Problems solved by technology

[0004] At present, the heavy marine fuel oil produced in the market has a sulfur content control index of 3.5%, which not only pollutes the environment, but also with the implementation of the sulfur limit policy, starting from 2020, the use of heavy marine fuel with a sulfur content exceeding 0.5% is prohibited oil, there is a need to provide a heavy bunker fuel oil with low sulfur content

Abstract

Low-sulfur heavy bunker fuel oil and a preparation method of same. The invention belongs to the technical field of heavy fuel oil. The low-sulfur heavy bunker fuel oil comprises, by weight, 40-65 parts of residual oil, 5-15 parts of catalytic oil slurry, 5-20 parts of styrene tar, 5-20 parts of ethylene tar, 5-20 parts of diesel oil, 0.2-1 part of an additive OP-10, and 0.1-0.5 parts of an additive AES. The preparation method includes: successively adding the styrene tar and diesel, the additive OP-10, the additive AES, the residual oil, and the catalytic oil slurry, and stirring the mixture at medium speed, and adding the ethylene tar and performing high-speed stirring to obtain the fuel oil. The invention solves the problems that the product is liable to generate flocs and to coke duringuse since the styrene tar cannot be uniformly blended with other oil products.

Description

technical field [0001] A low-sulfur heavy marine fuel oil and a preparation method thereof belong to the technical field of heavy fuel oil. Background technique [0002] The current marine fuel oil standard GB17411-2015 stipulates that when a ship sails in a general area of ​​the sea, the sulfur content of heavy marine fuel oil should not exceed 3.5%, and it should also meet the specific requirements of each port; with the increasing air pollution It is becoming more and more serious, and it is imminent to reduce pollutant emissions from ships. Measures to reduce pollutant emissions from ships include switching to low-sulfur fuel oil, increasing ship after-treatment devices, reducing ship speed, using alternative fuels, and establishing emission control areas. Among them, the use of low-sulfur fuel oil Fuel oil is the most effective and easiest first-choice measure to reduce pollutant emissions. [0003] The development of marine marine fuel oil is the same as that of vehic...
