Effects of Active Metal Modification on C9 Petroleum Resin Hydrogention Activity of Pd/γ-Al2O3 Catalysts
Pages: 15-19,8
Year: Issue:  12
Journal: Zhejiang Chemical Industry

Abstract: 选择γ-Al2O3负载钯催化剂为研究对象,通过添加、活性金属考察对催化剂C9石油树脂催化加氢活性及稳定性等的影响,利用N2-物理吸附、XRD、SEM、TEM、NH,一TPD等实验手段对改性后的催化剂进行了表征。研究结果表明,Pd/γ-Al2O3催化剂在c,石油树脂的催化加氢反应中的稳定性与积炭及硫中毒密切相关。以碱土金属Mg对γ-Al2O3改性后形成的MgAl2O4有助于降低γ-Al2O3载体的酸...
