DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zeolite molded article used as an adsorbent, a catalyst, a material for separation, and the like. As an adsorbent for drying sulfur gas, air for vehicle air brakes, etc., an adsorbent such as nitrogen compounds in wastewater and radioactive substances in radioactive wastewater, or as a catalyst supporting various metals by supporting various metals The present invention relates to a method for producing a zeolite molded body mainly used in the field of petrochemical industry and the like.

[0002]

2. Description of the Related Art Conventionally, zeolite has been obtained by a hydrothermal synthesis method in which an alkaline mixed solution containing a fine powder such as silica gel or silica sol as a silicon source is heated under high pressure conditions to precipitate a zeolite powder. The zeolite powder obtained by this method had almost no plasticity or caking property. Therefore, when a zeolite molded body is obtained, a zeolite powder is prepared by adding an appropriate inorganic binder, inorganic fibers, water, etc., and then extruded, dried and sintered.

Here, as the inorganic binder, clay minerals such as sepiolite, kaolinite and montmorillonite (kaolin-based clay, montmorillonite-based clay, formite-based clay, illite-based clay, etc.), silica sol (colloidal silica), Inorganic sols such as alumina sol and silica-alumina sol are used, and as the inorganic fibers, non-oxide fibers such as carbon fibers (carbon fibers), oxide fibers such as silica fibers, and other steel fibers Metal fibers and the like were used.

[0004]

However, since the inorganic binder and the inorganic fibers do not have a catalytic activity or an adsorptive ability, the resulting molded article has an adsorption property derived from the porous structure of zeolite. Physical properties such as activity and catalytic activity tended to be low.

Accordingly, an object of the present invention is to provide a zeolite molded article without adding the inorganic binder or the inorganic fibers in view of the above prior art, that is, to obtain a zeolite component containing no inorganic binder. An object of the present invention is to provide a method for obtaining a 100% zeolite molded body.

When the O ₂ ) component and the crystallization modifier coexist (mixing step), in the inorganic material mixture in which the crystallization modifier coexists, the inorganic material aggregates around the crystallization modifier. Composite microparticles are formed, for which the composite microparticles can be isolated as a solid component by a solid-liquid separation step,
A crystalline microporous intermediate can be obtained. The structure of the crystalline microporous intermediate is that the SiO ₄ tetrahedron is 2
A layered structure formed by dimensional bonding, holding water molecules between the layers of the layered structure and attracting water molecules to the layer surface of the layered structure to form a water film. It is considered to be a layered structure.

[0008] The crystalline microporous intermediate has a higher cohesive force than fine particles obtained by a conventional hydrothermal synthesis method,
By adding an organic binder and distilled water to the crystalline microporous intermediate, a crystalline microporous intermediate raw material excellent in cohesiveness and plasticity can be further obtained (raw material clay) Manufacturing process). This excellent caking and plasticity is that the organic binder surrounds the crystalline microporous intermediate having a hydrated layered structure, and the layered structures of the crystalline microporous intermediate form a slippery state. It is thought that it is obtained by doing.

[0009] Since the crystalline microporous intermediate precursor material is excellent in caking property and plasticity, it can be extruded even if it has a complicated shape such as a honeycomb shape, and has good formability and crystallinity. A microporous intermediate molded product can be obtained (molding step).

By subjecting the crystalline microporous intermediate molded body to a heat treatment step consisting of drying, crystallization, and firing,
A zeolite molded body can be obtained. That is, since the contained water is removed by drying the crystalline microporous intermediate body, a dense structure is formed only in the space from which the water molecules have been removed (drying step). Since it is crystallized, it passes through the layer of the organic binder coated around the layered structure of the crystalline microporous intermediate during crystal growth, thereby promoting the bonding between silicon dioxides ( Crystallization step). Then, by firing, the organic binder can be eliminated (firing step), and a zeolite molded article composed of 100% zeolite can be obtained.

Therefore, even after the zeolite molded article is fired and the organic binder is burned off, the zeolite molded article made of 100% zeolite according to the present invention does not collapse even without a binder and maintains a predetermined strength. It is possible to do.

It is preferable that the organic binder is added in an amount of 5 to 15 parts by weight based on 100 parts by weight of the crystalline microporous intermediate. That is, when the amount of the organic binder is 5 parts by weight or less based on 100 parts by weight of the crystalline microporous intermediate, the amount of the organic binder is small, and the plasticity of the crystalline microporous intermediate raw material clay is reduced. In short, extrusion of a complex shape such as a honeycomb becomes difficult. Conversely, if the amount of the organic binder is 15 parts by weight or more with respect to 100 parts by weight of the crystalline microporous intermediate, the amount of the organic binder is too large, and the crystalline microporous intermediate molded body is protected. Since the organic binder around the periphery of the layered structure of the crystalline microporous intermediate is excessively adhered, the coating of the organic binder during the crystallization in the crystallization step is reduced. And the formation of a network with the surrounding silicon dioxide becomes difficult, and the crushing strength of the final product is impaired. In consideration of the easiness of burning out the organic binder in the firing step, the organic binder is added in an amount of 5 to 10 parts by weight based on 100 parts by weight of the crystalline microporous intermediate. Is more preferable.

