Abstract

The invention provides a nanometer fuel additive and a preparation method thereof. The nano-fuel additive of the present invention includes a non-polar solvent and the following components: nano-silver and / or nano-silver alloy; water dispersant; emulsifier; detergent, the reaction solvent is added to the reaction kettle, and the water bath is heated to reflux; Add the dispersant to the reaction kettle and stir to dissolve; add the silver and / or silver alloy salt to the reaction kettle after dissolving in water; add the dispersant and reducing agent to the water in turn, slowly drop into the reaction kettle after dissolving, and continue to stir after the dropwise addition Cool, discard the supernatant, add emulsifier, detergent and solvent in turn, stir evenly, and filter with ultrafiltration membrane to obtain nano fuel additive. The nano-fuel additive in the invention can effectively improve power, save fuel, reduce emissions, reduce friction and reduce noise, and can play an important role in the fields of automobiles, ships, trains, oil-fired boilers and oil-fired generators.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a nanometer fuel additive and a preparation method thereof. Background technique [0002] The current rapid development of industrial technology has led to a sharp increase in the demand for energy, especially petroleum energy. Petroleum energy is a limited energy source that cannot be recovered after consumption. Therefore, before an alternative energy source is found, it is particularly important for the survival and development of human beings to increase the utilization rate of petroleum energy and save the limited petroleum energy. Therefore, energy conservation has become a worldwide issue, and the energy crisis has become a difficult problem that governments all over the world must face. [0003] This problem is particularly serious in our country. Compared with foreign countries, the quality of fuel oil in our country is relatively much worse. Taking gaso...
