preparation example Construction

[0042] The present invention also provides a method for preparing the above lubricating and antifriction additive for aviation biofuels, the steps of which include: mixing the antifriction agent and the lubricant according to the ratio at a reaction temperature of 15-35°C and a reaction pressure of 1 standard atmosphere Then add it into the organic solvent and mix it again, or add the wear reducer and lubricant into the organic solvent separately according to the ratio and mix it thoroughly.

[0043] The present invention also provides an application of the above-mentioned lubricating and anti-friction additive for aviation biofuel, specifically: adding the above-mentioned lubricating and anti-friction additive to aviation biofuel, petroleum-based aviation kerosene or both at a ratio of 10-100 μg / g It is uniformly dispersed in the aviation kerosene fuel formed by blending.

Embodiment a

[0045] A kind of lubricating anti-friction additive for aviation biofuel, comprising lubricant, anti-friction agent and organic solvent, the mass ratio of lubricant and anti-friction agent is 1:1 (that is, lubricant (mass): anti-friction agent (mass) = 1:1), the mass ratio of organic solvent and the mixture formed by lubricant and antifriction agent is 0.5:1 (that is, organic solvent (mass): mixture formed by lubricant and antifriction agent ( mass) = 0.5:1);

[0046] The lubricant is methyl oleate, an ester of carboxylic acid; the antifriction agent is tri-n-butyl borate, an ester of boric acid; the organic solvent is aromatic hydrocarbon; the aviation biofuel is Vegetable oils are used as raw materials, and paraffin distillate oils are synthesized by hydrogenation of oils.

[0047] The lubricating anti-friction additive for aviation biofuels of this embodiment can be used simultaneously with antistatic agents, antioxidants, anti-icing agents, preservatives, metal deactivato...

Embodiment b

[0051] A kind of lubricating antifriction additive for aviation biofuel, comprising lubricant, antifriction agent and organic solvent, the mass ratio of lubricant and antifriction agent is 5:1 (that is, lubricant (mass): antifriction agent (mass) = 5:1), the mass ratio of the mixture of organic solvent and lubricant and antifriction agent is 0:1 (that is, organic solvent (mass): mixture of lubricant and antifriction agent ( Quality)=0:1, that is, no organic solvent is added);

[0052] The lubricant is an amide compound oleic acid amide; the friction reducer is triisobutyl phosphate, a phosphoric acid ester; the aviation biofuel uses agricultural and forestry waste as raw materials, and utilizes biomass gasification - Paraffin distillates synthesized by Fischer-Tropsch synthesis technology.

[0053] The lubricating anti-friction additive for aviation biofuels of this embodiment can be used simultaneously with antistatic agents, antioxidants, anti-icing agents, preservatives, m...

Abstract

The invention discloses a lubricating and anti-friction additive for aviation biofuel, which comprises a lubricant, an anti-friction agent and an organic solvent. The mass ratio of the lubricant to the anti-friction agent is 1-5:1, and the organic solvent and the lubricant and The mass ratio of the mixture formed by the antifriction agent is 0-0.5:1; the lubricant is a carboxylic acid ester compound or an amide compound; the antifriction agent is a boric acid ester compound or a phosphoric acid ester compound or organic molybdenum compounds. The invention can improve the problem that the aviation biofuel has poor lubricity during use and easily causes wear of the engine oil pump and related flow control elements.

Description

technical field [0001] The invention relates to aviation biofuel additives, in particular to aviation biofuel additives with lubricating and anti-friction functions. Background technique [0002] At present, the global aviation transportation industry consumes 1.5 to 1.7 billion barrels of aviation kerosene every year, all of which come from fossil energy—petroleum. Although the carbon dioxide produced by aviation kerosene only accounts for 3% of all human emissions, the nitrogen oxides, carbon oxides and other substances produced by the combustion of aviation kerosene are directly emitted into the high altitude, which thickens the ozone layer that absorbs ultraviolet rays and creates greenhouses. The ability and harm of air pollution effects are far greater than those of other industries, and the pollution produced by air traffic has become a factor that cannot be ignored in causing global warming. In order to reduce carbon dioxide greenhouse gas emissions, the Internation...
