Abstract

Coke formation upon methanol and ethylene reaction over two well-characterized industrial H-ZSM-5-based catalysts was studied mainly by UV-visible spectroscopy. The investigations were complemented by TGA/GC determination of the H/C ratio of the carbonaceous deposits as well as by in-situ IR and conversion measurements. Various stages of coke formation as a function of reaction temperature, catalyst acidity and morphology were distinguished and correlated to catalytic performance.
