摘要

Abstract

The selective catalytic hydrogenation of naphthalene to high-value tetralin was systematically investigated. A series of Al

catalysts containing different active metals (Co

W) were prepared by incipient wetness impregnation. The effects of different active metals forms (oxidation

reduction

sulfuration) and reaction conditions on naphthalene hydrogenation were investigated and the catalysts were characterized by XRD

XPS

BET

- TPD and SEM. Especially

Ni-Mo/Al

was first used in this reactive system. The results show that the oxidative 4%NiO-20%MoO

/Al

is the best catalyst for the preparation of tetralin. The conversion of naphthalene and the selectivity of tetralin can reach 95.62% and 99.75% respectively at 200 ℃

8 h and 6 MPa. Compared with reduced and sulfureted 4%NiO-20%MoO

/Al

catalysts

oxidative 4%NiO-20%MoO

/Al

has a well dispersed and uniform monolayer of the active metals

larger pore volume and size

and larger total acidity. NiO-MoO

/Al

has a synergistic effect between NiO activity and MoO

selectivity.
