Following calcination, carburization and passivation, the Mg-Mo2C/HY and K-Mo2C/HY catalysts had significantly reduced surface area, total pore volume,micropore area andmicropore volume (Table 1)comparedtothe Mo2C/HY catalyst. However, the surface area was not strongly dependent upon the amount of Mg added, with all the Mg-Mo2C/HY catalysts having surface areas in the range 389¨C462 m2/g, compared to 522 m2/g for the Mo2C/HY. The relative loss in BET and micropore area with Mg or K addition to the Mo2C/HY, was almost the same. Fig. 1 shows themicropore size distribution of the 2%Mg-Mo2C/HY catalyst compared to the HY zeolite. [ Last edited by ankang276 on 2011-8-9 at 13:18 ] |
