摘要
在流向变换催化燃烧小型中试装置上利用国产催化剂进行了含混合芳烃模拟工业废气的净化试验 ,重点考察了挥发性有机物 (VOCs)能够通过调整换向周期在既不“飞温”也不“熄火”的条件下保持很高的VOCs转化率的浓度变化范围 ,初步观察了由于VOCs浓度过高或过低所引起的“飞温”或“熄火”
In a pilot scale reverse flow reactor with a liter of catalyst, catalytic combustion of typical industrial waste gas contaminated with volatile organic compounds (VOCs) was systematically investigated, and the temperature run-away in the case of too high feed concentration and the extinction of reactor in the case of low feed concentration were observed. More attention was paid to determining the range of feed concentration in which through adjusting operation parameters, such as the periodic time, the reactor could achieve a high conversion of VOCs and meanwhile maintain a stable ignited state, i.e neither temperature run-away nor extinction.
