CONSTITUTION:A strong acid having SO4<2-> in the form of a soln. obtd. by adding 3-5% conc. H2SO4 to an aq. soln. of pref. activated Ca3(PO4)2 is added to sea water and removing a precipitate thus formed, and the mixture is allowed to stand for 2-3hr, thereby lowering the pH value. A strong alkali (NaOH) is added thereto, and the mixture is allowed to stand for 10hr or more, thereby increasing the pH value. The precipitate thus formed is removed to prepare a soln. Then, water is removed from the soln. to prepare a solid. This solid is kneaded with an alcohol (e.g., ethanol) in an amt. ranging from 10% of the amt. of the solid to an amt. equal to the amt. of the alcohol, thereby preparing the title modifier. This modifier is housed in a liq.-permeable container and then put into a fuel housing tank in an exchangeable manner.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a modifier for improving the thermal efficiency of petroleum fuels such as gasoline and diesel oil, and particularly relates to a modifier for improving the thermal efficiency of petroleum-based fuels such as gasoline and diesel oil. This invention relates to a reforming agent for gasoline, etc., which uses an agent.

[Prior art and problems to be solved by the invention] In general, in spark ignition engines such as automobile engines, the higher the compression ratio of the engine, the higher the thermal efficiency, the greater the output, and the better the fuel efficiency. In this case, increasing the compression ratio will cause abnormal combustion and knocking, which will reduce thermal efficiency.

For this reason, gasoline with a high octane number and high anti-knock properties is used to increase the compression ratio and improve thermal efficiency. However, gasoline with a high octane number is generally made by blending various gasoline blending materials in appropriate proportions. It's expensive.

Furthermore, deterioration of gasoline due to oxidation causes a decrease in octane number and a significant deterioration in fuel consumption due to the polymer gum quality.

For this reason, it is necessary to add antioxidants to commercially available gasoline.

On the other hand, light oil used as fuel for diesel engines (compression ignition engines) has not only stability but also fluidity of 1.
Ignitability becomes a problem, and therefore a light oil with a high cetane number and good ignitability is required, but light oil with a high cetane number is also more expensive than ordinary light oil.

Furthermore, when light oil deteriorates due to oxidation, a high-molecular-weight gum is produced in the same manner as in the case of gasoline, and when this is produced in large quantities, it clogs the fuel injection nozzle and obstructs the supply of fuel. In order to prevent such problems due to deterioration of light oil, hydrorefining and the like are required.

An object of the present invention is to provide a reforming agent for gasoline, light oil, etc., which does not require special treatment or preparation of these fuels and can improve fuel efficiency and increase output.

A further object of the present invention is to provide a fuel modifier that can be exchangeably put into a fuel tank of an automobile or a fuel storage tank such as a stock tank, rather than being added directly to fuel.

[Means for Solving the Problems] The inventor of the present invention has already developed a combustion aid (Japanese Patent Application No. 31996/1983) made by dissolving a special alkaline agent in seawater, and has shown remarkable effects in improving combustibility. I got it.

He discovered that this combustion aid (liquid) had particularly excellent effects when added to the engine in the form of a spray, and developed a system for adding this combustion aid to the engine (Patent Application No. 61). -292170, Japanese Patent Application No. 61-319827).

However, since this combustion aid requires modification of the engine, etc., it could not be immediately applied to all automobiles.

Therefore, the present inventor discovered that certain elements contained in seawater,
Focusing on the synergistic effect of strong violence and improving flammability,
This is the result of extensive research into auxiliary agents that can be used without modifying the engine.

This led to the present invention.

That is, the reforming material for gasoline, etc. of the present invention can be obtained by making seawater acidic, then adding a strong alkaline agent to raise the pH, and removing the precipitate that is generated at that time, and further removing water from the resulting solution. The modifier is made of a mixture of solids and alcohol, and the modifier configured in this way can be stored in a container with pores and used by being exchangeably put into a tank that stores fuel. can.

Hereinafter, details of the modifier for gasoline, etc. of the present invention will be explained.

First, the solid modifier of the present invention is produced by separating components in seawater using a predetermined method. This predetermined method is disclosed in "Method for Separating Salt from Sea Water" (Japanese Patent Application No. 62-201578), which was already proposed by the present inventor. That is, first, seawater is adjusted to a low pH with a strong acid containing sulfate ions, then a strong alkaline agent is added to increase the pH, and the precipitate and solution that are generated at this time are separated.

Here, as the strong acid containing sulfate ions, several percent dilute sulfuric acid can be used, but an aqueous solution obtained by adding 3 to 5% concentrated sulfuric acid to an aqueous solution in which activated calcium phosphate is dissolved and removing the precipitate. (hereinafter abbreviated as P-8 acid) can be used. This P-S acid exhibits strong acidity with a pH of about 0.2, but unlike harmful substances such as sulfuric acid, it does not cause any abnormality when it comes in contact with the skin, and can be used as a highly safe acid that is easy to handle. By adding several percent of dilute sulfuric acid or P-8 acid to seawater and leaving it for 2 to 3 hours, seawater can be adjusted to a low pH of 2 or less. At this time, almost no precipitates are formed, but some precipitates are removed together with the original suspended matter in the seawater by means such as filtration.

Next, the strong alkaline agent is used to neutralize the seawater that has been adjusted to a low pH and raise the pH further.
Salts such as alkaline earth metals and other metal sulfates whose solubility decreases with H are precipitated. As such a strong alkaline agent, sodium hydroxide as it is, or a solution obtained by adding sodium hydroxide to an aqueous solution of calcium oxide (hereinafter abbreviated as Ca--Na aqueous solution) is used.

