摘要

Abstract

The purpose of this study is to increase acrolein yield and capability of coking resistance in the reaction of glycerol dehydration to acrolein by assembling metal phosphate supported on HZSM-5 catalyst. The as-prepared catalysts were characterized by XRD

SEM

EDS

BET

-TPD

-TPD and Py-IR techniques. It was found that metal phosphate species were incorporated into the porous structure of HZSM-5 zeolites

thus influencing the surface and textural physico-chemical properties of the supporters. The alkaline-treated HZSM-5 catalyst promoted the dispersion of phosphate species on the carriers. Moreover

the amount of strong acidity was tremendously improved by adding the different metal hydrophosphates and the catalysts show high catalytic activity. In this present work

the Sn

1/4

/HZSM-5 catalyst exhibited good performance in the catalytic activity and coking resistant ability

which resulted in a high acrolein yield of 83% initially and acrolein yield of 68% after 30 h. The acidity

especially the ratio of strong to weak acid

plays an important role in promoting acrolein yield and stability simultaneously.
