Description

Technical Field

[0001] The invention relates to the technical field of ship fuel auxiliary combustion, and in particular to a ship fuel enhancer and a preparation method thereof. Background Art

[0002] Traditional ship fuels produce a large amount of greenhouse gases, nitrogen oxides, sulfur oxides and particulate matter when burned, causing serious pollution to air quality and aggravating global climate change.

[0003] Traditional marine fuel is made of atmospheric residue oil produced by atmospheric distillation and vacuum residue oil produced by vacuum distillation through a desulfurization process to make residual oil fuel. Generally, the sulfur content, colloid and asphaltene content of atmospheric and vacuum residue oils are high. Therefore, in order to meet the requirements of the International Maritime Organization for marine fuel and emissions, ship oil companies often mix low-sulfur distillate oil (CLO) and tail oil produced in the process of crude oil catalytic cracking (FCC) with atmospheric and vacuum residue oil to blend into marine fuel of the required quality. In recent years, with the increasing shortage of oil resources, people pay more attention to the full utilization of petroleum products. In order to increase the yield of light fractions, refineries have adopted new processes and technologies to increase the depth of refining processing, which is bound to lead to a decline in the quality of marine fuel oil. At present, marine fuel oil faces a series of problems such as high aromatic content, poor combustion characteristics, poor ignition performance, high pollutant emissions, and easy formation of carbon deposits in the engine by combustion products.

[0004] In response to the above problems, existing fuel additive related technologies are mostly applied to gasoline, light diesel, aviation kerosene and other fields, such as publication number: CN113174277A, a fuel additive that can improve the combustion efficiency of high-clean gasoline, adding a combustion aid with methanol, ethanol and other ingredients as the main components, solving the problem of low gasoline combustion efficiency. However, compared with the physical properties, chemical composition and combustion characteristics of ship fuel and light fuel, the composition and proportion of the ship's fuel enhancer should take into account the boiling point, volatility, combustion time and other characteristics of heavy fuel to review the above technical defects and prepare fuel additives for ships.

[0005] In view of the above problems, it is necessary to provide a marine fuel oil additive to improve the combustion efficiency of marine fuel oil, reduce the carbon deposit content, and reduce the emission of pollutants during the combustion process. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a marine fuel enhancer and a preparation method, the purpose of which is to solve the following problems: promoting the complete combustion of marine fuel, reducing the emission of harmful substances such as carbon monoxide, hydrocarbons, nitrogen oxides and particulate matter, and effectively removing and inhibiting carbon deposition problems in engine intake valves, fuel injectors, combustion chambers and other parts.
