摘要
在处理含硅有机废气的过程中,由于分解产物覆盖贵金属催化剂活性位点,从而导致催化剂失活.若开发预处理剂,安装在贵金属催化剂前端,可吸附、锚固Si物种,从而保护后端贵金属催化剂,延长VOCs催化剂寿命.本研究利用浸渍后涂覆制备预处理剂,并对样品的效果进行分析,分析结果表明该方法可延长贵金属使用寿命50%以上.
Abstract
In the process of treating silicon containing organic waste gas,many precious metal VOCs oxidation catalysts are poisoned by Si species covering it's active sites after organosilicon decomposition,resulting in catalyst deactivation.If a pretreatment agent can be developed to be installed at the front end of the precious metal catalyst bed for adsorption and anchoring of Si species,it can protect the rear end precious metal catalyst and extend its lifespan.This study prepared a pretreatment agent by impregnation followed by coating,and evaluated the effectiveness of the sample.The results showed that the pretreatment agent can extend the lifespan of precious metal catalysts by more than 50%.
