Catalyst comprising a 10MR zeolite and a 12MR zeolite and its use in the transalkylation of alkylaromatic hydrocarbons

摘要

Catalyst (I) comprises a zeolite having channels with opening defined by a ring with 10 oxygen atoms (10 MR), a zeolite having channels or lateral pockets with opening defined by a ring with 12 oxygen atoms (12 MR), a metal (group IIIA and VIIB metals) and a porous mineral matrix (where the catalyst is deprived of group VIII metal).
