Abstract

The invention relates to the field of ship fuel oil, and particularly discloses ship fuel oil which is prepared from the following raw materials in parts by weight: 70-80 parts of residual oil, 55-65 parts of shale oil, 60-70 parts of phenolic oil, 0.02-0.08 part of an emulsifier and 0.02-0.06 part of a stabilizer; wherein the emulsifier is prepared from the following raw materials in parts by weight: 2-5 parts of diisobutyl sulfosuccinate sodium salt, 3-7 parts of sodium lignin sulfonate, 5-9 parts of triethanolamine, 2-5 parts of nonylphenol polyoxyethylene ether, 0.1-0.3 part of a polyether modified organic silicon defoaming agent and 20-24 parts of water. The fuel oil has the advantage that the fuel oil is not easy to layer after being placed for a long time.

Description

technical field [0001] The application relates to the field of marine fuel oil, more specifically, it relates to a marine fuel oil and a preparation method thereof. Background technique [0002] Ship fuel oil is used for marine navigation. If there is too much water in the ship fuel oil, stratification will occur, and it will cause engine failure during use, and it will also cause corrosion of fuel system components. Therefore, ship fuel oil is usually It is necessary to add a dewatering agent to use the emulsification effect of the dehydrating agent to emulsify the water in the fuel oil, so that the water can be evenly distributed in the fuel oil of the ship, and eliminate the adverse effects of accumulated water on the engine. [0003] In the related art, the dewatering emulsifier includes components such as n-decyl alcohol, n-octanol, petroleum ether, n-butanol, naphthenic acid, oleic acid, sodium dodecylbenzenesulfonate, ethylenediamine, triethanolamine, etc. Mix it acc...
