The addition of V/sub 2/O/sub 5/ is known to increase the selectivity of formation of p-xylene (PX) from 1-octene in the presence of the Na form of superhigh-silica zeolite (SHSZ). The preferential formation of PX from ethylene, propene, and 1-hexene in the presence of SHSZ of the ZSM type with added Sb/sub 2/O/sub 3/, MgO, and B/sub 2/O/sub 3/ has been reported in patents. Continuing our study of the catalytic properties of SHSZ, we have examined the effects of adding V/sub 2/O/sub 5/ on the conversions of C/sub 3/-C/sub 4/ olefins. For purposes of comparison, experiments using ethylene with the original and modified catalysts were carried out, since the reactions of ethylene over catalysts of this type have been thoroughly studied.
