均匀设计法在甲苯气相氧化催化剂制备工艺中的应用

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

应用均匀设计法研究甲苯气相氧化催化剂浸渍法制备工艺与催化剂活性的关系,结合回归分析,获得了实验范围内甲苯转化率和苯甲醛选择性与各因素的关系式,得到较好的浸渍法工艺条件.

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.
