Effects of grain size and aggregation state of ZSM-5 on para-selectivity in alkylation of toluene with methanol
Source abstract
Abstract
The effect of nano-scale P2O5-ZSM-5 aggregates (NZA), dispersed nano-scale P2O5-ZSM-5 (DNZ), and micron-scale P2O5-ZSM-5 (MZ) on para-selectivity was investigated in detail. XRD, SEM, N2 physical absorption–desorption, NH3-TPD, Py-FT-IR, etc. were used to analyze the difference of nano-scale (~ 100 nm) and micron-scale ZSM-5. The results showed that, with the same amount of modifier, ZSM-5 aggregates showed the highest para-selectivity, followed by micron-scale ZSM-5, and dispersed nano-scale ZSM-5 (~ 100 nm). In addition, the nano-scale ZSM-5 also showed a better capacity to accommodate carbon deposition and higher activity.
