Problems solved by technology

The hydrocarbons contained in diesel oil have high carbon content and high combustion power, but these properties also prevent diesel oil from being fully combusted and emit a large amount of harmful exhaust gas. massive loss of energy
[0003] In order to reduce the fuel consumption and pollution of diesel vehicles, adding diesel additives is the most convenient and direct method. At present, there are many kinds of diesel additives, but in general, the existing common diesel additives have single performance, which can improve combustion value, deal with carbon deposits, reduce pollutants, The performance of reducing energy consumption is not ideal; the multi-functional composite diesel detergent has a good cleaning effect on nozzles and intake valve carbon deposits, but is not ideal for cleaning carbon deposits in combustion chambers
[0004] CN1986751A discloses a multifunctional diesel detergent, which is composed of polyisobutylene succinimide, boronized ashless dispersant, polyether amine, alkyl rare earth, and alkyl ester, which can promote the full combustion of fuel and have smoke-eliminating properties. Oil effect, has cleaning effect on nozzle and oil supply system, but its effect on carbon deposit in combustion chamber is not obvious
[0005] CN1080315A discloses a diesel detergent, including metal organic acid salts, emulsifiers and alcohols, which can easily lead to increased carbon deposits in the combustion chamber, and the emulsification of diesel oil

preparation example Construction

[0053] The preparation method of above-mentioned compound type diesel oil energy-saving cleaner comprises the following steps:

[0054] First, in the reactor, the organic acid is saponified into a transparent homogeneous liquid by aqueous sodium hydroxide solution; the mass fraction of the aqueous sodium hydroxide solution is 20-40%, and the mass ratio of the organic acid to the aqueous sodium hydroxide solution is (6-8): 1;

[0055] Then react with rare earth brine solution at 60-90°C for 30-60min, separate the liquid and take the upper layer for refining to obtain organic acid rare earth; the mass fraction of rare earth brine solution is 30-50%, and the mass ratio of organic acid to rare earth brine solution is ( 6-8): (9-10);

[0056] Finally, take 1-3 parts of organic acid rare earth, add 30-60 parts by mass of dispersant, 30-60 parts of nitrate, 2-4 parts of antioxidant, and 3-10 parts of Mannich base to mix evenly, and the obtained product is a compound Type diesel ene...

Abstract

The invention relates to a composite diesel energy-saving detergent and a preparation method thereof; the preparation method comprises; first, saponifying, in a reactor, an organic acid into a transparent homogeneous liquid via sodium hydroxide solution; second, reacting with rare-earth saline solution, allowing separation, collecting supernate, and refining to obtain organic acid rare earth; third, adding a dispersant, nitrate, an antioxidant and Mannich base to the organic acid rare earth, and mixing well to obtain the product, the composite diesel energy-saving detergent. The composite diesel energy-saving detergent has a high content of effective ingredients and has good diesel solubility and deterging dispersibility, the preparation method is environmentally friendly and safe, and the composite diesel energy-saving detergent and the preparation method thereof have significant market advantages.

Description

technical field [0001] The invention belongs to the technical field of diesel oil detergent preparation, and in particular relates to a compound energy-saving diesel oil detergent and a preparation method thereof. Background technique [0002] With the widespread use of large diesel machinery and diesel vehicles, the consumption of diesel is increasing year by year. The hydrocarbons contained in diesel oil have high carbon content and high combustion power, but these properties also prevent diesel oil from being fully combusted and emit a large amount of harmful exhaust gas. A large loss of energy. [0003] In order to reduce the fuel consumption and pollution of diesel vehicles, adding diesel additives is the most convenient and direct method. At present, there are many kinds of diesel additives, but in general, the existing common diesel additives have single performance, which can improve combustion value, deal with carbon deposits, reduce pollutants, The performance of...
