摘要
对微波煅烧硫酸工业用钒催化剂进行了研究。实验结果表明,采用多模微波在600℃下煅烧30 min,钒催化剂耐热后活性大于85.50%,径向抗压为119 N/cm,磨耗率为6.07%,堆密度为0.63 g/mL,各项指标均达国家标准。并利用X射线衍射仪、扫描电子显微镜对微波煅烧后钒催化剂产物进行分析表征。
Calcination of vanadium catalysts for sulphuric acid industry by multimode microwave is studied in this paper. The results show that when vanadium catalyst is calcinated by multimode microwave for 30 minutes at 600℃, the activity after heat-resistant of vanadium catalysts is greater than 85.5% ,and the radial compression, abrasion rate and pile density are 119 N/cm,6. 07% and 0. 63 g/mL, respectively. All indexes of vanadium catalyst can reach the national standards. The influences of multimode microwave calcination on microstructure of vanadium catalyst are characterized by XRD and SEM.
