摘要
具有高温室效应值的制冷剂面临淘汰,废弃制冷剂需要进行销毁处理。然而目前常用的销毁技术存在高能耗、产物有害等问题,因此需要寻找更为节能环保的降解技术。本文提出了一种新的制冷剂光热协同催化的降解方案,并对代表性制冷剂R134a进行了实验研究,探究了催化剂、温度、光强、反应组分等不同条件对降解反应的影响,并对其降解机理进行了推测。在本文实验条件下,R134a矿化率基本达到100%。
High GWP refrigerants are facing obsolescence.Scrap refrigerants also need destruction.However,the current commonly used destruction ways have high energy consumption and harmful products,which shows the necessity of finding an energy-saving and environmentally friendly destruction way.In this paper,photothermal catalytic degradation of refrigerant was proposed as a new route.Experimental studies were carried out on representative refrigerant R134a,including the influence of catalyst,temperature,light intensity and reaction components on the degradation reaction were investigated.The degradation mechanism was also speculated.Under the experimental conditions in this paper,the mineralization rate of R134a basically reaches 100%.
