In this study, we prepared two catalysts for selective hydrogenation of acetylene, Pd/SiO2 catalyst and modified Pd/SiO2. We try to clarify coke composition and the effect of coke on the catalyst performance between the Pd/SiO2 catalyst and modified Pd/SiO2 catalyst. Deactivation reaction test, TGA, and TPO experiments confirmed that the deactivation behavior of Pd/SiO2 in acetylene hydrogenation is improved when the catalyst is modified with promoter. The modification reduces the amount of green oil produced on the catalyst and makes green oil more volatile such that it is removed at relatively low temperatures. |
