Journal ArticleDOI
Structure–performance descriptors and the role of Lewis acidity in the methanol-to-propylene process
Irina Yarulina,Irina Yarulina,Kristof De Wispelaere,Simon Bailleul,Joris Goetze,Mike Radersma,Edy Abou-Hamad,Ina Vollmer,Maarten G. Goesten,Brahim Mezari,Emiel J. M. Hensen,Juan S. Martinez-Espin,Magnus Mortén,Sharon Mitchell,Javier Pérez-Ramírez,Unni Olsbye,Bert M. Weckhuysen,Veronique Van Speybroeck,Freek Kapteijn,Jorge Gascon,Jorge Gascon +20 more
TL;DR: It has been shown that introducing Lewis acidity into Brønsted acidic zeolites boosts their performance, and although BrøNsted acidity is found to define propylene selectivity, Lewis acidality is responsible for prolonging lifetime.
Journal ArticleDOI
New insights into catalyst deactivation and product distribution of zeolites in the methanol-to-hydrocarbons (MTH) reaction with methanol and dimethyl ether feeds
Juan S. Martinez-Espin,Magnus Mortén,Ton V. W. Janssens,Stian Svelle,Pablo Beato,Unni Olsbye +5 more
TL;DR: In this article, MeOH and dimethyl ether were compared as feedstock for the methanol-to-hydrocarbons (MTH) reaction over H-ZSM-5 (MFI), H-SSZ-24 (AFI), and H-SAPO-5(AFI) catalysts at 350 and 450 °C.
Journal ArticleDOI
Hydrogen transfer versus methylation: on the genesis of aromatics formation in the Methanol-To-Hydrocarbons reaction over H-ZSM-5
Juan S. Martinez-Espin,Kristof De Wispelaere,Ton V. W. Janssens,Stian Svelle,Karl Petter Lillerud,Pablo Beato,Veronique Van Speybroeck,Unni Olsbye +7 more
TL;DR: In this article, the authors present the reaction of isobutene with methanol and DME as an efficient tool for measuring the relative formation rates of alkenes and arenes, and provide detailed mechanistic insight into the hydrogen transfer reaction.
Journal ArticleDOI
Benzene co-reaction with methanol and dimethyl ether over zeolite and zeotype catalysts: Evidence of parallel reaction paths to toluene and diphenylmethane
Juan S. Martinez-Espin,Kristof De Wispelaere,Marius Westgård Erichsen,Stian Svelle,Ton V. W. Janssens,Veronique Van Speybroeck,Pablo Beato,Unni Olsbye +7 more
TL;DR: In this article, the reactivity of methanol and dimethyl ether toward benzene was studied over zeolitic materials with different topology and acid strength (H-ZSM-5, H-SSZ-24, and H-SAPO-5).
Journal ArticleDOI
Dampened circumrotation by CH···π interactions in hydrogen bonded [2]rotaxanes.
Jose Berna,Mateo Alajarin,Juan S. Martinez-Espin,Lilian Buriol,Lilian Buriol,Marcos A. P. Martins,Raul-Angel Orenes +6 more
TL;DR: Establishment of CH···π interactions between the aliphatic axis and the benzylic amide macrocycle of hydrogen-bonded [2]rotaxanes causes a measurable interference in the pirouetting submolecular motion of these interlocked molecules.
