Problems solved by technology

[0005] 1. Insufficient stability of long-term storage: Most emulsified fuel oils can only maintain oil-water separation for a few days at most when stored at room temperature, so they generally need to be used immediately after production, so it is not conducive to long-distance transportation or mass production;
[0006] 2. In use, it is found that these emulsified fuel oils are not easy to ignite, and the calorific value of combustion will decrease with the amount of water added (for example, when the amount of water added is 20% by weight, the calorific value is reduced to 70% of the fuel oil of the same volume), moreover, When the amount of water added is 30% by weight, it cannot be ignited, thus limiting its industrial applicability

Abstract

The invention provides an emulsified synthetic fuel and method of manufacture, wherein the emulsified synthetic fuel is in water-in-oil shape, its composition is, 550-800 parts by weight of fuel oil, 200-450 parts by weight of water, and 2-20 parts by weight of addition agent, the addition agent comprises non-ionic surface active agent with a HLB value of 2.5-8, a stabilizer and an anti-oxidizing agent. The invention also discloses the process for preparing the emulsified synthetic fuel.

Description

technical field [0001] The invention relates to an emulsified synthetic fuel oil, in particular to a water-in-oil (W / O) emulsified synthetic fuel oil. The present invention also relates to a method for producing the water-in-oil (W / O) type emulsified synthetic fuel oil. Background technique [0002] The heat energy generated by burning fuel oil (such as heavy oil) can be further converted into mechanical energy or electrical energy, which is commonly used in boilers or engines. Due to the increasing awareness of environmental protection in the world, countries strictly control the waste gas generated by the combustion of petrochemical raw materials. Therefore, how to reduce the emissions of sulfur oxides (SOx), nitrogen oxides (NOx) and carbon oxides (COx) from fuel oil combustion The concentration and total amount of pollutants is a major issue in current environmental protection. [0003] In order to solve the above problems, a method of mixing fuel oil, water and approp...
