Problems solved by technology

[0002] Diesel oil emulsification technology has spanned two centuries, from milky white emulsified diesel oil to transparent micro-emulsion diesel oil, but it has not been industrialized and put into the market as commodity oil. The main reason is that the existing diesel emulsification technology one-sidedly pursues the maximization of water content and profit, while ignoring the repair and conditioning of various physical and chemical indicators in the oil phase, so various difficult problems appear in actual use
Common problems include: (1) Poor fluidity and high viscosity, resulting in poor atomization of fuel injection, frequent carbon deposits in fuel injectors, and difficulty in cold starting at low temperatures
⑵ Low calorific value and cetane number, resulting in insufficient power, insufficient combustion, high fuel consumption, and actually fail to achieve the purpose of energy saving
⑶ Due to the unreasonable additive formula, long-term use will easily cause corrosion to the cylinder block and ferrous metal parts of the power machine, thus shortening the normal service life of the power machine
⑷ Poor stability, easy to oxidize, darken the color, increase sediment and colloid, form a large amount of carbon deposits in the combustion chamber, increase cylinder wear and tear, and it is difficult to promote as commercial oil
⑸ Saponification and demulsification in water, poor miscibility, turbidity and stratification after miscibility with various grades of diesel oil, resulting in power machine failure

Abstract

The invention discloses practical micro-emulsified environment-friendly and energy-saving diesel oil and a preparation method thereof. The yellowish and crystal practical micro-emulsified environment-friendly and energy-saving diesel oil is prepared by stirring 60-80% of diesel oil, 5-20% of aviation kerosene, 6-12% of micro-emulsifying agent, 6-13% of water and 0.5-2% of modifier for 10-20 minutes under normal temperature and normal pressure. The practical micro-emulsified environment-friendly and energy-saving diesel oil has the advantages of good fluidity, high impetus, low oil consumption, practicability, environment friendliness, energy saving, simplicity in production equipment, wide source of raw materials, low investment and high economic benefit, and can be widely popularized and utilized as commercial oil.

Description

technical field [0001] The invention belongs to the field of microemulsion diesel oil, and in particular relates to a practical microemulsion environment-friendly and energy-saving diesel oil and a preparation method thereof. Background technique [0002] Diesel emulsification technology has spanned two centuries. From the development of milky white emulsified diesel oil to the current transparent micro-emulsion diesel oil, it has not been industrialized and put into the market as commercial oil. The main reason is that the existing diesel emulsification technology only pursues water content and profit. The maximization of oil phase, while ignoring the repair and tempering of various physical and chemical indicators in the oil phase, so there are various difficult problems in actual use. Common problems include: (1) Poor fluidity and high viscosity, resulting in poor atomization of fuel injection, frequent carbon deposits in fuel injectors, and difficulty in cold starting at...
