摘要

Abstract

Aromatization of methanol over co-impregnated La/Zn/HZSM-5 zeolite catalyst was studied.The selectivity of aromatics and BTX(benzene

toluene

and xylene)reached 64.0% and 56.6%

respectively

using La/Zn/HZSM-5 at 437℃

0.1 MPa and methanol WHSV(weight hourly space velocity)=0.8 h

-1

.Catalytic results showed that the La species was a very good promoter

increased selectivity of aromatics

and prolonged the catalyst lifetime on stream.The effects of the SiO

/Al

ratio in zeolite

Zn and La loading

WHSV

reaction temperature

water content in the feed and H

pretreatment of catalysts on the catalytic performance were studied in detail. Characterizations of the catalysts by thermogravimetric analysis(TGA)

-TPD(temperature programmed desorption)

SEM(scanning electron micrograph)

adsorption-desorption

XRD(X-ray diffraction) and XRF (X-ray fluorescence)

were carried out to understand the structure and discuss the aromatization performance of La/Zn/HZSM-5 zeolite catalyst.
