Problems solved by technology

Low-sulfur and ultra-low-sulfur diesel generally adopt a harsh hydrogenation process. During the refining process of diesel, while removing sulfide, it also removes highly polar aromatic heterocyclic compounds, nitrogen-containing polar compounds and acidic substances, etc. Effective removal of anti-wear components, resulting in poor lubricity of diesel oil
This leads to excessive wear of fuel injection pumps such as rotary pumps and reciprocating pumps (In-line Pumps) that rely on diesel self-lubrication, which greatly reduces the service life of the fuel injection system
At the same time, there are also problems such as insufficient engine power, poor fuel atomization and fuel pump failure.

Embodiment 1

[0023] The low-sulfur diesel oil lubricant is made from the following raw materials in parts by weight (mixed uniformly): 40 parts of polyols, 30 parts of butyramide, 10 parts of triisoamylamine, and 1 part of vinyl butyl ether; The polyol is a mixture of diethylene glycol, triethylene glycol, and ethylene glycol in a weight ratio of 1:5:1.

[0024] Add 80 ppm of the lubricant of this example to the hydrorefined low-sulfur diesel oil, and measure the wear scar diameter according to the GB19147-2009 method to be 302 μm.

Embodiment 2

[0026] The low-sulfur diesel oil lubricant is made of the following raw materials in parts by weight (mixed uniformly): 80 parts of polyols, 15 parts of butamidine amide, 20 parts of triisoamylamine, and 10 parts of vinyl butyl ether; The polyol is a mixture of diethylene glycol, triethylene glycol, and ethylene glycol in a weight ratio of 2:4:1.

[0027] Add 100 ppm of the lubricant of this example to the hydrotreated low-sulfur diesel oil, and measure the wear scar diameter according to the GB19147-2009 method to be 308 μm.

Embodiment 3

[0029] The low-sulfur diesel oil lubricant is made from the following raw materials in parts by weight (mixed uniformly): 50 parts of polyols, 25 parts of butyramide, 12 parts of triisoamylamine, and 8 parts of vinyl butyl ether; The polyol is a mixture of diethylene glycol, triethylene glycol, and ethylene glycol in a weight ratio of 6:2:1.

[0030] Add 120 ppm of the lubricant of this example to the hydrotreated low-sulfur diesel oil, and measure the wear scar diameter according to the GB19147-2009 method to be 311 μm.

Abstract

The invention belongs to the technical field of fuel, and particularly relates to a low-sulfur diesel oil lubricant, which is made of the following raw materials in parts by weight: 40-80 parts of polyol, 15-30 parts of butyramide, 10-20 parts of triisoamylamine, ethylene 1-10 parts of methyl butyl ether. The low-sulfur diesel lubricant of the present invention enables low-sulfur diesel oil to have a good lubricating effect without affecting the performance of the diesel oil. When added to the low-sulfur diesel oil, it can adapt to various diesel engines.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a low-sulfur diesel oil lubricant. Background technique [0002] From January 1, 2018, national automotive diesel will implement the national standard, requiring the mass fraction of sulfur to be less than 10 μg / g. Low-sulfur and ultra-low-sulfur diesel generally adopt a harsh hydrogenation process. During the refining process of diesel, while removing sulfide, it also removes highly polar aromatic heterocyclic compounds, nitrogen-containing polar compounds and acidic substances, etc. Effective anti-wear components are removed, resulting in poor lubricity of diesel oil. This leads to excessive wear of fuel injection pumps such as rotary pumps and reciprocating pumps (In-line Pumps) that rely on diesel self-lubrication, which greatly reduces the service life of the fuel injection system. At the same time, there are also problems such as insufficient engine power, poor fuel atomiza...