The amount of strong alkaline agent should be at least the amount that can achieve the above purpose, and usually sodium hydroxide (solid) is added at 3% to seawater, and Ca-Na aqueous solution is added at about 5% for 10 hours. Leave it alone.

As a result, the seawater becomes basic with a pH of 13 or more, and a precipitate is formed.

After removing this precipitate, solution (a) contains about the same amount of alkali metal ions as seawater, but contains less alkaline earth metal ions such as Ca and Mg, and mainly contains hydroxide ions and chloride ions as anions. It is a basic aqueous solution containing. This solution (a) is boiled down to a concentration of 10% to 1.5%, and when it is cooled after agricultural shrinkage, further precipitates are deposited, which are also removed.

The desired solid product is obtained by completely removing water from the remaining solution (b).

Solution (a) and solution (b) obtained by first separating seawater
Table 1 shows the results of elemental analysis of seawater.

This solution (b) is the solution obtained by first separating seawater (
Since it is obtained by removing a salt with a lower degree of dissociation as a precipitate from a), it is Na'' as a cation.

It mainly contains K+ and Ca''+, and contains more Li dione than seawater.

That is, this solid substance (c) obtained by removing water from the solution (b) mainly contains K.

Salts, oxides and hydroxides mainly containing Na and Ca,
It has very strong basicity.

Furthermore, it is known that a solution of Na metal in an alkaline earth oxide is an extremely basic substance called a super strong base and has an excellent desolvation effect, but the solid material according to the present invention It is thought that (c) also contains a large amount of such a super strong base or a compound similar to it, and the reforming of the fuel is also thought to be due to its unique properties.

Table 1 The modifier for gasoline, etc. of the present invention is a solid substance (c
) can be obtained by adding alcohol to make it sticky. The solid substance (c) is smooth and sandy in its original state, but by adding alcohol it becomes a viscous solid that is easy to handle and can be applied as a modifier, and it also improves its miscibility with fuels such as gasoline. gets better. As the alcohol, lower alcohols such as ethanol and methanol can be used, and the amount of alcohol in the solid substance (c) is about 10% to
Add the same amount, preferably about 40 to 60%.

The modifier for gasoline, etc. of the present invention produced in this way is
It can be widely used as a modifier for petroleum liquid fuels such as gasoline, light oil, and heavy oil, and by adding it to fuel, it can increase combustion efficiency, improve fuel efficiency, and increase output. Depending on how the fuel is used, this modifier may be added directly to gasoline, etc., but since it may clog the fuel supply system in engines etc., it should be stored in a container with pores. It is preferable to put the entire fuel into the fuel. One embodiment of the modifier storage container is shown in the drawing.

In the drawings, a container 1 is a basket-shaped container made of plastic or metal such as stainless steel, and is divided into an upper half 1a and a lower half 1b. The upper half 1a and the lower half 1b have interlocking locking means 2 and can be closed together, and by removing the locking means 2 the modifier can be taken in and out for exchange. Further, a chain 3 is attached to the upper half 1a, and by connecting this to the lid of a gasoline tank, for example, it can be easily taken out from the tank.

In addition to the embodiments shown in the drawings, suitable containers include plastic containers with pores, bags made of cloth or mesh, and the like.

[Example 1] An example of the method for producing a modifier for gasoline or the like according to the present invention will be described.

1. Preparation of P-5 acid 50 g of powder consisting mainly of calcium phosphate made from calcined animal bones was dissolved in fresh water IQ to obtain an aqueous solution with a pH of 13 or higher. Add 5% concentrated sulfuric acid to the aqueous solution, and
, 2 P-8 acid was prepared.

2. Separated seawater Add 10Q of the above p-s acid to 500Q of seawater,
After standing for a period of time, impurities were removed by filtration. As a result, the pH of the seawater became 1.6. Next, add 25Q of 3% sodium hydroxide aqueous solution to 500Q of low-PH seawater.
was added and left to stand for 10 hours.

At this time, the pH of solution (a) after filtering off the generated precipitate was 9.1.

3. Production of solid product After separating seawater, 10 (l) of solution (a) was heated to remove water to obtain a 1.5Q concentrated solution. This concentrated solution was rapidly cooled to form a precipitate. This precipitate weighed about 200 g.The remaining solution (b) 1k
g was further heated to remove moisture to obtain 170 g of solid material (c).

4. Production of modifier 50 mQ of ethanol was added to 100 g of solid material (c) and stirred. At this time, the two reacted with each other with heat generation to obtain a viscous solid substance, that is, the fuel atmosphere modifier of the present invention.

In order to increase the contact area with the fuel, 20 g of the fuel modifier obtained in this way was pulverized into the container shown in the drawing (capacity approx. 3
0+++Q). Such a modifier storage container is hung in each fuel tank of a gasoline vehicle or a diesel vehicle,
A driving test was conducted. As a result, the output was improved in all cases, especially when accelerating with a large load. Additionally, fuel efficiency has improved by approximately 20%. The results are shown in Table 2.

Table 2 The effect of the modifier of the present invention lasts for a running pressure of 13,000 to 5,000 km or about 1 month. When replacing it, you only need to remove the container from the fuel tank and replace only the modifier inside.

[Effects of the Invention] As is clear from the above examples, the gasoline modifier of the present invention increases the thermal efficiency of gasoline, etc., and has a great effect on improving output and fuel efficiency.

In addition, since seawater is used, it can be manufactured at low cost.

Furthermore, since it can be added while being stored in a container, there is no need to modify the engine or the like, there is no risk of clogging the fuel supply, etc., and replacement is extremely easy.
