摘要：
(Figure Presented) Com-paring mechanisms: The so-called hydrocarbon pool mechanism does not operate with zeolite ZSM-22 in the methanol-to-olefin (MTO) conversion process as a result of the narrow channels (0.57 nm) in its framework structure. However, this provided a condition free of secondary reactions for detailed mechanistic studies, with H/D exchange patterns of toluene suggesting a paring mechanism. © 2006 Wiley-VCH Verlag GmbH & Co.
