ものである。Description: TECHNICAL FIELD The present invention relates to a method for producing a fuel additive containing aluminum as a main component, and more specifically, crude oil, petroleum pitch, kerosene, light oil, gasoline, regenerated oil, etc. The present invention relates to a method for producing a fuel additive which has good miscibility in fuel oil and which can maintain a low viscosity even when the content of aluminum is high.

で、添加剤としての充分な効果が期待できない。Most of these fuel additives are mixed with fine powders of inorganic materials such as inorganic metals, metal oxides, metal hydroxides, and carbonates in a solvent or water together with a dispersant containing a surfactant as a main component to form a slurry. However, if such a slurry is added to the fuel oil by precipitating or separating inorganic substances in the components during storage of the fuel additive, it may become a pipe part or burner. Part of it may settle and block,
The burner nozzle may wear. Further, when the dispersibility is poor and the particle size is large, the effect of contacting with harmful substances present in combustion flame, exhaust gas, and the like is insufficient, and a sufficient effect as an additive cannot be expected.

含有量が少ないという欠点がある。Further, conventionally, a fuel oil additive in which an oil-soluble metal compound is dissolved in a petroleum solvent or the like is also known. This fuel oil additive is uniformly mixed and dissolved with the fuel oil, and therefore has good stability, but has a drawback that the content of the metal component as an active ingredient in the oil-soluble metal compound is small.

As a result, only those containing about 0.1 to 0.5% can be obtained.

に上昇させることができる。On the other hand, JP-A-61-152794A discloses an invention relating to a fuel additive containing an oil-soluble powder composition as an active ingredient. This is a solution of alkaline earth compounds such as magnesium, calcium and barium in NaOH, KOH, NH 4 OH, Ca (O
H) The pH of the liquid is increased to 9 to 11 by adding an alkaline agent such as 2 and naphthenic acid, tall oil fatty acid, petroleum sulfonic acid, alkyl phosphate, olein are formed on the surface of the produced alkaline earth metal hydroxide. An acid, lauric acid or the like is adsorbed to produce an oil-soluble aggregate, which is further washed with water for desalting, and dehydrated and dried to obtain a powder composition, which is used as an active ingredient of a fuel additive. The powder composition obtained by this method has good dispersibility in oils, and the content of the Al component can be increased to about 3%.

る。(Problems to be Solved by the Invention) However, when the aluminum-containing fuel additive is produced by the above-mentioned method, the pH of the aluminum compound aqueous solution is 9 to 11
Since most of the aluminum compounds are dissolved as aluminate because it is on the alkaline side, Al (OH) with a small particle size
Only 3 particles can be obtained, and naphthenic acid and the like are adsorbed around the small particles of Al (OH) 3 to form an oil-soluble powder composition. Small Al
When a composition composed mainly of (OH 3 ) particles is dispersed in oils, the viscosity of the fuel additive becomes high, so the content of Al component in the fuel additive is limited to about 3%. is there.

の粉体組成物収量を低下させてしまう。In addition, since most of the aluminum compounds are aluminate, many particles that are insufficiently adsorbed are present. Therefore, in the step of washing the oil-soluble aggregate with water, those particles flow out to make the washing wastewater cloudy, or the yield of the powder composition after washing and dehydration drying is reduced.

しまう場合がある。Furthermore, if particles having insufficient adsorption are contained in the powder composition,
When this powder composition is dispersed in oils, the Al component may be solidified in the form of pudding and lose its fluidity even at this low concentration.

It is an object of the present invention to develop a method for producing a fuel additive that can maintain a low viscosity even when the content is as high as about 10% and does not solidify into a pudding.

Since (OH) 3 is ultrafine particles called hydrosol, it is possible to maintain a low viscosity even with a high content of Al component as described above, and to produce a fuel additive that does not solidify into a purine form. , Al (OH) 3 has a particle size of several tens to several hundreds of Å, and it is necessary to completely adsorb naphthenic acid and the like to each of the particles.

