法を提供することにある。The catalyst carrier using recrystallized silicon carbide has the advantage of high porosity and low ventilation resistance, but has a specific surface area of 0.01 to 0.05 m2 / g.
Since it is small, it is difficult to carry a predetermined amount of catalyst when carrying the catalyst. Further, the recrystallized silicon carbide has a high firing temperature of 2000 ° C. or higher and is expensive. Further, the catalyst carrier using the silicic acid-bonded silicon carbide has a low porosity and a high ventilation resistance. Further, the specific surface area is too large, and even if a predetermined amount of the catalyst is carried, the catalyst carrier itself is exposed. Further, the alkali metal contained in the silicic acid used as the binder reacts with the catalyst to be supported and deteriorates the catalyst. In addition, there is a problem that the radial crushing load is small, and when the container is filled and used, it is damaged by its own weight. An object of the present invention is to solve the above problems, have a porosity and a specific surface area suitable for supporting a catalyst, do not deteriorate the catalyst by an alkali metal, and have a high radial crushing load. And to provide a manufacturing method thereof.

雰囲気中、還元雰囲気中のいずれでもよい。BEST MODE FOR CARRYING OUT THE INVENTION Properties required for an oxidation catalyst carrier are (1) porosity of 15% or more (2) specific surface area of 0.05 to 0.25 m2 / g (3)
That is, all the three items that the content of the alkali metal element is 0.4 wt% or less are satisfied. Porosity is 1
If it is less than 5%, ventilation resistance increases. If the specific surface area is small, a predetermined amount of catalyst cannot be supported. If the specific surface area is too large, the catalyst carrier itself is exposed even if a predetermined amount of the catalyst is carried, which is not preferable. In particular, when the content of the alkali metal element exceeds 0.4 wt%, regardless of the porosity and the specific surface area, the catalyst rapidly deteriorates in correspondence with the supported catalyst, resulting in a very low yield. In addition, if the radial crushing load is small, the catalyst carrier will be damaged by its own weight. In order to satisfy the above characteristics, it is desirable that the clay used in the present invention is a clay having an alkali metal content of 2 wt% or less, specifically Kibushi clay and / or frog eye clay. Colloidal silica has an alkali metal element content of 0.1 wt%
Below, 0.01 wt% or less is preferably used.
Silicon carbide contains almost none of these.
Here, the use of clay having an alkali metal content of more than 2 wt% is not preferable because the content of the alkali metal element in the catalyst carrier after firing exceeds 0.4 wt%. In a method for producing a silicon carbide based catalyst carrier, silicon carbide 76
˜90 wt% and clay having an alkali metal element content of 2 wt% or less and colloidal silica having an alkali metal element content of 0.1 wt% or less are 20 to 9 wt% and 0 respectively.
The reason why the content is 5 wt% is to maintain the high thermal conductivity and corrosion resistance of silicon carbide while increasing the formability of clay and lowering the firing temperature. The reason why the firing temperature is 1200 to 1500 ° C. is that if the temperature is less than 1200 ° C., the sintering does not proceed and sufficient strength cannot be obtained. Also, at temperatures above 1500 ° C., the porosity decreases. The atmosphere during firing may be the air, a neutral atmosphere, or a reducing atmosphere.
