Abstract

Abstract: 129Xe was used as probe to detect the exact position of coke that caused the deactivation of the Mo/Hβ-Al2O3 catalyst. The carbon deposition was located at the positions of the channel intersections in Hβ zeolite.

Key words: olefin metathesis, molybdenum, alumina, Hβ zeolite, propene, solid-state nuclear magnetic resonance, 129Xe
