Co shift catalyst carrier, catalyst based on the catalyst carrier and preparation process thereof

Abstract

The present invention provides a catalyst carrier with shift and adsorption purification performance, comprising modified bauxite in the raw material components which fluxing and pore forming effects. Most iron oxide contained in the bauxite is removed after modification, so that there are a large amount of highly active aluminosilicate compounds in the modified bauxite. When preparing the catalyst, the aluminosilicate compound serves as a low melting point flux and can significantly increase the migration rate of magnesium and aluminum ions during the calcinating process and promote the generation of MgAlOat low temperatures, thereby the catalyst carrier of the present invention has strong anti-hydration capacity and mechanical strength. In addition, when the modified bauxite is used as macroporous hard template for the preparation of the catalyst, macro pores can be formed in the structure of the catalyst carrier after calcinating treatment, so that the catalyst carrier of the present invention has strong adsorption purification ability on macromolecular particles including oil pollution and dust.
