6 results about "Cetane Improver" patented technology

This invention belongs to the field of diesel additive technology, and particularly relates to a diesel cetane number improver and its preparation process, comprising the following steps: mixing isooctyl nitrate, n-hexadecane, n-eicosane, oleic acid, and 2,6-di-tert-butyl-p-cresol to obtain a premix; mixing anhydrous ethanol, glycerol, and an emulsifier, adding the premix, reacting, and drying to obtain microparticles; mixing ethyl acetate, isopropanol, n-butanol, and an emulsifier, adding hexadecyl alcohol and EVA-210 to dissolve, to obtain a film-forming solution; mixing ethyl acetate and isopropanol, adding the microparticles and the film-forming solution, removing ethyl acetate, isopropanol, and n-butanol, adding the solution to liquid paraffin and mixing to obtain the diesel cetane number improver. The diesel cetane number improver prepared by this invention can prevent isooctyl nitrate from directly contacting the external environment, slow down the generation rate of free radicals, effectively improve and stabilize the cetane number of diesel, and maintain the cetane number of diesel at a high level for a longer period of time.

The invention relates to the technical field of diesel additives, and particularly discloses a multi-effect composite diesel additive and a preparation method thereof. The additive comprises the following components in parts by weight: 7-11 parts of an anti-wear agent, 5-8 parts of a cetane number improver, 4-6 parts of a clearing agent, 2-3 parts of an antioxidant, 3-4 parts of a solubilizer, 3-4 parts of a pour point depressant, 1-2 parts of a preservative and 4-7 parts of a multifunctional additive. The invention also provides a preparation method of the composition. All the components act together to achieve the multiple effects of improving the combustion quality, reducing emission, strengthening lubrication and the like, in addition, the prepared auxiliary agent integrates multiple functions, and the oil phase adaptability and the functional strength can be guaranteed.

The application discloses an environment-friendly and energy-saving diesel engine clean fuel, and particularly relates to the technical field of clean fuel.The environment-friendly and energy-saving diesel engine clean fuel is prepared from an additive and kerosene in a mass ratio of 1:(300-430).The additive comprises the following raw materials in parts by mass: a cetane improver 40-62 parts, an anti-knock agent 5-10 parts, an anti-corrosion agent 15-30 parts, dimethyl silicone oil 8-10 parts, and a cleaning agent 3-6 parts.The additive is mixed with kerosene, the stability of the fuel is further improved, the utilization rate of the fuel is improved, so that the prepared clean fuel can be effectively combusted in use, and environmental pollutants generated in the combustion process are reduced.

The invention belongs to the technical field of diesel additives, and particularly relates to a diesel cetane number improver and a preparation process thereof, and the preparation process comprises the following steps: uniformly mixing isooctyl nitrate, n-hexadecane, n-eicosane, oleic acid and 2, 6-di-tert-butyl p-cresol to obtain a premixed solution; uniformly mixing absolute ethyl alcohol, glycerol and an emulsifier, adding the premixed solution, reacting, and drying to obtain particles; uniformly mixing ethyl acetate, isopropanol, n-butyl alcohol and an emulsifier, adding hexadecanol and EVA (Ethylene Vinyl Acetate)-210, and dissolving to obtain a film forming solution; and uniformly mixing ethyl acetate and isopropanol, adding the particles and the film-forming liquid, removing ethyl acetate, isopropanol and n-butyl alcohol, adding into liquid paraffin, and uniformly mixing to obtain the diesel cetane number improver. The prepared diesel oil cetane number improver can prevent isooctyl nitrate from being in direct contact with the external environment, slow down the generation speed of free radicals, effectively improve and stabilize the cetane number of diesel oil, and enable the cetane number of the diesel oil to be maintained at a high level in a long time.
