摘要:
以硝酸钴﹑海泡石为原料,采用浸渍法,制备用于环己烷氧气氧化反应的Co3O4/海泡石催化剂。考察了盐酸浓度、反应温度、时间、引发剂加入量、催化剂用量对催化性能的影响。在最优条件下所制得的催化剂用于环己烷氧化转化率为13.2%,环己酮(KA油)选择性为77.8%。同时,以还原态钴为研究对象,借助模拟软件简要分析了海泡石负载和载体酸处理对催化剂性能的影响。
Abstract:
Co3O4/sepiolite catalyst for cyclohexane oxidation was prepared by dip-molding method with cobalt nitrate and sepiolite. The impact of hydrochloric acid concentration of acid treatment, reaction temperature, reaction time, initiator concentration, catalyst concentration to catalyst performance were studied. The conversion rate of cyclohexane reached 13.2% and the selectivity of KA was 77.8% under the best preparation and reaction conditions. Analyzing reducible Co only, simulation software was used to build models to analyze the effect of sepiolite support and acid treatment on catalyst performance.
