Problems solved by technology

But the common defect that these existing emulsifiers have is: 1. complex compatibility, too many ingredients
This will inevitably bring a lot of inconvenience and trouble to the preparation and deployment.
②The emulsified diesel oil produced by these emulsifiers has uneven particle size, so it is difficult to pass through the filter element of the fuel filter, and precipitates and accumulates in the filter, which affects the normal operation of the engine
③The strength of the interface film is low, easy to demulsify and decompose, oil and water are separated, and the emulsification performance is unstable
Therefore, it is better to use pure diesel oil to save time and worry, so so far, there is no diesel emulsifier and emulsified diesel oil prepared by it that customers are willing to use.

Embodiment Construction

[0024] Diesel oil emulsifier of the present invention comprises anionic surfactant dodecylbenzene sulfonate, nonionic surfactant sorbitan ester and water-soluble metal salt three components that can improve calorific value, they The weight percentage is as follows:

[0025] Dodecylbenzenesulfonate 10-16%

[0026] Sorbitan Ester 70-85%

[0027] Water-soluble metal salt 5-14%

[0028] Wherein dodecylbenzenesulfonate is its sodium salt (sodium dodecylbenzenesulfonate), calcium salt (calcium dodecylbenzenesulfonate), magnesium salt (magnesium dodecylbenzenesulfonate) or Ammonium salt (triethanolamine dodecylbenzenesulfonate).

[0029] Sorbitan ester is a series of products with the trade name SPAN (such as span20 is sorbitan laurate, span-40, span-60 is sorbitan monostearate, span- 65. span-80 (sorbitan monooleate, span-83 (sorbitan sesquioleate, span-85) or sorbitan dioleate.

[0030] Water-soluble metal salts can be sulphates of iron, aluminum, cobalt, potassium, nickel, an...

Abstract

The diesel oil emulsifier contains dodecyl bensosulfonate 10-16 wt%, dewatered sorbate 70-85 wt% and water soluble metal salt 5-14 wt%. The emulsified diesel oil contains water over 20 wt% and the emulsifier 0.8-1.5 wt% other than diesel oil. The present invention solves the technological problem of making emulsified diesel oil with water content over 20 % possess heat value of 85 % that of pure diesel oil.

Description

Technical field: [0001] The present invention relates to the emulsification treatment of fuel oil mixed with water, in particular to the diesel oil emulsifier and the emulsified diesel oil which can increase the water content and still maintain the combustion heat. Background technique: [0002] Combustion mixed with water, especially diesel oil mixed with water, can not only improve combustion conditions and save fuel, but also significantly reduce exhaust smoke and odor, which has a significant effect on improving urban air pollution. The key to watering diesel oil lies in two aspects of emulsifier and stirring technology. Usually a certain emulsifier has its specific requirements for mixing technology. For emulsifiers, there have been a large number of published documents at home and abroad to report in detail, and various emulsifier compatibility schemes have been proposed, all of which have positive effects. But the common defect that these existing emulsifiers have i...
