Abstract:

Pd-Cu/activated carbon catalysts were prepared by wetness impregnation and their performance in the room-temperature catalytic oxidation of the pulse reaction of carbon monoxide were investigated using simulated cigarette smoke gas consisting of 4.4 CO-4.2 H2O-19.2 O2-72.2 He (volume fraction, %). The effect of different activated carbon supports on catalytic performance was investigated in detail. The results show that at room temperature the order of catalytic performance for CO oxidation is: the catalyst supported on coconut activated carbon (CAC)2+ and Pd0 are also present on the surfaces of the CAC and WAC catalysts but only Pd2+ is present on the surface of the SAC catalysts, which results in better catalytic activity for SAC than that of the CAC and WAC catalysts. When the ternary composite filter was prepared by inserting the catalyst between the cigarette filter and the acetate filter rod, the smoking tests showed that the amount of CO in the main cigarette smoke decreased noticeably. The SAC catalyst reduced CO by 25.4% when the amount of Pd in the catalyst increased to 3.4% (w).
