Description of the invention: [Technical field to which the invention pertains] This case relates to novel catalyst powders, particularly for the production of carbon nanotubes (CNTs = carbon nanotubes). 5 [Prior Art] Tantalum fibers (nanocarbon tubes) having a diameter of 3 to 200 nm have recently attracted increasing interest in the world. The hollow fiber having the graphite structure is formed by a low molecular weight carbon compound permeating a catalytically active metal or a metal compound at 400 to 1100 ° C (preferably 450 to 700. Thermal decomposition of the crucible 10) (CCVD program = catalytic carbon) Vapor phase deposition procedure). The catalytically active metal is contacted with a gas barrier compound (especially a low molecular weight hydrocarbon) in a fixed bed (powder bed), a mobile fixed bed or a fluidized bed. The catalyst is in a calcination type in the reactor. In the initial stage of the reaction, the active site of the catalyst is reduced from the oxide to the metal. The diameter of the carbon nanotubes and carbon fibers is basically determined by the size of the catalytically active metal ruthenium particles. The size should be in the nanometer range, and in order to ensure that the catalyst can be treated, the latter is applied to a catalytically inert building material (usually an oxide ceramic) which is not reduced by hydrogen in the catalytic reaction, so that it forms a catalytically active metal. The surface of the surface is 2, wherein the size of the catalytically active metal determines the diameter of the fiber. A disadvantage of the CCVD process During the reaction, the CNTs yield per gram of catalyst depends on the starting 3 200948478 carbon compound, catalyst type, pressure, due to the formation of fibers that hinder the gas carbon compound from approaching the catalytic activity range. , structure, etc. Its structure and processing conditions such as: temperature, 1401763 B1 from fine fraction 5 10 15 aluminum is the gel drying and grinding, and in the mortar: acetic acid and: hydroxide: titanium, _ oxide, Gas oxides, 〇: 'There is also a catalytically active metal milk, ^, " two = sample is described. Support material and catalytic activity Jin Cao,: the same as 3 〇: 1. Based on the weight of the catalyst, reach up to The reset ratio is the yaw yield. Therefore, the catalyst must be removed in a complex: === ? In addition, 'in terms of the catalyst, so many orders: == = expensive: sub- and resulting in only a small proportion of catalytic activity Gold 4, and thus small carbon nanotube yield, based on the catalyst. WO 2006/050903 also discloses a single stage precipitation process for catalysts in which the support material and the active metal are each from the respective nitrates. Salt = solution co-precipitation. The teachings of this WO document are particularly concerned with catalytic activity: optimization of genus grades in order to achieve a south yield of CNTs based on the catalyst used ' cnTs with 5 to 350 times catalyst weight The yield, the read catalyst is achieved by using an active metal composition Mn_c〇 additionally containing Mo with MgO as a support material, wherein the active metal composition Μη-Co contains 60 mol% of active metal and 4 〇m〇1〇 /(^ supports metal. Therefore, it is not necessary to separate the catalyst in most applications. However, regarding the desired properties (renewable catalytic activity and size of the catalytically active range) for the manufacture of CNTs, catalysis Active metal and branch material 20 5 ❹ 10 15 ❹ 200948478 Co-precipitation control is difficult to test the mother liquor is expensive, this evening, the nitrate-containing self-precipitation reaction, hope to support the test is environmental reasons necessary. The particle size can first be used to feed the average flow in the microparticle range of the catalyst comprising the catalytically active metal, which is operable, that is, at least a few support materials and catalysts, and secondly, in the catalytic process, Initially, it is expected that the carbon compound can be made into a carbon compound, and the gas metal can be hydroxide ((SS touch)) even when the CNTs grow. Excessive sintering of the cutting material and purely active and hindering the second: the heat is converted into an oxide after the two-hearted ash, and the catalytic activity of the catalytic activity is controlled to be granules and cannot be expressed after the inclusion. The aim is to overcome the shortcomings of the prior art. ^ Catalyst (4) Single method 'The root of it = the invention' The catalytically active metal and the precipitate are in the respective positions and the chromium is not required to be intermediately tested. This; and the separate precipitated suspensions formed by the particle size can be made to "specially" catalytically active gold ueg A into the eighti, resulting in a uniform diameter of the carbon nanotubes, grain. The initial support method of the support material and the catalytically active metal of 77 is preferably carried out by a sulfate system, i.e., for use. The use of a chlorine-based compound as a sulphate aqueous solution results in a good product, and also does not relate to wastewater. 5 20 200948478 = particularly solution (especially ammonia and/or oxidized steel and/or sulphur-derived parent-formation - containing sulphuric acid) The ammonium-sink is fed into a zone in a joint container (joint ν_ι) with two zones to mix the salt solution and the base fluid (base S0luti0n) containing the catalytically active metal and the other zone for mixing the support material salt solution and the mother liquor or A further step-by-step base fluid. This can be used to control the conditions of the chamber, for example: for the pH of the slab of the active metal and for the slab of the support material. The two regions are each advantageously equipped with a stirrer. The tangential or countercurrent flow of the individual reaction solutions can be carried out, for example, by injection into individual reaction zones. The mixed region of the catalytically active metal is preferably less than 1/1 (10)', preferably less than 1/50 G, And container volume greater than 1/3_' has a relatively short residence time in the mixed zone of less than 1 minute. Precipitation of catalytically active metals may also be carried out in small reactors. The small reactor is in front of the main reactor and has a volume smaller than 1/100' of the main reactor, preferably less than 1/5 Torr. Here, in order to prevent the precipitated products of the catalytically active metal from sticking to each other, It must be quickly transferred to the main reactor. The appropriate catalytically active metal is a metal that forms unstable carbides, specifically Fe, Ni, Co, Cu, Mn, %, and Zn, and mixtures thereof. After precipitation, these metals It exists as a hydroxide or an oxyhydroxide. If it is further suitably modified by Mo in an amount of up to 1 〇 mol%, a mixture of WMn of 200948478 H to M molar ratio is particularly preferred. 5 e 10 15 ❹ Domain So that in the first; the two salt solution is introduced into the zone of the first-returner == the amount of the test solution of the night-in-law ===, 'the first agitation (four) zone = the zone 'high supersaturation leads to the catalysis ==.5. The natural generation of the nucleus of the j-degree of the first stirrer. In the first mixing ===, the particles of the hydroxide of the catalytically active metal can be reached; if necessary, oxygen or an oxygen-containing gas such as air, Can be injected into the area of the first agitator to cause simultaneous oxygen For example, c〇2+ to CoOOH or Μη2+ to Mn00H or Mn〇2. During this process, the particle size of the precipitated product can be controlled in the direction of finer particles. Preferably, the average diameter is 5 to 200 nm. a hydroxide of a catalytically active metal, particularly preferably 10 to 1 nanometer. The catalytically active metal is substantially completely precipitated in a very short two chambers and then mixed with a mother liquor of the precipitation reactor, wherein the hydroxide The concentration is reduced to less than 1/1 〇〇, preferably = 1/500, so that a hydroxide of a catalytically active ruthenium metal having a narrow particle size distribution can be obtained. The support metal salt solution is introduced to the second agitation. The area of the device and here mixed with the alkaline mother liquor causes precipitation of hydroxide of the supporting metal. Depending on the size of the desired metal oxide, it may be additionally fed into the test solution (as in the region of the first stirrer, preferably ammonia and/or sodium hydroxide solution). Enhanced supersaturation. Here, usually a pH of 8 to 11 is sufficient. The precipitation of the support material is particularly preferably carried out at a pH of from 9 to 10.5.
