Title:
CERAMSITE CATALYST CONTAINING METALLIC OXIDE PARTICLES, AND PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/206042
Kind Code:
A1
Abstract:
The present invention relates to the technical field of preparation of a ceramsite catalyst and disclosed are a ceramsite catalyst containing metallic oxide particles, and a preparation method and an application thereof. The preparation method comprises the following specific steps: dissolving metal salt with ozone catalytic activity in water to obtain a metal salt solution; mixing the metal salt solution with a ceramsite raw material to prepare a ceramsite embryoid body; and sintering the ceramsite embryoid body at a high temperature to obtain the ceramsite catalyst containing metallic oxide particles. The ceramsite catalyst containing metallic oxide particles in the present invention can be repeatedly used, so that secondary pollution is reduced; and with a same ozone input quantity, the ceramsite catalyst containing metallic oxide particles in the present invention is added, so that the efficiency of water treatment through ozone oxidization is improved by 41.35%.
