Description

Technical Field

[0002] With the continuous maturity of automobile industry technology, the number of fuel-burning motor vehicles is increasing day by day. Exhaust emissions are becoming more and more serious. The main source of environmental pollutants is the engine exhaust of fuel-burning motor vehicles. Exhaust emissions from fuel vehicles account for more than 30% of environmental pollutants. These exhausts contain a large amount of harmful gases and inhalable particulate matter such as sulfides, nitrides, carbon, and lead. These exhaust emissions are distributed in the air 0.5 to 3 meters above the ground, seriously polluting the living environment of human beings and threatening human health.

[0003] In order to achieve the goal of "carbon peak and carbon neutrality", we should first start from the field of science and technology and vigorously develop technologies and measures for environmental governance. We should solve the bottleneck technologies of environmental governance, energy conservation and emission reduction, innovate and develop key products, and intensify efforts to promote clean, environmentally friendly, energy-saving and emission reduction industries.

[0004] In order to control the harm caused by exhaust emissions of fuel vehicles to the environment and humans, many countries in the world have formulated increasingly stringent exhaust emission standards and regulations for fuel vehicles. Installing a three-effect purifier and an electronic injection closed-loop controller on the exhaust system of fuel vehicles is one of the effective measures to solve automobile exhaust pollution. However, most of these devices can only purify particulate media, and have little effect on purifying carbon monoxide and hydrocarbon gases, and cannot play a very effective purification role. In order to better achieve the purification of fuel vehicle exhaust to meet the latest national six and Beijing six standards, in view of the phenomenon of excessive exhaust emission pollutants from fuel vehicles on the market and the stubborn problem of environmental pollution control, through years of research and experiments, the present invention summarizes a clean and environmentally friendly biofuel-diesel alternative fuel and its preparation method.

[0046] The physicochemical properties and effects of each raw material in the present invention are briefly described as follows:

[0047] Isooctyl nitrate: It can increase the cetane number of diesel, improve the combustion performance of diesel, shorten the ignition time, reduce the ignition point, improve the thermal power of locomotives, and save fuel significantly. Application: It is used in diesel fuel, especially in secondary processed diesel to increase its cetane number. The effect of addition varies depending on the base oil. Generally, adding 0.1%-0.3% of isooctyl nitrate can increase the cetane number by 2-9 units. It can also be used as an organic solvent. It is used in the present invention to improve the combustibility and anti-explosion properties.

[0048] Diisopropyl ether: It is miscible in most organic solvents such as alcohol, ether, benzene, chloroform, etc. It has the function of being compatible with various formulation components in the present invention.

[0049] n-Octanol: It is a colorless flammable liquid with a special odor, which is miscible with most organic solvents. In the present invention, it is miscible with the auxiliary agents of each component, and can be called a highly compatible combustion aid.

[0050] High carbon number fatty alcohol: easily soluble in organic solvents such as n-butanol, isopropanol, ether, chloroform, ethanol, benzene, petroleum ether, cyclohexane, acetone, methanol, etc. It can be mixed with polyoxymethylene dimethyl ether to form the best multi-soluble solvent.

[0051] Polymethoxy dimethyl ether: It is a clean fuel. In the present invention, it can improve the lubrication performance of oil products, has good miscibility with fuel oil, and is very suitable as a diesel additive component. Polymethoxy dimethyl ether has a relatively high oxygen content, which can reach up to 51% at most, and an average cetane number of 76, which can improve the combustion efficiency of diesel in the engine. When added to diesel, it can significantly reduce pollutant emissions, reduce sulfide, CO and NOx emissions, and reduce tail gas pollution. Polymethoxy dimethyl ether is currently the best environmentally friendly solvent in the field of solvents. It is a very clean and environmentally friendly solvent oil that is sulfur-free, aromatic-free, benzene-free, and chlorine-free. As a solvent mother liquor, it has alcohol-soluble, ether-soluble, and fat-soluble multi-solubility and compatibility. It is currently the world's best universal solvent and an important component for diesel addition and replacement.

[0052] Fischer-Tropsch wax: Fischer-Tropsch wax is a methylene polymer, an alkane polymer synthesized from hydrocarbon-based syngas or natural gas. It mainly relies on high-quality and cheap raw materials from coal chemical industry for iron-based or cobalt-based synthesis. It is one of the base oils for formulating biofuel-diesel alternative fuel.

