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.
Claims6
A process for catalytic isomerisation of alkyl aromatic hydrocarbons in a hydrocarbon process stream comprising:
- contacting the alkyl aromatic compound-containing hydrocarbon stream under catalytic 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 cc/g;
- and
- effecting isomerisation of the alkyl aromatic hydrocarbons.
