Abstract A Y-type molecular sieve and its preparation method is that said molecular sieve is treated under ammonia atmosphere and room temp. to 650 deg.C for 0.5-4 hr., optimize under 150-600 deg.c to treat 1-3 hr. to obtain the product. The invented Y-type molecular sieve is used in transalkylation of benzene and polyethylene benzene to prepare ethyl benzene, it possessed higher transalkylation activity and activity stability.
