In order to investigate the amount of carbon formed on the surface ofγ-Al2O3,the samples were subjected to CAT-CS analysis,with the results listed in Table 1.The results showed that the carbon content of 1-MN/Al was 0.90%,which indicated that after impregnation and toluene extraction,only a small part of 1-MN was chemisorbed on the surface ofγ-Al2O3.When the carbon content of 1-MN/Al-AC was higher and reached3.31%,it could indicate that after the accelerated coking process,a large part of coke species existed on the surface ofγ-Al2O3.
