摘要
本文合成了一种新型的Pt负载在Al_2O_3涂膜强力富硅纤维载体的催化剂,研究低温下催化易挥发有机化合物的行为.用四种有机化合物检验实验参数对催化剂分解有机化合物分解率的影响.讨论了流速、浓度、有机物的本性、预热温度、反应热等参数的影响,并给出了催化剂对苯、甲苯在特定实验条件下的活化能、反应级数和指前因子的数值.
Catalytic Oxidation is a useful process to destroy VOC emissions in air. A new ty] catalyst, Pt supported on high intensity enrich silicon fibre with A12O3 thin coating filn has been studied for the deep oxidation of VOCs in low temperature. Four organic cor pounds were tested and discussed the influences of operating parameters to the conve sion of VOCs, they are such as space velocity, concentration, VOCs nature, the temper ture of preheater and the energy of reaction etc. , the pre-exponential factor, activatic energy and reaction order of both benzene and toluene for this catalyst at particular co ditions have been given.
