Description

[Detailed description of the invention] Liquid fuel additive East Suyu Muru Ran 1 The present invention applies to liquid fuels including fuel oil, gas oil and motor diesel. Regarding additives for gel oil.

Conventional technology Improves flammability, reduces corrosion damage and A suitable additive added to a liquid fuel for the purpose of reducing the accumulation of impurities in the system. The drug has been under development for many years.

In addition, many liquid fuel additives have been commercially available and in use, but unfortunately There is nothing to be satisfied with. Soot and oil coke are reduced when using different metals. The effect of

A slight excess of air is used to reduce the formation of sulfuric acid and therefore corrosion. It is advantageous if Burning oil in the presence of a slight excess of air is less efficient. improved. However, the excessive amount of air creates a large amount of soot and oil coke. There are also disadvantages created in quantity.

Disclosure of invention The purpose of the present invention is to provide additives that are superior to previously known additives and provide economic benefits to the user. It not only improves fuel efficiency, but also improves combustibility, i.e. efficiency. Reduces the amount of impurities that accumulate or deposit in the combustion system and reduces the amount of environmental emissions. We propose a new additive that reduces corrosion damage caused by acid components such as sulfuric acid. It is about providing.

The above purpose is 1) Fatty acid manganese salt and 2) High boiling point tar oil and 3) Naphthalene and Contains the following additional ingredients if desired: 4) Iron naphthenate.

5) Ferric chloride and 6) Calcium salts of fatty acids.

This is achieved by the liquid fuel additive of the present invention, which is characterized by containing one or more of the following: .

Examples of manganese salts that can be used include nomankane salts of branched chain fatty acids having 8 to 9 carbon atoms. t+anganese Siccator commercially available from Akzo Chemie [Mn about 10%, non-volatile substances 61-67%, mineral spirit (white Spirit) 35% content] and NLIOdeX” mouth ryer Han (lane ``se'' is exemplified.

“NuOdeX Dryer Iron” is an example of a suitable iron naphthenate. shown.

Suitable high-boiling tar oils include oils containing polyaromatic hydrocarbons, such as An example is tracene oil. When anthracene oil is heated, 40% of it becomes 330- Distill at a temperature of 400°C. The flash point of anthracene oil is 180℃ in a closed container. be. 1. As calcium salts of suitable fatty acids, calcium salts of branched chain fatty acids with 8-9 carbon atoms are used. Lucium salts, such as Calcium 5ic, commercially available from Akzo Chemie catol CCa approximately 5%, non-volatile components 47-52%, balance mineral salt or 'Nuodex Dryer Calcium'.

The additive of the present invention is manufactured from the three essential components described above.

That is, tar oil is heated until it becomes a liquid, and naphthalene is added during continuous heating to homogenize it. The manganese salt formulation is then mixed to form a quality liquid mixture.

The additive of the present invention containing the above six components is a calcium salt preparation.

A mixture obtained by stirring and mixing a manganese salt preparation and an iron naphthenate preparation; Blend (addition) of a molten mixture of separately prepared tar oil, ferric chloride and naphthalene Manufactured by

Before additives are commercialized as products, they must be mixed stably so that they can be more easily mixed with fuels. Kerosene is added to get things.

The mixing ratio of each component is within the normal range 1) Fatty acid manganese salt-containing preparation 1 0~1oop”2) High boiling point tar oil 1~3g 5) Ferric chloride 0-5 KH 2) Fatty acid calcium salt-containing preparation 0-80f! The content of active ingredients in the fuel When calculated, the mixing ratio I is assumed to be as follows. However, Todoroki calculated 4 1 minute iζ is certain, and the following values should be considered as an example.

1) Manganese salts of fatty acids (Mn conversion) 0.008-0.08Kff / Fuel 2) High boiling point tar oil 0.009-0.09 to 5/fuel 3) Naphthalene 0.04-0.12 89/ as fuel 4) Iron naphthenate preparation (Fe conversion) O-0.05K9 / Fuel 4) Ferric chloride 0-0.048 g/fuel 6) Calcium salts of fatty acids (Calculated as Ca)　O-0.03Kg/　The mixture of the above six components is normally used as fuel oil. Used for combustion.

Additives that do not contain component 6) are usually used for gas oil combustion.

Additives that do not contain component 6) are usually diesel oil (including motor diesel oil) used for combustion. However, adding calcium salts of fatty acids slowly may be preferable. This will remove the (hard) deposits that have accumulated on the machinery. positions) are unraveled.

The additives of the present invention reduce the surface tension of the fuel, resulting in finer atomization (a tomization) to achieve excellent work efficiency with fewer interruptions. It is thought that it acts on

The formation of soot with the combustion of liquid fuels is caused by atomized fuel droplets. ps) is too large. Therefore, it burns only incompletely, and only partially Passes through the boiler in an unburned state and is deposited in the form of soot in pipes and on other heated surfaces It is. Oil coke is also formed because the fuel droplets are too large. Ru. When the oil in a droplet is heated to a certain temperature, coke will form before the droplet burns out. This is because it becomes a social network. The formed oil coke particles under normal conditions It cannot be combusted and is therefore entrained with the exhaust gas. Using the additive of the invention The fuel can be atomized into finer particles by Much more complete combustion can be ensured than when combustion is carried out in the same state. finer liquid By atomizing the droplets, the temperature within the small droplets formed can more easily be raised to high temperatures. is maintained to ensure complete combustion. The center of the large droplet remains cool during combustion This can be avoided. Complete combustion introduces unburned impurities into the system This eliminates the possibility of contamination, thus preventing deposits and polluting emissions. enough fuel Once atomized, it can be operated with less air supply without interfering with complete combustion. I can do it. When the air supply decreases, the CO2 content in the exhaust gas increases. , resulting in optimal flammability and efficiency.

