Abstract

The invention relates to a multifunctional fuel oil addition agent and a preparation method of the multifunctional fuel oil addition agent. The preparation method comprises the steps of weighing and taking raw materials which comprise, by component and weight, 90-95 parts of normal paraffin, 3-6 parts of isomerism paraffin, 1-2 parts of olefin, 1-2 parts of cyclo-paraffin and 0.2-0.8 part of aromatic hydrocarbon, stirring and mixing the raw materials for 2-3 hours, obtaining a crude product, then, adding oily solvent, enabling the volume ratio of the oily solvent to the crude product to be 1 to 30, mixing the compound for 2-3 hours, and obtaining a yellow liquid product. Compared with the prior art, the multifunctional fuel oil addition agent has the advantages of being small in sulfur content, good in dispersing property and the like.

Description

technical field [0001] The invention relates to an additive, in particular to a multifunctional fuel oil additive and a preparation method thereof. Background technique [0002] Almost all sulfur in fuel oil is oxidized to SO during combustion 2 , about 3% (volume fraction) of SO 2 converted to SO 3 . When the flue gas temperature is higher than 400 °C, SO 3 The gas does not corrode metals, but SO 3 The presence of the flue gas dew point rises. When the flue gas temperature drops below 400°C, SO 3 The gas combines with water vapor to form sulfuric acid vapour. [0003] Existing fuel oil additives are oil-soluble organic magnesium additives formed by combining alkanes or aromatic hydrocarbons, organic acids, and metal compounds at a certain temperature and time. The main component is oil-soluble magnesium compounds. Combustion accelerant and dirt loosening agent, etc. The main mechanism for reducing the dew point temperature of flue gas is: the magnesium compound in ...
