چکیده
|
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.
