摘要

Abstract

Shape-selective methylation of 2-methylnaphthalene (2-MN) was carried out over NH

F and Pt modified HZSM-5 (SiO

/Al

=83) catalysts in a fixed-bed down-flow reactor using methanol as methylating agent and 1

5-trimethylbenzene (1

5-TMB) as a solvent. Pt promoted HZSM-5 catalysts showed low concentration of coke-like polycondensed aromatics

F modification decreased non-shape-selective acid sites. After Pt and NH

F comodification

both conversion of 2-MN and selectivity tO2

6-DMN were improved. 6% NH

F/0.5% Pt/HZSM-5 catalyst exhibited 13.8% of 2-MN conversion with 6.2% of 2

6-DMN yield after 7 h time on stream (TOS)

and 2

6-/2

7-DMN ratio of 1.7 after 10 h of TOS.
