Effect of mesoporosity against the deactivation of MFI zeolite catalyst during the methanol-to-hydrocarbon conversion process
TL;DR: In this paper, the effects of mesoporosity on catalyst longevity of methanol-to-hydrocarbon (MTH) reactions have been investigated using a number of MFI zeolites with different degrees of mesophorosity, which were obtained via the post-synthetic desilication, dry-gel conversion in nanocarbon templates, and hydrothermal synthesis with the addition of organosilane surfactants.

On the Reaction Mechanism for Hydrocarbon Formation from Methanol over SAPO-34 2. Isotopic Labeling Studies of the Co-reaction of Propene and Methanol
Ivar M. Dahl,Stein Kolboe +1 more
TL;DR: In this paper, 13C-Methanol and 12C ethene were co-reacted over SAPO-34 in a flow system at 400°C using argon as a carrier (diluent) gas.

Conversion of methanol into hydrocarbons over zeolite H-ZSM-5: ethene formation is mechanistically separated from the formation of higher alkenes.
Stian Svelle,Finn Joensen,Jesper Nerlov,Unni Olsbye,Karl Petter Lillerud,Stein Kolboe,Morten Bjørgen +6 more
TL;DR: It is stated that, for H-ZSM-5, ethene appears to be formed exclusively from the xylenes and trimethylbenzenes, an insight of utmost importance for understanding and possibly controlling the e thene/propene selectivity in methanol-to-alkenes catalysis.
