Application of Uniform Design in Preparing Catalysts for Vapor Phase Oxidation of Toluene

Relationship between the impregnating method of preparing catalyst for vapor phase oxidation of toluene to benzaldehyde and the activity of catalysts is studied by using uniform design. Relational expressions between conversion rate, selectivity to benzaldehyde and processing parameters within the experimental range are derived and optimal impregnating parameters are determined based on regression analysis.
