Problems solved by technology

However, emulsified oil cannot be used as fuel for internal combustion engines at present. The main reason is that emulsified oil cannot meet the requirements of internal combustion engines in terms of stability and oiliness.
Emulsified oil is a thermodynamically unstable emulsion system, and a high-power emulsifying device is required for emulsification. The appearance of emulsified oil is turbid, and the stability period is short. It is difficult to popularize and use it on vehicles with high fluidity, and it is necessary to prepare stable and cheap W / O Type micro-emulsion fuel oil, the first consideration is the efficiency of the surfactant, most of the current use of a single surfactant, and generally require a higher concentration of surfactant

Abstract

The invention relates to a fuel oil emulsifier and a preparation method thereof, and belongs to the technical field of fuel additives. In the provided fuel oil emulsifier, sodium aliphatic alcohol sulfate, sodium hydroxyethyl sulfonate, and polysodium amino acid are taken as the anionic surfactants; lauryl trimethyl ammonium bromide and octadecyl trimethyl ammonium bromide are taken as the cationic surfactants; n-butanol and isopropanol are taken as the co-surfactants, and isopropyl ketone is taken as the cosolvent. Compared with the conventional anion / non-ion compounded surfactants and cation / non-ion compounded surfactants, the provided fuel oil emulsifier is more efficient, the micro-emulsification effect is better, the system is more stable, the micro-emulsified fuel oil processed by the fuel oil emulsifier can be store for a longer time, the fuel oil will not layer after being stored for six months or more, the phenomenon of oil-water separation will not happen, no precipitation is generated, and the processed fuel oil is convenient for storage and transportation.

Description

technical field [0001] The invention relates to a fuel oil emulsifier and a preparation method, belonging to the technical field of fuel additives. Background technique [0002] Researchers began to study fuel water mixing technology in the 1930s. The emulsified oil prepared by mixing fuel oil with water has been widely used in industrial combustion furnaces. The emulsification technology of fuel oil has been applied in some developed countries. However, emulsified oil cannot be used as fuel for internal combustion engines at present, mainly because emulsified oil cannot meet the requirements of internal combustion engines in terms of stability and oiliness. Emulsified oil is a thermodynamically unstable emulsion system, and a high-power emulsifying device is required for emulsification. The appearance of emulsified oil is turbid, and the stability period is short. It is difficult to popularize and use it on vehicles with high fluidity, and it is necessary to prepare stable ...
