preparation example Construction

[0013] The preparation method of described marine fuel oil provided by the invention comprises the following steps:

[0014] (1) Visbreaking the heavy oil component at 400-450°C for 10-60 minutes;

[0015] (2) Fractionate the product obtained after visbreaking, and collect fractions with a distillation range higher than 165°C;

[0016] (3) Mix the fraction with a distillation range higher than 165°C with the light oil component to obtain a density of 850-991kg / m at 15°C 3 、The viscosity at 50℃ is not more than 380mm 2 / s and bunker fuel oil with a total content of 0-80 mg / kg of silicon calculated as silicon element and aluminum calculated as aluminum element.

[0017] In the present invention, the 100°C viscosity of the heavy oil component is not less than 35mm 2 / s, preferably 35-60mm 2 / s; 15°C density is 950-1200kg / m 3 , preferably 950-1050kg / m 3 ; The total content of silicon in terms of silicon and aluminum in terms of aluminum is 0-300 mg / kg, prefer...

Embodiment approach

[0025] According to one embodiment of the present invention, the schematic diagram of the implementation equipment and material flow direction of the bunker fuel oil can be as follows figure 1 shown. exist figure 1 Among them, the heavy oil component 1 enters the heating furnace 3 through the heat exchanger 2 to heat up, and the temperature of the heavy oil component is controlled to 400-450°C (preferably 410-430°C), and then the heavy oil component is reheated at this temperature The high-quality oil component is added to the upflow reactor 4 for visbreaking treatment for 10-60 minutes; then, the product of the visbreaking reaction is added to the fractionation tower 5 for fractionation, and the distillation range is higher than 165°C collected from the bottom of the tower The distillate, so that the distillate with a distillation range below 165°C is extracted from the top of the tower; then, the distillate with a distillation range higher than 165°C is added to the blendin...

Embodiment 1

[0030] This example is used to illustrate the bunker fuel oil and its preparation method provided by the present invention.

[0031] The vacuum residue (see Table 1 for performance parameters) was visbroken at 430°C for 30 minutes, and the obtained product was added to a fractionation tower for fractionation, and fractions with a distillation range higher than 165°C were collected from the bottom of the tower, and Add 82 parts by weight of the fraction higher than 165°C in the blending tank, and add 2.5 parts by weight of catalytic cracking oil slurry (see Table 1 for performance parameters) and 15.5 parts by weight of catalytic cracking oil slurry in this blending tank Crack diesel oil (see Table 1 for performance parameters) to obtain 180CST marine fuel oil, the performance parameters of which are shown in Table 2 below.

Abstract

The invention discloses a preparation method of marine fuel oil, comprising the following steps: (1) visbreaking heavy oil components at 400-450 DEG C for 10-60 min; (2) carrying out fractionation on the product obtained by visbreaking, and collecting fractions with the distillation range of higher than 165 DEG C; and (3) mixing the fractions with the distillation range of range of higher than 165 DEG C and light oil components to obtain the marine fuel oil which is characterized in that the density at 15 DEG C is 850-991 kg/m<3>, the viscosity at 50 DEG C is no larger than 380 mm<2>/s, the total content of silicon measured as silicon and aluminium measured as aluminium is 0-80 mg/kg, wherein the viscosity of the heavy oil components at 100 DEG C is no less than 35 mm<2>/s, the density of the heavy oil components at 15 DEG C is 950-1200 kg/m<3>, and the total content of silicon measured as silicon and aluminium measured as aluminium in the heavy oil components is 0-300 mg/kg The invention also provides the marine fuel oil prepared by the method. According to the method of the invention, the production cost of the marine fuel oil can be greatly reduced.

Description

technical field [0001] The invention relates to a method for preparing marine fuel oil and marine fuel oil prepared by the method. Background technique [0002] With the sustained and rapid economic development, China has become one of the world's most important trading and shipping countries. Facing the booming shipping and marine oil market, for a long time due to the low output of marine fuel oil in domestic refineries and a large gap with market demand, marine oil supply companies and shipping companies have to rely on imports and are forced to accept high demand from the international market. Oil prices and market risks will not be conducive to the development of the shipping industry in the long run, and will also have a negative impact on foreign trade and national economic development. [0003] Generally, marine fuel oil is mainly divided into two categories, namely distillate fuel oil and residual fuel oil. Distillate fuel oil is widely used in China, such as DMC,...
