Abstract
Description
Technical Field
[0001] This invention relates to the field of rare earth material fuel technology, and in particular to an alcohol fuel and its additives. Background Technology
[0002] Alcohol-based fuels are fuels primarily composed of alcohols. They exist in liquid or solid form. As a form of biomass energy, and like nuclear, solar, hydro, and wind power, they are environmentally friendly and clean energy sources that governments worldwide are actively promoting. Faced with the depletion of fossil fuels, alcohol-based fuels are the most promising new alternative energy source.
[0003] However, alcohol-based fuels are unstable in combustion, and their combustion efficiency needs to be improved. Currently, there is a lack of catalysts to reduce pollutant emissions, resulting in low combustion efficiency and large variations in combustion emissions. In particular, for fuels used in internal combustion engines of the power system involved, they cannot adapt well to the linear acceleration or motion of the internal combustion engine. In addition, existing alcohol fuel catalysts have single performance, large dosage, or poor temperature resistance, and there is a lack of methods to prepare relevant catalyst additives. The existence of all these problems seriously restricts the healthy and rapid development of alcohol-based fuels. Summary of the Invention

[0013] Figure 1 : for containing (C 28 H 42 Infrared spectrum of CuN2O3)n. Detailed Implementation
[0014] A rare earth compound catalyst for fuels, wherein the rare earth metal compound contains a hydroxyl group or a phenyl group or a C5-C group. 25 Groups, carboxyl groups, amine groups, or metal elements; the hydroxyl group, phenyl group, C5-C 25 Groups, carboxyl groups, amine groups, and metal elements containing the chemical formula (C 28 H 42 Substances containing MN2O3)n (where M represents a metal) or substances containing the following molecular structural formula I. .
[0015] The C5-C 25The group includes oleic acid, and the metal includes at least one or more of cerium, samarium, neodymium, terbium, dysprosium, zinc, copper, aluminum, platinum, palladium, rhodium, and ruthenium.
[0016] The following describes a substance containing (C) 28 H 42 The preparation method of substance MN2O3)n, where M represents a metal, is illustrated in the following examples using copper as the metal of M. 100g of N-(3-cyanophenyl)prop-2-enamide and copper oleate in a 1:1 molar ratio are dissolved in 2000g of xylene, an organic solvent. 0.5g of azodimethoxyisoheptanenitrile initiator is added. The solution temperature is raised to 50℃ or the solution becomes viscous to 3mPa·s, and then the reaction is carried out at a constant temperature of 50-70℃. During the reaction, the viscosity of the reaction solution is measured and maintained below 6mPa·s. After 8-12 hours of reaction, the solvent is evaporated, the solution is dried, and the solute is pulverized to form a target substance of approximately 100 mesh. A sample of this target substance is added to xylene at room temperature and tested for dissolution time; it dissolves within 30 seconds. Then, the KBr pellet coating method is used to pass the solution of the target substance in xylene through the coated film to obtain the infrared spectrum of the target substance (see [link to KBr pellet coating method]). Figure 1 ),Depend on Figure 1 It can be seen that the stretching vibration of the terminal olefin C=C bond in the reactant N-(3-cyanophenyl)prop-2-enamide occurs at 1640 cm⁻¹. - The significant weakening or disappearance of the peak near ¹ indicates that polymerization has occurred. After the carboxylate ion coordinates with the metal, its C=O stretching vibration peak changes, manifesting as a change in the peak value between 1590-1650 cm⁻¹. - ¹(Asymmetric stretching) and 1400-1450cm - ¹A broadened or split absorption band appears near (symmetric stretching), confirming the participation of copper oleate in the reaction, and at 1430 cm⁻¹ - ¹and 1550cm - The paired appearance of peaks indicates the symmetric stretching vibration of copper carboxylate, further suggesting a weakly cross-linked or complexly associated molecular structure at the carboxyl group position of the divalent copper ion, at 2200 cm⁻¹. - ¹ A clear cyano peak and 1670 cm⁻¹ - The strong amide carbonyl peak at 1870 cm⁻¹ is a key indicator of the successful incorporation of the N-(3-cyanophenyl)prop-2-enamide structural unit into the polymer. - ¹The strong aliphatic CH (-CH3,-CH2-) stretching vibrations in the vicinity primarily originate from the long alkyl chain and polymer backbone of copper oleate. 3000-3100cm - ¹The =CH stretching vibration on the nearby weak aromatic ring is a marker of the presence of the aromatic ring. Based on the above analysis, this preparation method produces at least one aromatic ring containing (C). 28 H 42CuN2O3)n or a substance containing the following molecular structural formula II was generated.
[0017] .
[0018] This application prepares a product containing (C) 28 H 42 CuN2O3)n or the generation of substances containing molecular structural formula II is a simple and convenient method.
[0019] Furthermore, including (C) 28 H 42 CuN2O3)n or substances containing molecular structural formula II are placed in a solution containing one or more metal ions selected from at least cerium, samarium, neodymium, terbium, dysprosium, zinc, aluminum, platinum, palladium, rhodium, and ruthenium. After adjusting the pH of the solution to 6-9 and adsorbing and chelating for 48 hours, substances containing (C) 28 H 42 CuN2O3)n or substances containing molecular structural formula II were generated by calcination, ashing, and acid dissolution. Atomic absorption spectrometry was then used to analyze the acid solution, revealing the presence of corresponding metal ions, indicating the presence of (C) 28 H 42 CuN2O3)n or substances containing molecular structure formula II have adsorption and chelation effects on the above-mentioned metal ions.
[0020] For those containing (C) 28 H 42 Temperature resistance test of CuN2O3)n or substances containing molecular structural formula II:
[0021] Take (C) 28 H 42 10g of CuN2O3 or a dry powder containing molecular structure II was dissolved in 200g xylene solution at room temperature. After stirring for 1 minute, the viscosity of the solution was measured to be 5.8 mPa·s using a six-speed rotational viscometer.
[0022] Temperature resistance performance comparison test, taking (C) 28 H 42 10g of a dry powder containing molecular structure II (CuN2O3)n was added to dimethyl silicone oil and stirred and heated to 200℃ for 5 minutes. Then, 10g of the dry powder was filtered out and dissolved in 200g of xylene solution at room temperature. After stirring for 1 minute, the viscosity of the solution was measured to be 5.8 mPa·s using a six-speed rotational viscometer. Therefore, it can be concluded that the dry powder contains (C... 28 H 42CuN2O3)n or substances containing molecular structure formula II have certain temperature resistance or adaptability to high temperatures. The above-mentioned substances containing benzene and cyano multi-branched structures are beneficial to the temperature resistance of the substances and can be used as long-lasting and stable catalysts or stable catalysts for fuel catalytic combustion.

The mixture was stirred and reacted evenly.
[0032] Example Effect Test: A sample of an alcohol fuel containing catalytic activity prepared in Examples 1-3 was taken and tested according to national standards, including calorific value. The CO emission and acceleration performance were tested using an engine. The acceleration performance test was conducted by adjusting the throttle of the internal combustion engine or engine from small to large (speed range 1500-2500 r / min) to see if the engine speed increased linearly.