Together with the fuel oil additive of the present invention, 11 kerosene-containing additions per 1 ton of normal fuel oil agent is added. The addition of the latter additive improves the oil reserve that is normally done before combustion. Heating temperature can be lowered. Preheating is usually done using electricity and is less expensive. It gets heavy. The energy savings thus obtained may exceed the cost of the additive.

In some cases, the preheating temperature must not be lowered. Instead, it is completely burned and better results than during the error.

When the additive of the present invention is used in combustion systems for fuel oil, soot, oil coke, etc. The amount of carbon dioxide, clinker and sulfuric acid produced is reduced. Therefore, an insulating coat in the boiler High efficiency is achieved without the formation of ringing. In addition, the exhaust gas side suffered from corrosion. If water is present, it will be emulsified into the oil. As a result, the boiler It stays clean and dry, extending its lifespan. the system is more stable It works and requires fewer repairs.

When adding the additive of the present invention to gas oil, 11 kerosene-containing additives are added to 1 ton of oil. Additives are used. Additives prevent the formation of paraffin wax, tanks and tubes. Keep the pipes and filters clean and free from water or condensation present in the oil. Emulsifies the water formed and prevents corrosion. Temperatures up to -18℃ with additives protected at any time. finer atomization, thus ensuring more complete combustion and Accumulation of gas and coke is prevented.

Cleaner combustion reduces fuel consumption, making it suitable for diesel engines Wear and damage during use are suppressed.

The additive of the present invention can be used in stationary or mobile diesel engines such as marine engines. Suitable for addition to diesel oil used in engines. Usually, 1 ton of diesel oil 1 p of kerosene-containing additive is added. Due to additives, paraffin wax This reduces the amount of fuel produced, which helps keep the engine cleaner and starts faster. movement is promoted. Additives provide protection against temperatures down to -18°C . Tanks, tubes and filters are kept clean. With additives, de Both the water present in the diesel oil and the water formed by condensation is emulsified. Therefore, Nku.

Corrosion of tubes, pumps and valves is prevented. As a result of improved atomization, more Complete combustion is achieved and soot and coke deposits are avoided. low fuel consumption This reduces diesel engine wear.

Actual sales example The invention will be explained in more detail with reference to the following examples and tests.

Density: 0.85 Appearance: brown liquid Flash point: 55℃ Storage R durability: Infinite It is clear from the following tests that the additive of the present invention provides surprising effects. That's it.

Test 1 Fuel oil and additive containing 11 kerosene-containing additives produced in Example 1 per 1 ton of fuel oil compared with fuel oil that does not contain

The boiler was operated at 80% load and no adjustments were made to the boiler during the test. I didn't jump.

Two cases without additives (tests a and b) and two cases with additives (tests C and d) was tested. The results obtained are shown in Table 1.

Test 1 was repeated. However, Calcium 5iccatol 2Qj! and light Oil 50! Additives containing were used. The results obtained are shown in Table 2.

Table 2 As is clear from Tables 1 and 2, as a result of the reduction in the amount of solid substances released, soot The soot number is reduced, making the boiler system more economical. It can be activated. Conclusion of the test - To investigate the effect of Go addition Qi 1 on suppressing the release amount To! This is the result obtained without adjusting the <-ner.

The amount of emissions when using additives is determined by the Ministry of the Environment (Department of the Environment). Below the limit value (2,597 to 9 oil) prescribed by the Environmental Protection Agency - Higher economy during normal daily operation by readjusting the burner (higher Co2 percentage).

As mentioned above, the boiler was not adjusted during the test. The CO2- number obtained is almost It seems like nothing has changed. By adjusting the boiler appropriately, the CO2 content can be adjusted appropriately. It can be done.

Test 3 Three fuel oil systems were tested without additives. Co2 in exhaust gas The content was approximately 12.5% and the soot number (Bacharach) was approximately 5.

The same system was tested with 8% water added. The results were as follows . CO2 content 13.5%, soot number 3-4° Additive of Example 1 (light per ton of oil) The results obtained with the addition of oil-containing additive 11') are as follows. CO2-containing Rate 14.5%.

Soot number 2~3° No adjustments were made to the boiler during the above test.

It is known that CO2 content can be increased by emulsifying water in liquid fuel. It is. The additive of the present invention can further increase the CO2 content.

If water is not used, there will be less calcareous deposits and fewer repairs will be required.

With the additive of the present invention, the additive can be simply injected into the tank or by other easy methods. can be dispensed with water, eliminating the need for expensive emulsification systems traditionally used with water. is no longer necessary.

By using the additive of the present invention, cleaning that was previously frequently performed is now practical. becomes unnecessary. If the system has stopped for another reason and you want to perform a flush, You can do it from time to time.

In the above test, the boiler was cleaned after using the additive of the present invention but before starting the test. I turned it on.

Test 4 When a conventional gas-oil system is operated as usual, the CO2 content in the exhaust gas is Approximately 13%, soot number was 1-2.

The system was operated using the additive of Example 2 (111 per ton of gas oil). In this case, the Co2 content was about 14.5% and the soot number was O~1.

A chimney sweep who did not know that the additive had been used was cleaning it for the first time after using the additive. When the chimney is dry (completely dry, there is no solids that have accumulated at the bottom of the chimney to remove). I was surprised at how small the amount of the substance was.

There is less noise and odor during boiler operation compared to when no additives were used. It was also discovered that

Test 5 Older diesel-powered trucks have traditionally had starting problems and exhaust emissions are typically occured.

Add the additive of Example 3 at 1 ton per ton of diesel oil! ! If added, after 8 hours of operation There were no starting problems and no exhaust fumes. Trucks have better traction traction.
