Guanghua’s research is focused on probing the deactivation process in zeolite catalysts by using the discrete modelling approach and then optimizing distributions of active sites and pores to achieve more stable and active catalysts. The discrete approach is advantageous in identifying ‘available’ active sites because the percolation theory can be well coupled in this approach. The proposed discrete model would cover the length scales from zeolite crystal to industrial catalyst pellet and include the detailed geometry and topology of the pore system. Benzene alkylation with propene into cumene is taken as the reaction system due to its both industrial importance and academical significance. Propene oligomerization and products accumulation in zeolite ‘cages’ are the probable causes resulting in the deactivation. Therefore, it is interesting to evaluate the importance level of the two causes of deactivation. Moreover, optimized hierarchical pore network is planned to be introduced into zeolite catalysts so that more active sites would be close to or on the surfaces of macropore or mesopore, which is believed to increase both catalyst stability and activity. Experiments (e.g., TG) are planned to validate the proposed models. Lastly, attempts will be made to develop the optimized zeolite catalyst.
