Abstract

The invention relates to a preparation method of high-combustion-efficiency C10 fuel oil. The method includes the following steps: (1) first, mixing additives and oil solvent with the volume ratio of 1:30 in a reaction tank and emulsifying the mixture into liquid, and during the mixing process, adding the additives into the oil solvent and stirring the oil solvent and then obtaining uniform yellow liquid through the mixing; (2) adding the mixed yellow liquid into C10 fuel oil along a heavy oil pipeline with the weight ratio of 2-8%; and (3) after the C10 fuel oil contacts with the yellow liquid, carrying static mixing through the pipeline. Compared with the prior art, the method has the advantages that the product is high in fogging degree and combustion efficiency and the like.

Description

Technical field [0001] The invention relates to the field of C10 fuel oil, in particular to a method for preparing C10 fuel oil with high combustion efficiency. Background technique [0002] C10 fuel oil is a by-product separated from gasoline hydrogenation in ethylene production equipment. At present, C10 fraction is a yellow-brown transparent liquid, which is widely used in industries such as resin making and industrial furnace fuel. Generally speaking, it is used in the combustion of liquid fuels. Among them, fuel and oxidant (usually air) are in different phases, so they are in heterogeneous combustion. When liquid fuel burns, its chemical reaction speed is much greater than its diffusion and mixing speed, so it is a heterogeneous diffusion combustion. The vaporization temperature of liquid fuel is much lower than its ignition temperature, and the liquid fuel actually vaporizes before it catches fire. Therefore, the combustion of liquid fuel is essentially a combustion reac...
