Problems solved by technology
However, there are still some problems in emulsified oil oil-water separation, low combustion efficiency, emulsified oil storage stability and emulsification process technology.
At present, there are no reports of multifunctional heavy oil and fuel oil additives that can not only emulsify heavy oil with water, but also catalyze and support combustion, and can also highly disperse residues in emulsified oil, thereby greatly improving the storage stability of emulsified oil.

Embodiment Construction
[0034] Example number
[0035] The advantages of the formula in this embodiment are strong applicability, and can be widely applied to various heavy oils. The formula of Example 2 increases the active ingredient of the catalyst, and the catalytic and combustion-supporting effect is stronger. Example 3 formula adopts isooctanoate, the additive product has good storage stability, and the product color and appearance are bright and good. The formula of Example 4 strengthens the effect of the detergent and dispersant, the storage stability of the emulsified oil is stronger, and the combustion is clean.

Abstract
An oil-soluble multifunctional additive for heavy oil or fuel oil contains more surfactants, composite catalytic combustion adjuvant and detergent disperser, and is characterized by saving oil by 10-25%, increasing added water to 10-30% and eliminating black smoke. A process for preparing emulsified heavy oil or fuel oil is also disclosed.
Description
technical field [0001] The invention belongs to a multifunctional heavy oil and fuel oil additive in chemical industry and energy, and its preparation and application technology in emulsified oil of heavy oil and fuel oil. Background technique [0002] In order to save energy and improve the combustion status of heavy oil, scientists at home and abroad have done a lot of work on the emulsification of heavy oil with water and the preparation of emulsified heavy oil. At present, emulsified heavy oil prepared with various additives and different emulsification processes has also been applied to varying degrees in various countries. However, there are still some problems in emulsified oil oil-water separation, low combustion efficiency, emulsified oil storage stability and emulsification process technology. At present, there are no reports of multifunctional heavy oil and fuel oil additives that can not only emulsify heavy oil with water, but also catalyze and support combustio...
