Abstract
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 ratio than Hβ, HUSY and ZSM-5. The improvement in catalytic performance of SAPO-11 is mainly attributed to the specific pore structure, weak acid strength and low acid amount on SAPO-11.
