【摘要】研制筛选出组成为Fe2O3-GeO2-SiO2-K2O复合催化剂,确定较优化的制备条件、反应条件和再生方法。单管放大试验表明,该催化剂具有操作条件温和、反应活性及选择性高(间甲酚转化率接近100%,2,3,6-三甲基苯酚选择性96%以上)、使用寿命长(3 000 h以上)、操作性能稳定、操作弹性大和易于再生等综合性能,适合于工业生产。更多还原

【Abstract】 Fe2O3-GeO2-SiO2-K2O catalyst was prepared and the optimum preparation condition,reaction condition and regeneration method were investigated.The bench-scale experiment showed that the catalyst had mild operation condition,high activity(nearly 100% conversion),high selectivity to 2,3,6-trimethylphenol(96%),long service life(over 3 000 h),stability in operation,operational flexibility and ease in regeneration.更多还原
