、その熱分解反応が複雑であるので、極めて難かしい。(Prior art) To produce carbon black by the furnace method,
The first reaction zone of a generally cylindrical carbon black production apparatus is subsequently installed in which oxygen-containing gas and fuel are introduced axially or tangentially into the furnace, and the high temperature combustion mixture stream obtained by combustion of these gases is introduced into the first reaction zone. While moving the mixed stream to a second reaction zone, feedstock hydrocarbons are introduced into the mixed stream to produce carbon black. However, it is extremely difficult to produce carbon black with desired physicochemical properties in high yield because the thermal decomposition reaction is complicated.

。In particular, how the raw material hydrocarbon is mixed with the high temperature combustion mixture stream formed in the first reaction zone to produce carbine black in the second reaction zone depends on the physical properties (kind) and yield of the produced carbon black. However, in the past, the kinetic energy was increased by giving a strong swirl to the high-temperature combustion mixture flow.
Alternatively, attempts have been made through trial and error to form constricted portions of various shapes in the vicinity of the third reaction zone, which is the reaction stop zone. However, a fully satisfactory carbon black production method and apparatus have not yet been developed.

A method for producing carbon black with cross-feeding is described.

ックの製造が困難である。However, the shape of the furnace to which the combustor is attached is
Since the cross-sectional area increases toward the diaphragm (diaphragm), the turbulence obtained by the intersection of the combustion mixture flow decreases as it approaches the constriction. The turbulent energy and the turbulent energy obtained from the shape of the constriction are not effectively utilized. In addition, since the feedstock hydrocarbons are introduced in the axial direction of the furnace, the introduced feedstock hydrocarbons must diffuse in the radial direction of the furnace, and the feedstock hydrocarbons are concentrated in the area with the highest turbulence energy. Since it is not possible to rapidly introduce carbon black, it is difficult to control to obtain carbon black having any desired physical properties, and it is particularly difficult to produce carbon black with a small particle size.

失熱量が多くなり、エネルギー効率が低下する。Furthermore, in Japanese Patent Publication No. 62-10581, a plurality of carbine black intermediate gas flows generated in different series are caused to collide with each other. However, since the collision in this case is a collision between carbon black intermediate gas streams after introducing the feedstock hydrocarbon, the turbulent energy resulting from the collision is not useful for efficient production of carbine black. Furthermore, if the convergence of the carbine black intermediate product gas stream occurs in the collection of two or more first and second reaction zones, there is a possibility that the carbine black intermediate product has already been formed before the collection. As a result, the physical properties (quality) of the produced carbon black will vary significantly,
Furthermore, as the number of series to be assembled increases, the surface area of the production furnace body inevitably increases, so the amount of heat lost dissipated from the production furnace surface increases, resulting in a decrease in energy efficiency.

Therefore, feedstock hydrocarbons are introduced from these introduction nozzles into the region of the second reaction zone where (tK)min exists, which is formed by the collision and convergence-shaped reaction zone of the split streams, from a direction across the combustion mixture flow. The introduced raw material hydrocarbon quickly diffuses into the entire region where (tK)min exists, mixes, and produces carbon black very effectively, and the carbon is very effective in producing carbon black. The reaction can be easily controlled.

By controlling the manner of division and collision of branch streams, or the manner of introduction of feedstock hydrocarbons in relation to other conditions such as the flow rate of fuel and oxygen-containing gas, etc.
The physical properties (product type) of the produced carbon black can be controlled.

囲内から適宜に選択できる。The direction of feedstock introduction into the feedstock hydrocarbon nozzle is across the high temperature combustion mixture stream;
It does not necessarily refer only to the direction perpendicular to the flow of the hot combustion mixture. As shown in FIG. 6, the introduction direction of the feedstock hydrocarbon can be appropriately selected within a wide range of 20 degrees to 150 degrees with respect to the furnace axis.

This is because, in some cases, the physical properties of the produced carbon black can be controlled to a certain extent by controlling the insertion position of the raw material nozzle into the furnace.

。The reaction mixture stream in which carbon black has been produced in the second reaction zone as described above is then introduced into the third reaction zone 5 through the restriction section 2. The third reaction zone 5 is provided with a cooling water spray nozzle 7 according to a conventional method.
Cooling water is sprayed from this cooling water spray nozzle 7 to cool the reaction mixture and stop the reaction. The reaction product after the reaction has been stopped is further sent to a collection device such as a cyclone or a bag filter, and the produced carbon black is collected and collected.

ブラック生成反応を効率よく行なわせることができる。By using the production method and production apparatus of the present invention, it is possible to effectively generate a region where (tK)min exists in the second reaction zone, and a second region where (tg)min exists. By introducing the feedstock hydrocarbon into the reaction zone from a direction transverse to the flow of the high temperature combustion mixture, the carbon black production reaction can be carried out efficiently.

とが極めて容易となる。In addition, in particular, control (changes) of the division mode and collision mode of the high-temperature combustion mixture flow, control (changes) of the fuel flow rate and oxygen-containing gas flow rate, and in response to these controls, other controls such as the introduction position of the feedstock hydrocarbon, etc. By controlling the conditions, it becomes easy to control the physical properties (and therefore the variety) of the produced carbon black. For example, by arbitrarily controlling the particle size, particle size distribution, aggregate size, aggregate distribution, etc. of the produced carbon black, a carbon black that is suitable for blending in paints and resins with excellent blackness and color tone is produced. Alternatively, it becomes extremely easy to produce carbon blanks with excellent reinforcing properties such as rubber.
