Journal ArticleDOI
Unraveling the reaction mechanisms governing methanol-to-olefins catalysis by theory and experiment
Karen Hemelsoet,Jeroen Van der Mynsbrugge,Kristof De Wispelaere,Michel Waroquier,Veronique Van Speybroeck +4 more
TL;DR: An overview of proposed reaction mechanisms for the MTO process is given, focusing on the archetypal MTO catalysts, H-ZSM-5 and H-SAPO-34, and reaction mechanisms proposed thus far involve aromatic or aliphatic intermediates.
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
First principle chemical kinetics in zeolites: the methanol-to-olefin process as a case study
Veronique Van Speybroeck,Kristof De Wispelaere,Jeroen Van der Mynsbrugge,Matthias Vandichel,Karen Hemelsoet,Michel Waroquier +5 more
TL;DR: It is shown that present computational techniques have matured to a level where accurate enthalpy barriers and rate constants can be predicted for reactions occurring at a single active site and comparison with experimental data such as apparent kinetic data for well-defined elementary reactions has become feasible.
Journal ArticleDOI
Effect of zeolite topology and reactor configuration on the direct conversion of CO2 to light olefins and aromatics
Adrian Ramirez,Abhishek Dutta Chowdhury,Abhay Dokania,Pieter Cnudde,Mustafa Caglayan,Irina Yarulina,Edy Abou-Hamad,Lieven Gevers,Samy Ould-Chikh,Kristof De Wispelaere,Veronique Van Speybroeck,Jorge Gascon +11 more
TL;DR: The direct transformation of CO2 into high-value-added hydrocarbons (i.e., olefins and aromatics) has the potential to make a decisive impact in our society.
Journal ArticleDOI
Insight into the Effect of Water on the Methanol-to-Olefins Conversion in H-SAPO-34 from Molecular Simulations and in Situ Microspectroscopy
Kristof De Wispelaere,Kristof De Wispelaere,Caterina S. Wondergem,Bernd Ensing,Karen Hemelsoet,Evert Jan Meijer,Bert M. Weckhuysen,Veronique Van Speybroeck,Javier Ruiz-Martínez +8 more
TL;DR: The role of water in the methanol-to-olefins (MTO) process over H-SAPO-34 has been elucidated by a combined theoretical and experimental approach, encompassing advanced molecular dynamics simulations and in situ microspectroscopy.