される。(Effect of the invention) As described above, in the present invention, ammonia water is added to an aqueous solution of a water-soluble salt of aluminum to adjust the pH of the solution to 6 to 9 to produce an aqueous suspension of aluminum hydroxide. After sufficiently heating the water suspension of aluminum hydroxide, add an adsorbent, an oily non-polar solvent, and an O / w emulsion consisting of water and ammonia.
Since the pH is set to around 6 to 9 neutral,
Unlike the method disclosed in Japanese Patent No. 15274, there is no formation of aluminate, and only aluminum hydroxide is formed. Furthermore, excess ammonia gradually evaporates with heating,
The pH of the liquid is kept near neutral, and the growth of Al (OH) 3 particles produced by the coexisting action of ammonium salts is promoted.

濾過及び洗浄の工程が非常に容易になる。On the other hand, in the water suspension of grown Al (OH) 3 particles, as described above, the adsorbent, the non-polar solvent and the ammonia water are used.
w When an emulsion is added, the emulsion disperses very uniformly in the water suspension, and eventually the adsorbent substance is chemically adsorbed on the surface of all Al (OH) 3 particles to form an active monomolecular adsorption layer. The non-polar solvent and the remaining adsorbent are physically adsorbed around the adsorbent to form a bimolecular adsorption layer. And
By adding a non-polar solvent to the Al (OH) 3 particles, the surface becomes more lipophilic, and eventually large oil-soluble aggregates having a diameter of about 1 to 2 mm are obtained. As a result, the steps of filtering and washing the aggregates are greatly facilitated.

に、洗浄排水は白い濁りがなく、無色透明になる。Further, in the present invention, most of aluminum water-soluble salts are Al
It becomes (OH) 3 particles, and the adsorbent is surely adsorbed on the surface. That is, unlike the method disclosed in Japanese Patent Application Laid-Open No. 61-152794, a large amount of insufficiently adsorbed particles exist around aluminum particles due to the formation of aluminate. Therefore, particles are not adsorbed insufficiently even in the washing step for desalting, the yield of aggregates can be increased, and the washing waste water becomes colorless and transparent without white turbidity.

極性溶剤で構成される二分子吸着層で被覆され、直接空
気と接触することが妨げられているため、乾燥時の発火
現象がなくなり、したがって高温乾燥が可能になる。Furthermore, since the monomolecular adsorption layer composed of the adsorbed substance of the agglomerates is covered with the bimolecular adsorption layer mainly composed of a non-polar solvent, which prevents direct contact with the air, the ignition phenomenon during drying occurs. High temperature drying is possible.

ができる。On the other hand, since the agglomerate powder obtained by drying is coated with a bimolecular adsorption layer mainly composed of a non-polar solvent on the surface, it is extremely difficult to produce a fuel additive in addition to oils. It can be easily dispersed, the time required for the dispersion step can be shortened, and the fuel additive can be manufactured at low cost.
また、この発明ではアルミニウム水溶性塩の殆どがAl

加剤中のアルミニウム含有量を高めても、燃料添加剤の
粘度上昇を抑制することができる。Further, in the present invention, most of aluminum water-soluble salts are Al
Since it becomes (OH) 3 particles and is aged, the particle size of Al (OH) 3 particles becomes extremely large as compared with the particle size disclosed in the above-mentioned JP-A-61-152794. Therefore, even if the aluminum content in the fuel additive is increased, the increase in viscosity of the fuel additive can be suppressed.
更に、この発明によって得られた凝集物粉体中には吸着
不充分な粒子が含まれていないため、油類中に混合分散
させた時も、プリン状に固化する現象を防止できる。Further, since the aggregate powder obtained by the present invention does not contain particles that are not sufficiently adsorbed, it is possible to prevent the phenomenon of solidification into a pudding even when mixed and dispersed in oils.
