Abstract

The invention relates to a regulating method of fuel oil and particularly relates to a regulating method of bunker fuel oil. The bunker fuel oil is realized by the following process: naturally settling FCC (Fluid Catalytic Cracking) oil slurry and thermal-cracking residue oil, then, filtering by a filter screen to remove catalyst fine powder and other impurities contained in materials; pre-adding hydrogenation tail oil and ethylene bottom oil into a regulating tank, heating gradually, stirring until the two is uniformly mixed; adding the FCC oil slurry and the thermal-cracking residue oil treated in the step (1) into the regulating tank, increasing the temperature and uniformly mixing the components; adding a desulfurization aid, a cosolvent and combustion improver into the regulating tank in sequence, and uniformly mixing the components to obtain the product in the invention. According to the invention, the impurities and the catalyst fine powder in the FCC oil slurry and the residue oil easily cause severe corrosion and scale formation of an internal combustion engine, and the defect is improved by settling and filtering, so that emission of nitrogen oxides and SOx is lowered, and pollution on air and ocean is reduced.

Description

technical field [0001] The invention relates to a blending method of fuel oil, in particular to a blending method of marine fuel oil. technical background [0002] With the continuous and rapid economic development, China has become one of the world's most important trading and shipping countries, and it is also the country with the fastest growing demand for fuel oil in the world and is still accelerating. However, for a long time, due to the low output of ship fuel oil in domestic refineries and a large gap with market demand, ship fuel supply companies have to rely on imports, which is not conducive to the development of the shipping industry in the long run. [0003] Generally, marine fuel oil is mainly divided into two categories, namely distillate fuel oil and residual fuel oil. Distillate-type fuel oil is mainly suitable for medium-speed ship engines; while residual-type fuel oil is generally composed of heavy oil and light fractions. It has high calorific value, goo...
