Description
Technical Field
The invention relates to the field of fuel detergent, in particular to a detergent suitable for liquid fuel and a preparation method thereof.
Background
The automobile holding capacity of China is rapidly increased, and environmental pollution caused by burning and discharging of petrochemical fuels is not negligible. In the running process of an automobile, normal injection, atomization, mixing and combustion of oil materials can be seriously influenced by sediments generated in an air inlet system and a combustion chamber of an engine, so that the driving performance of the automobile engine is poor, the power and fuel economy are reduced, the emission is deteriorated, and the environment is damaged. At present, gasoline locomotives used in China, especially small cars, mainly use an electronic control fuel direct injection technology for engines. The application of this technology places higher demands on the quality of the fuel used. Because the olefin and part of heavy aromatics in the gasoline are easy to be oxidized and decomposed at high temperature, carbon deposit and colloid are further generated in the engine, the working condition of the engine is seriously influenced, and the power is reduced, the emission is increased and the oil consumption is increased. The fuel nozzle, intake valve and combustion chamber of the engine are the locations where deposits are most likely to form. How to reduce the carbon deposit of the engine, reduce the emission of the automobile exhaust and improve the economy of the oil product is the current research focus, so the research, the development and the application of the fuel detergent are very active.
Currently, the research on detergents can be roughly divided into four generations: the first generation originated from the last 60-70 years, mainly aiming at the deposits of a carburetor, and mainly comprising low-molecular amine compounds; in the second generation, in the 80-90 s, the main component of the fuel oil nozzle of the engine is polyisobutylene succinamide compounds; the third generation starts from the 90 s, has effects on air inlet valve caking and carbon deposition besides cleaning fuel nozzle deposits, and is mainly polyisobutylene amine and Mannich base ashless dispersant; the fourth generation is a detergent researched at present, namely a polyether amine compound, which has a cleaning effect on fuel nozzles and air inlet valves, and has the greatest progress of inhibiting and decomposing the generation of carbon deposit in a combustion chamber. The detergent represented by polyisobutene amine has excellent cleaning effect on fuel nozzles and intake valve carbon deposit, but is not easy to decompose, so that the generation of the carbon deposit in a combustion chamber is easy to increase; the polyether amine detergent has unique effect of inhibiting the carbon deposit in a combustion chamber, and has inferior cleaning effect on high-temperature parts compared with the third-generation detergent. Therefore, a detergent which has excellent cleaning capability on carbon deposit in a common area, has excellent cleaning effect on high-temperature parts and has excellent performance without increasing the harm of carbon deposit in a combustion chamber is needed.
Disclosure of Invention
In order to solve the above technical problems, the first aspect of the present invention provides a detergent for liquid fuel, which comprises at least, vegetable oil, fatty acid alkyl alcohol ester; an amino acid ester;
the total number of carbon atoms in the fatty acid alkyl alcohol ester is no more than 44.
In a preferred embodiment, the total number of carbon atoms in the fatty acid alkyl alcohol ester is 15 to 40.
As a preferred technical solution, the raw material further comprises cyclodextrin.
As a preferred technical scheme, the weight ratio of the fatty acid alkyl alcohol ester, the modified cyclodextrin and the vegetable oil is 1: (0.1-1): (2-6).
Preferably, the vegetable oil is selected from one or more of jojoba oil, nut oil, corn oil, soybean oil, palm oil, coconut oil, and castor oil.
Preferably, the saponification value of the palm oil is 180-189 mgKOH/g.
As a preferred technical proposal, the raw material also comprises a carrierThe carrier oil is white oil; the kinematic viscosity of the white oil is 9-51m2/s。
Preferably, the ratio of the vegetable oil to the carrier oil is 1 (0.5-2).
In a second aspect, the invention provides a method for preparing the detergent suitable for liquid fuel, which at least comprises the following steps:
(1) adding the vegetable oil and the amino acid ester into a reaction kettle, and uniformly mixing; (2) adding fatty acid alkyl alcohol ester, and stirring uniformly; (3) finally adding modified cyclodextrin, filtering by a 5-micron filter and discharging to obtain the product.
The foregoing and other features, aspects, and advantages of the present application will become more readily apparent with reference to the following detailed description.
