel oil and residual fuel oil (120, 180, 380 heavy oil), but the price of light diesel oil is expensive now; the pretreatment of residual fuel heavy oil is troublesome, with high viscosity, high asphaltene content and high sulfur content. Unfavorable factors make it severely wear and tear on marine diesel engines after use and the exhaust gas seriously pollutes the environment. In addition, the glob...
