| Abstract: | After the oxidation mother liquor recovery system of Luoyang PTA plant put into operation,the imported Pd/C catalyst activity was decreased.The causes for the catalyst deactivation were analysed and discussed.By catalyst bed tilting treatment,using deionized water to clean,normal use of Pd/C catalyst was ensured. |
