Abstract
The invention concerns a zeolite with structure type MTT comprising MTT zeolite crystals with a size of less than 5 μm, at least a portion of the MTT zeolite crystals being in the form of MTT zeolite crystal aggregates, said zeolite being characterized in that the granulometry of the aggregates is such that the dimension Dv,90 is in the range 40 nm to 100 μm. The invention also concerns the preparation of the zeolite and the use of the zeolite as a catalyst in a process for converting hydrocarbon feeds, and in particular in a process for isomerizing straight chain paraffins.
