Abstract

Sepiolite as catalyst carrier material, now commonly used in low temperature, for high temperature applications was very rare. ZrO2/sepiolite precursor was prepared by Chemical precipitation method, catalyst coating material was prepared at 600 , the samples were aged at 1000 . The powders with and without aging were characterized by means of BET (BET surface area), TG, XRD and SEM. The effect of acidification time on sepiolite surface area and the influences of Lanthanum adding, mass ratio of ZrO2 and sepiolite on the composite properties were studied. The results indicate that after acidification 18h sepiolite surface area up to 148.12 m2•g-1. When added 6 Wt.% La, mass ratio of ZrO2 and sepiolite was 3:2, ZrO2/ sepiolite catalyst coating composite surface area is maximum, reach to 95.7553 m2•g-1, with the 1000 aging, the specific surface area still up to 55.7553 m2•g-1, besides, it has good thermal stability. Compared with the specific surface area of sepiolite with high temperature treatment, this catalyst carrier coating composite improved significantly.