If the organic binder is a polysaccharide, it surrounds the crystalline microporous intermediate and forms a slippery state between the layered structures of the crystalline microporous intermediate. Caking properties of the porous intermediate raw material
Since the plasticity is easily improved and the polysaccharide is easily burned, it can be easily eliminated in the baking step.

[0016]

As a result, even if it has a complicated shape such as a honeycomb shape, it has a predetermined strength and is hardly collapsed.
A zeolite molded body composed of zeolite was obtained. Further, since the zeolite molded body is made of 100% zeolite without containing an inorganic binder, the performance per unit weight (catalytic ability, adsorptive ability, etc.) is improved as compared with that obtained according to the prior art. Especially in the field of catalysts,
The benefits are thought to be immeasurable, as a few percent binder loss leads to a dramatic improvement in catalyst activity.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for producing a zeolite molded article according to the present invention will be described below with reference to the flowchart shown in FIG.

[0018] A (Intermediate Production process) kanemite (ideal composition _{formula: NaHSi 2 O 5 · 3H 2} O)
A mixing step is performed in which a silicon dioxide (SiO ₂ ) component such as fine particles and a crystallization modifier coexist. Then, by performing a solid-liquid separation step of isolating, as a solid component, the composite fine particles precipitated in the mixed inorganic material liquid obtained in the mixing step, a crystalline microporous intermediate is obtained.

B (raw material filling clay production process) An organic binder composed of a polysaccharide or the like is added to the crystalline microporous material intermediate, and a dry mixing process of mixing in a dry manner is performed. This gives a homogeneous powder mixture. And
Distilled water is added to the powder mixture, and a water-kneading step of kneading the mixture with a three-roll mill or the like is performed to obtain a crystalline microporous intermediate precursor material clay. Thereby, the organic binder is dispersed in the crystalline microporous intermediate precursor raw material clay,
A uniform and minimal amount of an organic binder is mixed with the particles of the crystalline microporous body intermediate powder to prepare a crystalline microporous body intermediate raw material clay having plasticity sufficient for extrusion molding.

When water is directly contained in the organic binder, only the surface of the organic binder powder is wetted with water to form partially-agglomerated pseudo-agglomerated particles, which tends to take time to disperse. is there. Further, fine ceramics powders such as crystalline microporous intermediates used in the present invention are insoluble in water and are in the form of fine powders of about 5 to 20 microns.
If this is mixed with distilled water first, the powder particles tend to concentrate on each other to form aggregates, which tends to take time to disperse. Therefore, in order to efficiently obtain the crystalline microporous material intermediate raw material, first, the crystalline microporous material intermediate and the organic binder are mixed (dry mixing method), and then the distillation is performed. By mixing and kneading with water (water kneading step), the powder can be uniformly wetted and the kneading time can be shortened.

C (Molding Step) By extruding the above-mentioned crystalline microporous material intermediate raw material clay, a crystalline microporous material molded product can be obtained. The zeolite molded article according to the present invention may of course have any shape. For example, in addition to the honeycomb, shapes such as a granular material, a spherical material, a round bar, a square bar, a tube, and a thin plate can be used. In particular, it is possible to obtain a molded article having a complicated shape such as a honeycomb structure without using an inorganic binder by taking advantage of good moldability.

D (Heat treatment step) The crystalline microporous intermediate molded body obtained in the molding step is dried with warm air at 80 to 100 ° C for about 5 minutes to remove excess water. The compressive strength of the crystalline microporous intermediate body can be increased (drying step). This has the effect of increasing the mechanical strength and crushing strength of the final product by subjecting the crystalline microporous body intermediate molded body to drying shrinkage once to increase the molded body density and subjecting it to the crystallization step described below.

The crystalline microporous intermediate product after the drying step can be crystallized at 150 ° C. for 40 hours under solid-phase reaction conditions (crystallization step). Next, by heating at 500 ° C. for 1 to 2 days, a zeolite molded body can be obtained while burning out and removing the organic binder (firing step).

The crystallization controlling agent plays a role as a "template" in forming zeolite pores in the crystallization step, and therefore, the molded product obtained in the crystallization step is required. Is a state in which the crystallization modifier is still blocking the zeolite pores, and sintering the zeolite so as not to burn it out does not make full use of the catalytic performance of the zeolite inherently porous. Further, the organic binder functions as a "binder" and a "plasticity-imparting / enhancing agent" for enabling the extrusion of the crystalline microporous intermediate raw material clay in the molding step. So,
In the baking step, it is necessary to "burn off" the organic binder.

Further, in many zeolites, when the temperature exceeds 1000 ° C., the skeleton structure is destroyed, so that the pore structure is damaged, and the original performance tends to be unable to be exhibited. Therefore, in the firing step, the firing temperature control program is set to a slow heating rate of about 5 ° C./hr, and the maximum firing temperature is maintained at 700 ° C., more preferably at 500 ° C. for 1 to 2 days. Perform baking. As a result, the organic binder can be burnt away and sufficiently removed, and in addition, cracks due to gas generation when the organic binder scatters can be prevented.
