摘　　要：2021年9月《蒙特利尔议定书》基加利修正案对我国正式生效,我国在未来三十年左右将面临严峻的HFCs淘汰任务,因此实现淘汰HFCs的高效率、低能耗降解至关重要。传统的高温焚烧工艺存在能耗高、成本高的特点,因此本研究关注于制冷剂热催化降解方法,选取主要的HFCs类制冷剂HFC-134a为研究对象,通过实验手段和量子化学计算方法探究HFCs制冷剂的热催化方案可行性,并分析了催化剂种类、温度和氧气比例等关键因素对制冷剂降解效果的影响。With the Kigali Amendment to the Montreal Protocol coming into effect in September 2021,China faces a challenging task of phasing out HFCs in next few decades.The efficient and low-energy degradation of HFCs is therefore of utmost importance.This study focuses on the thermal catalytic degradation of refrigerants and investigates the feasibility of using this method to degrade HFC-134a,a major HFC refrigerant,through experimental and quantum chemical calculation methods.The study also analyzes the impact of key factors such as catalyst type,temperature,and oxygen fraction on refrigerant degradation efficiency.
