Embodiment 1

[0025] A kind of embodiment of the present invention, the preparation method of the low-sulfur marine fuel oil described in the present embodiment, comprises the steps:

[0026] (1) Heat the catalytic oil slurry, isononyl alcohol heavy oil, and residual oil to 60°C respectively;

[0027] (2) Mix catalytic oil slurry and isononyl alcohol heavy oil evenly, heat and stir to obtain mixture A;

[0028] (3) Add residual oil into mixture A, heat and stir, the temperature of heating and stirring is 60° C., the time of heating and stirring is 60 min, and the speed of heating and stirring is 500 rpm; the low-sulfur marine fuel oil is obtained.

[0029] The preparation methods of the examples and comparative examples of the present invention are exactly the same as those of Example 1, and the mixing efficiency and mixing effect can be ensured within the allowable heating temperature, heating time and speed range of the present invention.

[0030] Simultaneously, the present invention se...

Abstract

The invention discloses low-sulfur marine fuel oil and a preparation method thereof, and relates to the technical field of marine fuel oil. The invention provides low-sulfur marine fuel oil, which comprises the following components: residue oil, catalytic slurry oil and isononyl alcohol heavy oil. The invention provides low-cost and low-sulfur marine fuel oil, which has the characteristic of low sulfur content, and meets increasingly strict environmental protection requirements. According to the invention, a proper amount of isononyl alcohol heavy oil component is added, so that the problem that a large amount of cheap catalytic slurry oil cannot be added due to high sulfur content and carbon aromaticity index is solved, and the production cost can be reduced; and isononyl alcohol heavy oil has the characteristics of low sulfur content and low carbon aromaticity index, and the price of the isononyl alcohol heavy oil is lower than that of a hydrogenated diesel oil component by more than 60%, so that the production cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of marine fuel oil, in particular to a low-sulfur marine fuel oil and a preparation method thereof. Background technique [0002] In recent years, the problem of air pollution caused by exhaust exhaust from ships has attracted widespread attention from the international community. The International Maritime Organization (IMO) has strengthened the sulfur content limit for marine fuel oil in sea areas outside the global emission control area, requiring that the sulfur content limit of fuel oil used by global ships be reduced from 3.5% to 0.5% from 2020. Therefore, low-sulfur marine fuel oil refers to residual fuel with a sulfur content of less than 0.5%. At present, the world consulting agency predicts that the global demand for low-sulfur marine residual fuel oil in 2020 is roughly 230 million to 290 million tons, of which the demand for low-sulfur marine residual fuel oil accounts for 30%, about 70 million ...
