Problems solved by technology

[0002] In recent years, fuel stabilizers have been widely used in fuels to improve the oxidation resistance and thermal oxidation stability of fuels, but their matching and compatibility with other additives in fuels have not been effectively improved, which may easily lead to deterioration of fuel performance. decline, even chemical precipitation
[0003] For example, the domestic patent CN1317372C discloses the proportion and composition of a nano-fuel additive. This patent is the closest technology to this technology. The compatibility and stability of the agent still need to be improved

Embodiment Construction

[0017] The apparatus used in the present invention will be well understood to those skilled in the art.

[0018] Components and weight percentages of the present invention are as follows:

[0019] Rare earth oxide powder 0.1-2% (one or more of the lanthanide metal oxides with a particle size between 50-150 nm);

[0020] Fuel synergist 10-40% (JM-1 fuel synergist produced by Shanghai Jineng Chemical Co., Ltd., because its components are metal oil-soluble rare earth compounds of calcium and cerium, which account for about 5% of the fuel synergist and The mixture composed of 95% white oil plays an auxiliary role in the dispersion of rare earth nanopowders);

[0021] Rare earth stearate 1-15%;

[0022] Rare earth naphthenate 1-15%;

[0023] Di-tert-butylphenol 1-15%;

[0024] Di-tert-butyl-p-cresol 1-15%;

[0025] Dispersant 1-30% (one or more of calcium naphthenate with high base value, barium polyisobutene sulfur phosphate, and monoalkenyl succinimide);

[0026] Balance: h...

Abstract

The invention relates to the technical field of fuel thermal stabilizer, in particular to a fuel oil storage stabilizer with good compatibility and a preparation method thereof. The stabilizer comprises the following components by weight percentage: 0.1 to 2 percent of rare earth oxide, 10 to 40 percent of fuel oil synergist, 1 to 15 percent of rare earth stearate, 1 to 15 percent of rare earth naphthenates, 1 to 15 percent of di-tert-butylphenol, 1 to 15 percent of butylated hydroxytoluene, 1 to 30 percent of dispersant, and the balance of hydrogenated white oil, wherein the rare earth oxide adopts one or more lanthanide series metal oxide with the particle diameter being 50 to 150 nanometers. The stabilizer adopts the multi-coordinate linkage properly of rear earth, the surface activity of nano-powder and the unique micro-scale and macro-scale characteristics of the nano-powder, thereby greatly improving the stability of fuel oil, and simultaneously greatly enhancing the compatibility of other addition agent in the fuel oil, and being widely applied to the preparation of various fuel oil.

Description

[technical field] [0001] The invention relates to the technical field of fuel heat stabilizers, in particular to a fuel storage stabilizer with good compatibility and a preparation method thereof. [Background technique] [0002] In recent years, fuel stabilizers have been widely used in fuels to improve the oxidation resistance and thermal oxidation stability of fuels, but their matching and compatibility with other additives in fuels have not been effectively improved, which may easily lead to deterioration of fuel performance. decline, and even chemical precipitation occurs. [0003] For example, the domestic patent CN1317372C discloses the proportion and composition of a nano-fuel additive. This patent is the closest technology to this technology. The compatibility problem and the stability problem of the agent still need to be improved. [Content of the invention] [0004] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior a...
