Abstract
A process for catalytic isomerisation of alkyl aromatic compounds in a hydrocarbon process stream comprising contacting the alkyl aromatic compound-containing hydrocarbon stream under isomerisation conditions with a crystalline zeolite catalyst consisting of individual, primary crystals having an intracrystalline, non-crystallographic mesopore system and a mesopore volume of the zeolite crystals above 0.25.