[0053] Castor oil: Castor oil is a vegetable oil with good lubricating properties. It can reduce friction and wear between mechanical parts and extend the service life. Castor oil contains more unsaturated fatty acids, which can be used as a rust inhibitor to protect the metal surface and prevent metal oxidation and corrosion. It has high drying and weather resistance, and can enhance the adhesion and durability of coatings and paints. Castor oil can also be used as a solvent, and the polyunsaturated fatty acids in castor oil can be used as additives for oil products. It can improve the softness, ductility and toughness of oil products and improve their service life. Castor oil can be used as a raw material for biofuel. Due to its high unsaturated fatty acid content, castor oil methyl ester is used as a diesel substitute. It is used as a biological raw material in the present invention.

[0054] Glycerol of kuehne acid: It is a saturated fatty acid ester, a special diluent, emulsifier stabilizer, solubilizer and preservative. It is colorless, odorless, transparent, has good stability and is durable in storage. It is used as a biological raw material in the present invention.

[0055] Mixed alcohol: It is a synthetic modifier using polymethoxy dimethyl ether as solvent. Propane, butane and methanol are mixed in a certain proportion to make methanol physically react and change its alkalinity. After the synthetic denaturant physically reacts with the molecular structure of methanol, a new molecular structure chain is formed under the action of polymethoxy dimethyl ether molecules, which effectively inhibits the secondary acid discharge of methanol during combustion, so that the acid is completely physicochemically transformed during combustion. Mixed alcohol has the advantages of cleanliness and environmental protection, safety and anti-explosion, strong power, low energy consumption rate, good versatility, low corrosiveness and low price. Thus, the purpose of modifying methanol raw materials is achieved. The corrosiveness of oil products to engines is greatly reduced.

[0056] Diisoamyl oxalate: It is a new type of diesel cetane number improver. It has obvious advantages in replacing traditional nitrate additives. It does not produce nitrogen oxides (NOx) when burned, does not corrode equipment, does not pollute the environment, and meets the requirements of environmentally friendly products. In the present invention, it is used to improve the octane number, promote combustion, and eliminate smoke, especially when mixed with isooctyl nitrate, the effect is better.

[0057] 2-Ethylhexyl nitrate: Cetane number improver, a class of compounds that easily decompose free particles, so it can accelerate the speed of the chain reaction when diesel fuel is ignited. It can promote the rapid oxidation of diesel, so it can improve the ignition characteristics of diesel. It can increase the chain initiation rate of diesel during the combustion process. It promotes the rapid oxidation of diesel and improves its ignition performance. At the same time, it is also the most economical and effective important component for improving tail gas emissions.

[0058] Sodium dodecyl sulfate: It is easy to biodegrade, with a biodegradability of more than 90%, and has little environmental pollution. The purpose of adding it in the present invention is to dissolve carbon molecules in the physical and chemical process, to achieve full combustion, and to play a role in fuel purification.

[0059] Vinyl acetate: soluble in alcohol, acetone, benzene, chloroform. In the present invention, it is used as an intermediate and adhesive for smoke suppressants, pour point depressants, and thickeners.

[0060] Isopropyl alcohol: As a solvent, it is a relatively cheap solvent in industry. It can mix freely with water and has a stronger solubility for lipophilic substances than ethanol. It is an extractant and can be used as an antifreeze, a cleaning agent, an additive for blending gasoline and diesel, an antifreeze, a dehydrating agent, etc.

[0061] Energy-saving and efficiency-enhancing combustion aid: This is a patented technology (CN105062589A) that the inventor has successfully applied for an invention patent for. The product is added to clean and environmentally friendly biofuel to improve its calorific value, burn fully, clean up coking and carbon deposits, and achieve energy-saving and efficiency-enhancing combustion-supporting effects. The fuel cleanliness is reduced to more than 99%, which is basically a zero emission effect.

[0062] The clean and environmentally friendly biofuel-diesel alternative fuel described in the present invention has a shelf life of more than 3 years. For details, please see the following oil quality shelf life comparison table:
