Abstract

The isomerization of xylenes is effected in the presence of a silica-alumina catalyst and steam in an amount up to 1% by weight of hydrocarbon. The isomerization is effected at 300 DEG -500 DEG C., and atmospheric pressure. In the case of a fluidized or moving bed of catalyst steam is injected near the point of withdrawal of spent catalyst. The Provisional Specification refers to the addition of methyl alcohol instead of steam and to isomerization and disproportionation reactions.
