すい。The results of this experiment can be explained as follows. In other words, as is well known, it has a large surface area (260~s o or
The base material of the support made of silica alumina with re/f) is effective in increasing the catalytic activity by reducing the particle size of the supported metal, but on the other hand, it has a strong solid acid strength, so it cannot be used during the catalytic reaction. Carbon-like substances tend to accumulate on the body.

あるニッケルとがスピネル型構造物（ＮｉＡ／２０４）
をつくりやすく活性度が低下するためである。Furthermore, free alumina in the silica-alumina and nickel as a catalyst form a spinel-type structure (NiA/204).
This is because it is easier to create and the activity decreases.

By forming a rectangular or cylindrical integrally molded body consisting of multi-layered thin walls such as the shape of the base material, and constructing a carrier by coating the base material with a colloidal inorganic heat-resistant material different from the base material, When a catalyst is supported, the respective drawbacks of the carrier and the catalyst can be compensated for, and a reforming catalyst body with high activity and long life can be produced.
またこのようなリフォーミング触媒体を炭化水素燃料改
質装置に用いることにより触媒作用が優れているので、
よりコンパクトな炭化水素燃料改質装置をつくることが
可能となる。In addition, when such a reforming catalyst body is used in a hydrocarbon fuel reformer, it has excellent catalytic action.
It becomes possible to create a more compact hydrocarbon fuel reformer.
