Abstract

The invention discloses a heavy-oil emulsifier capable of creating a micro-emulsion state, belonging to the field of energy chemistry. The heavy-oil emulsifier disclosed by the invention comprises the following components: mahogany petroleum sulfonate, polyoxyethylene ether sulfonate, sorbitan sesquioleate, glycol aliphatic ester, alkylphenol polyoxyethylene, polyethylene glycol (400) bistearate, phosphate starch, sodium carbonate, water, polymethacrylate and succinimide. After being mixed with water, the emulsifier disclosed by the invention can be distributed into heavy oil to form micro-emulsion; the micro-emulsion has better thermodynamic stability and can be completely miscible with heavy oil; after being miscible, the heavy oil and water layering phenomenon cannot be generated after storing for a long time (more than two years); furthermore, by applying the heavy-oil emulsifier disclosed by the invention, the vaporization rate of heavy oil fuel can be stably increased, so that fuel in the micro-emulsion state is more uniform and is more sufficient to burn, and therefore, the purposes of saving energy and protecting the environment are really achieved.

Description

technical field [0001] The invention belongs to the field of energy chemistry. The invention relates to an emulsifier, in particular to a heavy oil emulsifier which can create a micro-emulsion state and is applied in heavy oil fuel. Background technique [0002] The vast majority of crude oil in my country is heavy crude oil, and the yield of heavy oil is generally about 50% of petroleum. The main role of heavy oil is to make fuel in many places such as oil refineries, chemical plants and steel plants. Due to the high content of asphaltenes and colloids in heavy oil, the vaporization is incomplete, which leads to incomplete combustion, resulting in a large amount of waste in combustion, and also pollutes the environment. Heavy oil mixed with water emulsification is an energy-saving technology. Generally, the fuel-saving rate reaches 10%-20%. It not only saves energy, but also reduces environmental pollution and reduces the content of CO and smoke in the flue gas. In recent...
