The effects of EFAl extraction on 2-methylpentane cracking over steamed HY
- Queen`s Univ., Kingston, Ontario (Canada); and others
The authors have examined the cracking of 2-methylpentane at 400{degrees}C on a steamed HY catalyst and on the same catalyst after extraction of its extra-framework aluminum (EFAl) using ammonium hexafluorosilicate. MAS-NMR data show that this procedure removes the EFAl, leaving the framework aluminum (FAl) intact. Kinetic runs on the various catalysts produced by steaming alone and by steaming followed by EFAl extraction have yielded quantitative reaction parameters, which are obtained by fitting the observed conversion and selectivity data with well-defined theoretical equations. 30 refs., 6 figs., 4 tabs.
