| Popis: | Understanding the deactivation process in porous catalysts is of tremendous economic significance. We demonstrate the feasibility of using the concentration polarization method to obtain the pore accessibility distribution at single particle level for the first time. By using this technique we could measure the pore blockage caused by Fe in fluid catalytic cracking particles as evidenced by correlating it to the activity. We expect this new single particle technique to increase our understanding of the deactivation processes occurring in porous catalysts. |
