Zeolite catalyzed alkylation of toluene by alcohol
Vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using N2 carrier over a series of surface modified andunmodified ZSM-5 (Si/Al= 60-170) loaded with H3PO4, differing in the external surface treatment of the zeolites.The feed molar ratios of toluene/methanol and toluene/2-propanol were...
متن کاملMethylation of Naphthalene with Methanol over SAPO-11 Zeolite
Shape-selective methylation of naphthalene (NAPH) over SAPO-11 zeolite was carried out in a fixed-bed flow reactor under atmospheric pressure. Some zeolites, such as H-beta (Hβ), HUSY and ZSM-5 were also evaluated for comparison with SAPO-11 zeolite.The results showed that SAPO-11 exhibited higher stability, higher selectivity of 2,6-dimethylnaphthalene (2,6-DMN), and higher 2,6-/2,7-DMN r...

متن کاملXAFS Study on Re/Zeolite Catalysts for Direct Phenol Synthesis from Benzene with Molecular Oxygen
Introduction Phenol is an important chemical in industry but has been produced from benzene by the three-steps of cumene process. Direct phenol synthesis from benzene is one of the important subjects. However, no selective catalyst with good performance in an economically and environmentally favourable benzene-O2 system has been discovered to date. We have found Re/HZSM-5 promoted the direct ph...
