Title:
シリカアルミナを含む新規な構造体、およびその製造方法
Document Type and Number:
Japanese Patent JP5333373
Kind Code:
B2
Abstract:

To provide a new structure containing silica alumina having catalytic activity, which is effective as a catalyst, and a method of producing the same.

The new structure is provided by supporting a hydroxide and/or oxide, which serves as the raw material of the silica alumina, on the surface layer of a carrier, and then by firing at 200-800°C. In the new structure, the silica alumina having catalytic activity is present in the surface layer of the structure, particularly, the surface layer to the depth of 1-1,000 μm from the outer surface of the structure. The inner layer excluding the surface layer of the structure is composed of the carrier containing substantially no silica alumina having catalytic activity.
