- Patent Documents 1 to 4 relate to improvement of the contact area between the catalyst and a substance that is brought into contact with the catalyst to cause an oxidation or reduction reaction (hereinafter referred to as a reactive substance), or prevent bonding between the catalytic substances, although it has been disclosed for uniform dispersion and the like, no improvement has been considered for the catalyst support substrate.
- Patent Documents 1 to 4 although it can be understood that the area where the reactant is brought into contact with the catalyst is large to some extent, since the flow path formed in the honeycomb structure is linear, the catalyst substance and the reactant can be contacted. In order to improve the property and increase the reaction efficiency, it is necessary to lengthen the flow path, and it is difficult to make the structure small.
- Patent Documents 1 to 4 as described above, the reactant is present in the fluid, and the fluid is allowed to pass from one side to the other side. There was a problem that it was scarce, very brittle and vulnerable to impact. Further, in the case of a honeycomb structure made of a stainless steel thin plate, there is a problem that it is difficult to form a flow path smaller than a certain size, and the cost is increased.
- the problem to be solved is to produce a base material for a catalyst carrier that has excellent rigidity and further increases the contact possibility between the catalytic material and the reactant, instead of the honeycomb structure, and the granular material as the catalytic material.
- Manganese dioxide is easily crushed, easily absorbs moisture, and has the property of becoming liquefied if it absorbs too much moisture, and there is a problem in durability, and therefore, an alternative catalyst material is employed.
- the present invention is a catalyst having excellent durability and efficiency in place of manganese dioxide, which is currently generally used for reducing ozone gas, and producing a catalyst-supporting substrate having excellent rigidity and economy.
- a base material of the catalyst carrier is a porous body obtained by sintering a material composed of a single metal mesh or a material in which a plurality of metal meshes are laminated.
- a reduction catalyst carrier is obtained by forming an alumina thin layer in which a platinum group metal or oxide thereof, or a mixture thereof is dispersed and supported on the surface of the substrate.
- the present invention can secure a wide surface area of the alumina thin layer as a support by using a porous substrate, can freely select the pore diameter to some extent according to the amount of reactant contained in the gas, There is an advantage that the total thickness can be flexibly adjusted by the number of sheets.
- a plate-like porous body can be obtained by diffusion bonding, cutting and bending are possible, the degree of freedom of molding is high, and the amount of catalyst supported can be changed for each individual substrate. It is also possible to save expensive catalyst materials.
- the present invention for the reduction treatment of ozone gas, as a synergistic effect of the above advantages, the treatment efficiency of ozone gas is improved and the economy is excellent.
- FIGS. 1A and 1B are diagrams showing the results of experiments for confirming the effects of the present invention.
- the method for producing an ozone gas reduction catalyst carrier of the present invention comprises a catalyst comprising a porous body obtained by sintering a reduction catalyst carrier of ozone gas, a material made of a single metal mesh, or a material in which a plurality of metal meshes are laminated.
- An ozone gas reduction catalyst carrier is obtained by forming a thin alumina layer on which platinum group metals, oxides thereof, or mixtures thereof are dispersed and supported on the surface of the substrate.
- the catalyst material a platinum group metal, its oxide, or a mixture thereof can be selected. However, if the catalyst material is palladium metal, a simple substance of its oxide, or a mixture thereof, a suitable ozone gas reduction catalyst.
- a carrier is obtained.
- ozone gas reduction catalyst carrier of the present invention for example, a plurality of catalyst carriers are used as necessary, and ozone gas-containing gas is passed through each of them to efficiently reduce the ozone gas.
- a solution obtained by adding a platinum group metal nitrate powder as a catalyst material to an alumina sol solution is applied to the base material that has been previously roughened, or applied to the solution.
- the substrate is immersed and adhered, it is formed by firing at a temperature of 600 ° C. to 700 ° C. to produce an ozone gas reduction catalyst carrier.
- an alumina thin layer is similarly formed on the surface of the base material in advance without adding platinum group metal nitrate powder, and then immersed in a platinum group metal nitrate solution.
- the ozone gas reduction catalyst carrier is manufactured by baking with.
- the ozone gas reduction catalyst carrier produced in the present invention is used as follows.
- a porous material obtained by sintering a material obtained by laminating a plurality of metal meshes is used as a base material for a catalyst support, and a catalyst support in which an alumina thin layer is formed on the surface of the base material by dispersing and supporting platinum group metal as a catalyst material.
- a plurality of bodies are installed in a container, and a gas containing ozone gas is passed through the container to reduce ozone gas harmful to the human body into harmless oxygen.
- the reason why the sintered wire mesh is used is that the degree of freedom of opening is high.
- wire nets that are readily available in the market have abundant apertures ranging from 0.005 mm to 1 cm or more, and the apertures, rigidity, and porosity are different. This is because the material has excellent rigidity.
- the wires are firmly fused with the wires in contact with the individual wires, and there is an advantage that the wires are not displaced, that is, a stable open state can be secured even when stress is applied.
- the wire mesh used for the base material of the catalyst carrier is preferably made of, for example, a stainless material. This is because it has excellent corrosion resistance, is marketable, and is easily available. Of course, a wire mesh made of copper other than stainless steel, a copper alloy, nickel, or the like may be used, but the other metal to be mixed is preferably a material considering corrosion resistance.
- the SV value (l / h) obtained by dividing the reaction capacity (m 3 / hour) by the amount of filtration material (for example, 1 liter). ) Is preferably carried out at 1000 to 100,000 l / h. The reason is that if it is less than 1000 l / h, the catalyst becomes excessive, and its capacity cannot be fully used. If it is greater than 100000 l / h, the catalyst capacity is exceeded, and there is a high possibility that the reduction cannot be performed sufficiently. Because.
- the LV value (cm / sec) obtained by dividing the reaction capacity (m 3 / hour) by the area (m 2 ) is 10 to 200 cm / sec. It is desirable to do. The reason for this is that if it is less than 10 cm / sec, the catalyst does not function sufficiently and the efficiency with respect to the catalyst capacity is lowered, and if it is greater than 200 cm / sec, the catalyst capacity is exceeded and it becomes difficult to treat the entire amount.
- Palladium nitrate was added into an alumina sol solution, and the above-mentioned catalyst supporting substrate was immersed in this solution. Then, this was dried and fired at a temperature of about 650 ° C. in an air atmosphere. As a result, an alumina thin layer was obtained on the surface of the substrate, and at the same time, a catalyst carrier in which palladium, palladium oxide, or a mixture thereof as a catalyst material was dispersed and supported in the alumina thin layer was produced.
- the estimated thickness of the alumina thin layer was 0.005 mm, the palladium catalyst material particle diameter was about 10 to 20 nm, and the catalyst loading was about 1.7 g / liter of catalyst.
