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

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 are indispensable in the entire transportation industry. Although ship transportation costs are 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 ship transportation. [0003] At present, the main fuels in ship transportation are light diesel oil and residual fuel oil (120, 180, 380 heavy oil), but light diesel oil is expensive nowadays; residual fuel heavy oil pretreatment is troublesome, high viscosity, high asphaltene content, high sulfur content, etc. Unfavorable factors make it severely wear marine diesel engines after use and the exhaust emissions seriously pollute the environment. In addition, global oil consumption is incr...
