Zeolite ERS-10 has been characterised as acid catalyst for ethylbenzene(EB) disproportionation and benzene alkylation. In the disproportionation of EB, ERS-10 shows some similarity with ZSM-12. In the alkylation of benzene with propylene a peculiar behaviour is related to the by-production of diisopropylbenzenes (DIPBs). Like ZSM-5 and ZSM-12, the preferred isomer produced by ERS-10 is the para. A Spaciousness Index (SI) = 5.3 and the preferred formation of p-DIPB seem to indicate that the effective pore-width of ERS-10 is in the intermediate range between large and medium pore zeolites.
