双金属气凝胶催化剂协同臭氧催化氧化甲苯的性能研究
Study on performance of bimetallic aerogel catalyst cooperating with ozone for catalytic oxidation of toluene
Mn-Fe,Mn-Cu,Mn-Ce and Mn-Co bimetallic aerogel catalysts are prepared via sol-gel method,and used to cooperate with ozone to catalyze oxidation of toluene.Mn-Co bimetallic aerogel catalyst is found to have the optimal catalytic activity among the four catalysts.Furthermore,the influences of manganese-cobalt ratio,manganese-cobalt loading amount,concentration ratio of toluene to ozone,and reaction temperature on the catalytic effect are studied.The results show that this catalyst exhibits excellent and stable toluene degradation in the activity test under the conditions that the ratio of Mn to Co is 1∶0.5,the total loading amount of Mn and Co is 5%,the ratio of toluene to ozone is 1∶11,temperature is 75oC,and continuous operation lasts for 10.This catalyst provides a new efficient application scheme for the synergistic ozone catalytic oxidation of toluene.
