摘要

Abstract

A series of Ni-based catalysts were prepared

via

structural topological transformation from the Ni@Al

layered double hydroxides (LDHs) precursors

and applied for the deep catalytic hydrogenation saturation of pyrene in a high-pressure reactor. The pore structures

active species dispersion

surface morphology

amount and type of acid of the prepared catalysts were characterized by BET

XRD

SEM

TEM

XPS

SEM

-TPD and Py-IR. We studied the influence of physicochemical properties of Ni-based catalysts on the regularity and mechanism of deep hydrogenation of pyrene. Meanwhile

the synergy between Ni and Mo

and the interaction between active metals and support were discussed to further reveal the constitutive relationship during the hydrogenation reaction of pyrene. The results of the evaluation of the catalytic hydrogenation of pyrene show that the as-prepared NiMo mixed metal oxide (MMO) catalyst showed excellent catalytic activity: ~95% pyrene conversion

90.12% for the selectivity of deep hydrogenation products (hexahydropyrene

decahydropyrene and hexadecahydropyrene). It was expected that the successfully preparation and utilization of NiMo-MMO catalyst could provide a theoretical basis for the design of this kind of catalysts for deep catalytic hydrogenation of polycyclic aromatic hydrocarbons (PAHs).
