Removal and determination of carbon monoxide based on copper oxide immobilized on Zeolite ۱۳X Nanocatalys t by catalytic oxidation process and gas flow analyzer

Carbon monoxide is one of the main air pollutants, mainly produced from the incomplete combustion of fossil fuels.  dis study aims to oxidize carbon monoxide by copper oxide nanoparticles immobilized on zeolite۱۳X substrate. The present investigation was conducted to determine the TEMPeffect of carbon monoxide concentration parameters (in the range of ۲۰۰-۱۴۰۰ ppm) and reaction temperature (in the range of ۱۰۰-۵۰۰ °C) on the efficiency of carbon monoxide conversion by CuO/Zeolite ۱۳X nanocatalyst. The design of the experiment and the determination of the number of experiments were analyzed using the central composite design method, and the statistical test of analysis of variance was done using the response surface method. Also, the structural and morphological characteristics of the nanocatalyst were investigated using BET, BJH, FE-SEM, EDX, and XRF tests. The results show dat CuO/Zeolite ۱۳X nanocatalyst efficiently oxidizes carbon monoxide. The highest conversion efficiency of ۸۲.۶% was obtained at a temperature of ۴۰۰ °C and a carbon monoxide concentration of ۵۰۰ ppm as the optimal conditions. According to the EDX test results, copper oxide nanoparticles with a weight percentage of ۵.۹% were loaded on the Zeolite ۱۳X substrate. Design Expert۱۱ software reduced the cubic model with an R۲ coefficient of ۰.۹۸.
