An antisulfur CO shift catalyst was prepared from supporter of activated alumina, which was of our own make from a bauxide,by coimpregnation.

The data of the experiment, the reaction constant of the coimpregnation and the Freundlich's adsorption isothermal equation in which the active components are adsorbed on to the carrier, have been obtained by the regresion analysis.

Three methods for preparing hydrotreating catalysts, such as dry mixing (DM), dry mixing followed by impregnation (DM I) and co impregnation (CI), were compared.

Using cobalt salt,aluminum salt or titanium salt as modifying agent,the metallic ion doped silica gel adsorbents based on ceramic fiber are prepared by treating ceramic fiber paper with impregnation coprecipitation of water glass and aqueous solution of acidic metallic-salt sequentially.

The solid surperacid SO42-/TiO2-Fe2O3 was prepared by the method of coprecipitation and wet impregnation.
