Influence of the Two Metal Dopant Improves the Specific Surface Area of Alumina in Catalyst Support

Abstract:

The study of this paper is La and Ba(La⁄Ba=1:1) doped modifying alumina. And we focus on the need for influence on content(La+Ba) and calcination temperature on the S.A of modified alumina. Factors considered were the S.A, it’s attenuation and phase in calcined etc. Screening out the sample of better comprehensive performance. At the same time the less content(La+Ba) can reduce the manufacturing cost of the catalyst.
