摘要
介绍了整体式WSH-5催化剂对挥发性有机化合物(VOCs)的催化氧化活性和工业应用。实验室条件下催化剂活性评价实验表明,WSH-5催化剂对苯等VOCs的高效转化温度(转化率>98%)在210~300℃之间,较WSH-2催化剂降低了5~40℃。工业废气治理应用表明,WSH-5催化剂对橡胶废气和炼化污水场挥发性废气的VOCs去除效果良好,净化率可达97%以上,净化后废气污染物浓度满足国家和地方排放标准。
Abstract
This paper introduces catalytic oxidation activity and industrial application of monolithic WSH-5 catalyst in treating with volatile organic compounds (VOCs).Catalyst activity evaluation under test conditions indicates that the conversion of VOCs such as benzene over WSH-5 catalyst can exceed 98% at a temperature range of 210-300℃,which is 5-40℃lower than the temperature at that the same conversion can be achieved over WSH-2 catalyst.Industrial application results demonstrate that WSH-5 catalyst show good removal efficiency to VOCs from both rubber waste gas and waste gas in refinery wastewater treatment plant,with a removal rate over 97%,and the pollutant indexes of purified gas can satisfy China's national and local emission standards.
