ZEOLITE MTT CONTAINING CRYSTAL AND CRYSTAL AGGREGATE HAVING SPECIFIC PARTICLE SIZE AND ITS USE AS STRAIGHT-CHAIN PARAFFIN ISOMERIZATION CATALYST

摘要

PROBLEM TO BE SOLVED: To obtain an MTT structure type zeolite which is obtained by combining at least one binder with at least one metal selected from elements of the group VIII of the periodic table, is used as a catalyst and has improved catalytic performances in conversion of a hydrocarbon in terms of activity and selectivity, for example, in the isomerization of a light paraffin-based hydrocarbon containing 5-10 carbon atoms per one molecule. SOLUTION: This MTT structure type zeolite contains a zeolite MTT crystal having <5μm size. At least a part of the zeolite MTT crystal has an aggregate form of zeolite MTT. The aggregate has a particle size of 40 nm to 100μm Dv. 90 value.
