Problems solved by technology

But above-mentioned patent has following problem: in the freighter in ocean, due to low-speed operation, power performance will drop more than 30%, and fuel consumption increases about 30%; The decline of atomization quality leads to further deterioration of combustion conditions and the formation of a large amount of carbon deposits, which intensifies the wear of internal parts of the engine, reduces the lubricity of the engine, and causes a sharp shortening of the service life of the engine

Abstract

The invention discloses a production method of environment-friendly heavy clean fuel oil for ships, and belongs to the technical field of fuel oil processing. The production method of the marine fuel oil comprises the following steps: (1) pretreatment: preparing a fuel oil raw material, and safely storing the fuel oil raw material according to storage safety technical requirements of chemical products; (2) mechanical impurity removal treatment: filtering the fuel oil raw material stored in the step (1) to remove impurities; (3) mixing and homogenizing treatment: transferring the fuel oil raw material subjected to filtration and impurity removal in the step (2) into a homogenizing tank; and (4) standing reaction treatment: reacting the fuel oil raw material mixed and homogenized in the step (3) under the protection of nitrogen, standing, and cooling to room temperature. Tests show that the comprehensive performance of the marine fuel oil prepared by the invention can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fuel oil processing, and in particular relates to a production method of environment-friendly heavy clean marine fuel oil. Background technique [0002] With the continuous and high-speed development of social economy, my country's demand for petroleum products is also increasing. However, petroleum is a non-renewable energy source and is facing a crisis of depletion. In contrast, China has relatively abundant coal reserves, so producing liquid fuel from coal has become a basic direction of coal processing and utilization. On the other hand, with the rapid growth of the international and domestic steel industry, the coking industry is showing a high growth trend, the output of coal tar is increasing, and the clean processing and effective utilization of coal tar are becoming more and more important. [0003] At present, the conventional processing method is to cut various fractions with concentrated com...
