Embodiment 1

[0026] Shaanxi Shenmu low-temperature dry distillation coal tar was selected. Preliminary tests showed that its water content and mechanical impurity content were relatively high, so dehydration and mechanical impurity removal were pretreated first. The organic solvent selected during dehydration is toluene, and the solvent-to-oil ratio is 1:5, and placed in a distillation device at a temperature of 80° C. for 2 hours to remove excess water. Filtration is used to remove mechanical impurities.

[0027] Separate the Shenmu low-temperature dry distillation coal tar oil product after the above treatment, collect the above-water part and the underwater part respectively, measure their performance indicators, compare with the marine fuel oil standard (attached table 1), and determine the density as the most important factor affecting the quality of the blended oil. The main index of coal tar is to carry out the blending experiment of the above-water part and the underwater part of c...

Embodiment 2

[0030] Shaanxi Shenmu low-temperature dry distillation coal tar was selected, and the operation method and measurement results were the same as in Example 1, but the organic solvent selected during dehydration was petroleum ether.

Embodiment 3

[0032] Shaanxi Shenmu low-temperature dry distillation coal tar was selected, and the operation method and measurement results were the same as in Example 1, but the blending experiment of the above-water part and the underwater part of the coal tar determined that the blending mass ratio of the two was 20:80.

Abstract

The invention relates to a method used for producing bunker fuel oil by blending low-temperature carbonization coal tar. The method is to respectively measure the properties of the part over water and the part below water of the low-temperature carbonization coal tar, a blending experiment of the part over water and the part below water of coal tar is practiced according to the measurement result and bunker fuel oil standards and the main indexes of the blend oil are determined to obtain proper blending ration and polypropylene higher alcohols ester additive is added to get qualified bunker fuel oil.

Description

technical field [0001] The invention relates to the production of fuel oil, in particular to a method for producing marine fuel oil by utilizing low-temperature dry distillation coal tar through processing and blending. Background technique [0002] Fuel oil is mainly made of petroleum cracking residue and straight run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, colloids, and asphaltenes. According to the use, fuel oil is divided into two categories: fuel oil for marine internal combustion engines and fuel oil for furnaces. The former is a mixture of straight-run heavy oil and a certain proportion of diesel oil, which is used for large low-speed marine diesel engines; the latter is mainly made of vacuum residue, or cracked residue, or a mixture of the two, or by adding an appropriate amount of cracked light oil. Heavy petroleum fuel oil for various industrial furnaces or boilers as fuel. [0003] Marine fuel oil is usually...
