Definitions
- the present invention relates to a method for producing a film catalyst suitable as a catalyst for gas-liquid reaction.
- a film catalyst in which a catalyst is supported on a film substrate is known (WO 2 0 0 5/0 3 5 1 2 2).
- this film-like catalyst is sometimes processed and formed into a honeycomb shape in the form of a corrugation.
- the catalyst layer carried on the base material is wrinkled by contact with the forming tool. There is a problem that it may occur or, in some cases, the catalyst may fall off partially.
- JP-A 8-1 4 1 3 9 3 a metal base material having a catalyst layer was sandwiched between flexible plate-like members, and then passed between a pair of synthetic resin gears to form a corrugated shape. Thereafter, a method of heating a metal substrate is described, and it is described that a catalyst body is processed by sandwiching a high-quality paper as a flexible plate-like member with a polyethylene resin.
- a plate-shaped member When such a plate-shaped member is used, the stress acting on the catalyst layer cannot be sufficiently relaxed in the meshing space between the gears, and the catalyst layer may be damaged. Further, in the space for meshing between the gears, the pressure applied to the catalyst layer and the plate-like member increases, so that stress is applied to the synthetic resin gear and the durability of the gear is impaired. Also travel If wrinkles occur in the plate-like member at times, the total thickness of the plate-like member substantially increases at the wrinkled portion, so a very large stress is applied to the catalyst layer, and mechanical destruction of the catalyst layer cannot be avoided.
- JP-A 2000-1 898 14 describes a method of press molding with a molding apparatus using a mold for thermoforming a catalyst coated body in which a catalyst component is coated on an inorganic fiber or a net-like body.
- a molding apparatus is described in which a flexible porous layer is provided on the surface of a mold.
- the present invention comprises a step of forming a catalyst layer on one or both sides of a support to produce a film-like catalyst, and a step of bending the film-like catalyst.
- a bending tool two gears disposed so as to face each other are used as a bending tool, and between the catalyst layer of the film catalyst and the two gears.
- This is a method for producing a film-like catalyst, in which bending processing is performed with a protective material having a compression ratio of 40 to 95% interposed therebetween.
- the ratio (t 2 ti) of the thickness of the film-like catalyst (t and the total thickness (t 2 ) of the protective material is 4 to 20; And the relationship between t 2 and t 2 is t, ⁇ T ⁇ tt 2 where T is a combination of the gears of the two gears. The distance between the gears, with the distance close to the shortest distance as the zero reference.
- the present invention comprises a step of forming a catalyst layer on one or both sides of a support to produce a film-like catalyst, and a step of pressing and bending the film-like catalyst.
- the bending tool includes two upper and lower plate-shaped bending tools, and the two plate-shaped bending tools have corrugated teeth on a flat plate, The concave and convex portions of the corrugated teeth are arranged so as to overlap with each other.
- the catalyst layer of the film catalyst and the bent portion are bent.
- JP—A 2 0 0 0— 1 8 9 8 1 4 suppresses the wear of the mold metal itself.
- the surface porous layer provided on the mold should have strength and durability. It was difficult. When stress is applied to the mold and the porous layer during molding, stress is concentrated at the interface, causing separation between the porous layer and the mold. Therefore, it was difficult to fix it permanently, that is, it was difficult to have durability in molding use.
- the porous layer has a high friction coefficient, which causes problems such as damage to the catalyst body due to the frictional force applied to the catalyst body.
- the present invention provides a method for producing a film catalyst that can be processed into a desired shape without damaging the catalyst layer.
- a film catalyst processed into a desired shape can be obtained without damaging the catalyst layer.
- the method for producing a film catalyst of the present invention is used as a catalyst for various organic synthesis reactions. It can be used as a method for producing a film catalyst.
- the protective material preferably has a dynamic friction coefficient of 0.05 to 0.25, or the protective material is a nonwoven fabric.
- a catalyst layer is formed on one surface or both surfaces of a long support to manufacture a long film catalyst.
- the first production method is suitable for processing a long film-shaped catalyst, but can also be applied to processing a film-shaped catalyst of each desired shape.
- the coating composition used for the production of a long film catalyst can be prepared as follows.
- a catalyst active material or a catalyst in which a catalyst active material is supported on a porous material can be used as the powdered catalyst contained in the coating composition.
- the catalyst active material may be any component that is effective for the applied chemical reaction,
