Description
Technical Field
The invention relates to the technical field of marine fuel oil, in particular to low-sulfur marine fuel oil and a preparation method thereof.
Background
In recent years, the problem of air pollution caused by exhaust gas discharged from ships has received much attention from the international society. The International Maritime Organization (IMO) has strengthened the sulfur content limit for bunker fuels in overseas areas of global emission control, which has required that the upper limit of sulfur content for bunker fuels used in global ships be reduced from 3.5% to 0.5% since 2020. Thus, low sulfur bunker fuel oil refers to residual type fuels having a sulfur content of less than 0.5%. Currently, the global consulting agency forecasts the global low-sulfur marine residual fuel oil demand in 2020 to be 2.3-2.9 million tons, wherein the low-sulfur marine residual fuel oil demand accounts for 30%, and is about 7 million tons, and the market demand is large.
The blending component of the low-sulfur marine residual fuel oil mainly comprises residual oil fraction, and also comprises a diesel component (catalytic diesel), catalytic slurry oil and other components meeting the use, storage and transportation requirements. The catalytic slurry oil has higher sulfur content and carbon aromatic index, but has lower price, and is only about 1/4 of other low-sulfur marine fuel oil blending components; after treatment, the low-sulfur component is introduced to reduce the sulfur content and the carbon aromaticity index, so that more catalytic slurry oil can be added, and the production cost is reduced. Therefore, catalytic slurries are a low cost ideal blending component for low sulfur bunker fuel oils. CN110872533A discloses a low-sulfur heavy bunker fuel oil and a preparation method thereof, wherein the method is used for forming a bunker fuel by blending catalytic slurry oil according to the proportion of 5-15%. The catalytic slurry oil is low in adding proportion and relatively high in production cost. CN110205160A discloses a process method for preparing bunker fuel oil based on catalytic cracking slurry oil solidification and hydrogenation, which comprises the steps of mixing catalytic cracking slurry oil with a diluent, separating, deslagging, distilling to obtain solid-removed slurry oil, and then preparing a bunker fuel blending component by catalytic hydrogenation. The method needs to add toluene or petroleum ether solvent, and has high production cost.
