Understanding the Early Stages of the Methanol-to-Olefin Conversion on H-SAPO-34
Weili Dai,Chuanming Wang,Michael Dyballa,Guangjun Wu,Naijia Guan,Landong Li,Zaiku Xie,Michael Hunger +7 more
TL;DR: In this paper, the formation and evolution of carbenium ions during the early stages of the methanol-to-olefin (MTO) conversion on a H-SAPO-34 model catalyst were clarified via 1H MAS NMR and 13C MAS NMRI.
Journal ArticleDOI
A mechanistic basis for the effects of crystallite size on light olefin selectivity in methanol-to-hydrocarbons conversion on MFI
TL;DR: Light olefin selectivity in methanol-to-hydrocarbons conversion on MFI increases with an increase in crystallite size because intra-crystalline residence time of methylbenzenes increases as a consequence of increased transport restrictions as mentioned in this paper.

Conversion of methanol to hydrocarbons over zeolite H-ZSM-5 : On the origin of the olefinic species
Morten Bjørgen,Stian Svelle,Finn Joensen,Jesper Nerlov,Stein Kolboe,Francesca Bonino,Luisa Palumbo,Silvia Bordiga,Unni Olsbye +8 more
TL;DR: In this article, the reaction mechanism with respect to both catalyst deactivation and product formation in the conversion of methanol to hydrocarbons over zeolite H-ZSM-5 was examined.
Journal ArticleDOI
The mechanism of methanol to hydrocarbon catalysis.
TL;DR: Using other microporous catalysts that are selective for light olefins, methanol-to-olefin (MTO) catalysis may soon become central to the conversion of natural gas to polyolefins.

TL;DR: Zhang et al. (p. 1684) show that a hierarchical zeolite can be made through a simple process using a single structure-directing agent that causes repetitive branching, which leads to a material with improved transport and catalytic properties.

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.
