The relationships between conversion efficiency, operating parameters and influential factors, such as treatment temperatures, catalyst sizes and space velocities have been examined. Also, the related kinetic model is proposed to describe the reaction mechanism. The experimental results indicate that the catalyst used accelerates the reaction rate of decomposition of naphthalene, and decreases the reaction temperature. A high conversion (over 95 %) can be achieved at the moderate reaction temperature of 480 K and space velocity below 35000 hr-1. In addition, the reaction temperature is a determining factor in the catalytic decomposition. The results indicate that Rideal-Eley mechanism and Arrhenius equation can be reasonably applied to describe the data by using the pseudo-fist-order reaction kinetic equation. The activation energy (17.8 kcal/mol) andfrequency factor (3.26 × 1017 s -1) were obtained therefore.application/pdf231533 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所多環芳香族烴萘觸媒焚化反應動力 模式polycylic aromatic hydrocarbonscatalytic incinerationnaphthalenekinetic model.[SDGs]SDG11reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22138/1/922211E002056.pdf
