Abstract
Selective acetylene hydrogenation in ethylene is a significant technique to remove traces of acetylene for the ethylene industry. Finding an efficient supported Palladium (Pd) catalysts and applying Pd/Ceria (CeO2) is an important research area. The main purpose of this research was synthesizing Pd loading Ceria catalyst by incipient wetness impregnation method and characterizing surface features of the catalyst through H2-chemisorption and BET etc. Research data reveal Pd loading on the surface of Ceria as an outstanding catalyst for selective hydrogenation reactions when compared with Pd-modified gamma Alumina (γ-Alumina) with catalyst as the reference. Several catalysts differ from calcination temperature and various Pd loading prove calcination will improve the activity of the catalyst for hydrogenation reaction and Pd loading will impact the catalyst’s performance.
