Description

Technical Field

[0001] The invention relates to a composite fuel, in particular to a formulation and preparation method of a polymer composite fuel composed of water, alcohols, diesel, additives, cetane improvers, etc. Background Art

[0003] Boilers and industrial furnaces are simply and inefficiently polluting. The rapid growth of the motor vehicle population has led to increasingly serious atmospheric environmental pollution. The simple and inefficient pollution of boilers and industrial furnaces and motor vehicle exhaust emissions are one of the main sources of PM2.5. Reducing carbon, reducing pollution, and expanding greenery are the core of improving air quality. Therefore, whether for energy security considerations or for energy conservation and emission reduction purposes, developing alternative energy, clean energy, and renewable energy has become an urgent task. Summary of the Invention

[0004] The purpose of the present invention is to provide a polymer composite fuel composed of water, alcohols, diesel, additives, cetane improvers, etc., which does not stratify during storage and use, can minimize environmental pollution, has no adverse effects on the equipment used, has good combustion effect, can reduce production costs, and is a polymer composite fuel synthesized under normal temperature and pressure conditions.

[0005] The content of the present invention is: A polymer composite fuel composed of water, alcohols, diesel, additives, cetane improvers, etc., characterized in that the composition (by weight%) is:

[0006] The water described in the present invention is softened water after filtration.

[0007] The alcohols described in the present invention are methanol, ethanol, butanol, etc. with a content of ≥50%.

[0008] The diesel described in the present invention is No. 0 diesel.

[0009] The additive described in the present invention is composed of the following components (by weight%):

[0010] The cetane improver described in the present invention is composed of the following components (by weight%): Alkyl nitrate 0.1 - 8.0% Isopropyl nitrate 0.1 - 5.0%

[0011] A method for manufacturing a polymer composite fuel composed of water, alcohols, diesel, additives, cetane improvers, etc., is prepared by the following steps in terms of weight percentage:

[0012] Under normal temperature and pressure conditions, place water, alcohols, diesel, additives, and cetane improvers in their respective containers, take and mix them evenly according to the proportions of the respective components, and then store them sealed; One: For the additives, also under normal temperature and pressure conditions, mix naphthenic acid, oleic acid, alcohols, hydroxylamine, ethanolamine, and hydrazine hydrate evenly according to the proportions of the respective components, and then filter; Two: For the cetane improver, under normal temperature and pressure conditions, mix alkyl nitrate and isopropyl nitrate evenly according to the proportions of the respective components, and then filter.

[0013] The high molecular composite fuel such as water, alcohols, diesel, additives, and cetane improver described in the present invention exists in a water-in-oil state. The water droplets gasify prior to diesel in the high-temperature combustion chamber, causing the oil film surrounding the water droplets to explode into countless small pieces, and the surface tension of each fragment itself will form new oil droplets. Due to the "micro-explosion" phenomenon, each oil droplet undergoes "secondary atomization", making its combustion more complete and achieving the purpose of fuel saving. At the same time, after the water gasifies, the water vapor at high temperature reacts with the unburned free carbon in the fuel to form a "water-gas reaction", releasing carbon monoxide and hydrogen, and participating in the combustion, which is also one of the energy-saving mechanisms in terms of chemistry. Alcohols are one of the main combustion agents of this fuel and play a role in reducing the freezing point to solve the fluidity of the high molecular composite fuel at a winter temperature of 0 degrees Celsius. The additives are mainly composed of lipophilic agents (naphthenic acid, oleic acid), hydrophilic agents (hydroxylamine, ethanolamine, hydrazine hydrate), etc. After adding the cetane improver to the components, the combustion characteristics of the high molecular composite fuel are improved, the ignition performance can be changed, the ignition time can be shortened, the ignition point can be reduced, the thermal working condition power performance of the locomotive can be improved, the power performance can be increased, the exhaust emissions of diesel vehicles can be reduced, and the fuel-saving effect is very obvious.

[0014] Compared with the prior art, the present invention has the following characteristics:

[0015] 1. The color of the high molecular composite fuel of the present invention is similar to that of pure diesel.

[0016] 2. The high molecular composite fuel of the present invention has a long stability period and does not delaminate for more than half a year.

[0018] 4. The raw materials of the high molecular composite fuel of the present invention are rich, easy to obtain, and the production cost is low.

[0019] 5. The amount of water incorporated in the high molecular composite fuel of the present invention is large, it does not delaminate during storage and use, has good stability, and has a good combustion effect.

[0020] 6. The high molecular composite fuel of the present invention can achieve good use and fuel-saving effects. It can be widely applied to internal combustion engines, industrial furnaces, and can also be used as fuel in boilers.

[0021] 7. The polymer composite fuel of the present invention can reduce environmental pollution. The equipment emissions are less polluting, and the harmful emissions are significantly lower than those of using 0# diesel. The reduction rate of carbon monoxide (CO) is 71 - 86%, with an average reduction of 79.4%; the reduction rate of carbon dioxide (CO2) is 6.1 - 9.8%, with an average reduction of 8.1%; the reduction rate of nitrogen oxides (NOx) is 13.2 - 58.6%, with an average reduction of 31.3%; the reduction rate of tail gas smoke density at a stable speed is 78.8 - 91%, with an average reduction of 85.9%; the smoke density during free acceleration drops by 51.8%, and the sulfur content is 0.001152%, making it a low-carbon and environmentally friendly product.
