Problems solved by technology

At the same time, the advantages of the three have their own merits. Adsorption desulfurization technology can achieve ultra-deep desulfurization. Once the sulfur concentration increases, and when faced with some special sulfide components, such as thiophene, benzothiophene, dibenzothiophene and other Derivatives and other heterocyclic sulfide components will greatly increase energy consumption, which is not conducive to the economic benefits of enterprises; oxidation desulfurization technology and extraction desulfurization technology have low energy consumption and good economic benefits. The higher the sulfur content, the more significant the economic benefits. However, due to the fact that the objective production conditions are difficult to ensure the depth and thoroughness of the oxidation reaction and extraction reaction, it is difficult to achieve ultra-deep desulfurization by oxidation desulfurization technology and extraction desulfurization technology

Description

technical field [0001] The invention belongs to the field of vehicle fuel oil, and relates to a complete set of ultrasonic-assisted vehicle fuel linkage desulfurization system, and also relates to an ultrasonic-assisted vehicle fuel linkage desulfurization method. Background technique [0002] With the increasingly stringent environmental protection regulations, ultra-low sulfuration and high cleanliness of vehicle fuel is the general trend. my country has formulated and promulgated the "National V" standard for fuel oil, which stipulates that the sulfur content index in vehicle fuel oil shall not exceed 10ppm, that is, less than or equal to 10 parts per million; it has been implemented on a trial basis since 2015 and will be fully implemented in 2017. This means that the era of ultra-low sulfuration and high cleanliness of vehicle fuel in my country is coming. Therefore, it is imperative to improve vehicle fuel desulfurization technology. [0003] At present, the most com...
