Influence of hierarchical ZSM-5 catalysts with various acidity on the dehydration of glycerol to acrolein

Autor: Shufang Zhao, Songlin He, Kyung Du Kim, Lizhuo Wang, Ryong Ryoo, Zichun Wang, Jun Huang

Publikováno v: Magnetic Resonance Letters, Vol 1, Iss 1, Pp 71-80 (2021)

The main challenge in the dehydration of glycerol to acrolein lies in overcoming catalyst deactivation and improving the selectivity to acrolein. The relationship between the acidity in the mesoporous channels and catalytic performance of glycerol de
