Problems solved by technology

In the patent document CN200410013731.6, the emulsifier and the emulsification method used for emulsifying fuel oil are described in detail, but because it only uses an emulsifier without a co-emulsifier, it is difficult to emulsify the fuel oil, and it must be used. Advanced emulsification equipment and emulsification process

example 1

[0015] Take 5 parts of heavy residue oil by-product of petroleum, its viscosity at 100℃ is 500mm 2 / s; 93.9 parts of shale oil with a viscosity of 5mm at 50°C 2 / s; The amount of emulsifier Sparene-80 is 1 part, the coupling agent ethanol is 0.1 part, and the metal deactivator T1201 is 1×10 -6 The fuel oil is obtained by adding it to the blending tank at 55-65°C and fully stirring for 10-14 hours to filter out impurities. The finished fuel oil obtained meets the 4# fuel oil index.

example 2

[0017] Take 30 parts of heavy residue oil by-product of petroleum, its viscosity at 100℃ is 800mm 2 / s; 66.5 parts of shale oil with a viscosity of 11mm at 50°C 2 / s; The emulsifier uses alkylphenol polyoxyethylene ether NP-4, the dosage is 3 parts, the coupling agent uses glycerol 0.5 parts, and the metal deactivator T1201 is 2×10 -6 The fuel oil is obtained by adding it to the blending tank at 55-65°C and fully stirring for 10-14 hours to filter out impurities. The finished fuel oil obtained meets the 120# fuel oil index.

example 3

[0019] Take 50 parts of heavy residue oil by-product, and its viscosity at 100°C is 1200mm 2 / s; 46 parts of low temperature coal tar, its viscosity at 50°C is 18mm 2 / s; the amount of emulsifier Benzene-80 is 1 part, the amount of emulsifier alkylphenol polyoxyethylene ether NP-4 is 1 part; the coupling agent butanol is 2 parts, the metal deactivator T1201 is 5×10 -6 The fuel oil is obtained by adding it to the blending tank at 55-65°C and fully stirring for 10-14 hours to filter out impurities. The finished fuel oil obtained meets the 180# fuel oil index.

Abstract

The invention relates to an energy-saving fuel oil composition. The composition consists of the following materials in part by weight: 5 to 70 parts of petroleum byproduct heavy residual oil, 24 to 93.9 parts of light fuel oil, 1 to 5 parts of emulsifying agent, 0.1 to 2 parts of coupling agent and 1*10<-6> to 5*10<-6> part of metal passivator, wherein the light fuel oil is shale oil or low-temperature coal tar; the emulsifying agent is one or a combination of two of Span-80 and alkylphenol polyoxyethylene ether NP-4; the coupling agent is ethanol, glycerol or butanol; and the metal passivator is N,N'-bis(salicylidene) propanediamine. The energy-saving fuel oil composition has the advantages of thermodynamic stability, difficult separation of heavy fuel oil component, high storage stability, high fuel oil combustion heat value efficiency, obvious reduction in harmful gas emission and no corrosion on a combustion machine and an oil line.

Description

Technical field [0001] The invention belongs to an energy-saving fuel oil composition, which is suitable for fuel oil used in industries such as ship engines, industrial power generation machinery and civil boilers. Background technique [0002] The fuel oil commonly used in marine engines, industrial power generation machinery, and civil boilers is blended with heavy residue components mixed with lighter oils with lower viscosity. Petroleum by-product heavy residue is the residue of crude oil after atmospheric distillation or vacuum distillation. It is generally composed of four components: asphaltenes, gums, aromatic hydrocarbons, and alkanes. The asphaltenes and gums form gums. The clusters are dispersed by the two dispersants of aromatic hydrocarbons and alkanes, the distance between the micelles is large, the mutual attraction is small, and a highly dispersed sol-type structure is formed. The light component oil added to the blended fuel oil generally includes light diesel ...
