(author), Kapteijn, F. (author)A systematic study of the effect of physicochemical properties affecting catalyst deactivation, overall olefin selectivity and ethylene/propylene ratio during the methanol-to-olefins (MTO) reaction is presented for two zeolites with the DDR topology, namely Sigma-1 and ZSM-58. Both catalysts show high selectivity towards light olefins and...journal article 2016

Seoane, B. (author), Dikhtiarenko, A. (author), Mayoral, A. (author), Tellez, C. (author), Coronas, J. (author), Kapteijn, F. (author), Gascon, J. (author)The effect of synthesis pH and H2O/EtOH molar ratio on the textural properties of different aluminium trimesate metal organic frameworks (MOFs) prepared in the presence of the well-known cationic surfactant cetyltrimethylammonium bromide (CTAB) at 120 °C was studied with the purpose of obtaining a MOF with hierarchical pore structure. Depending...journal article 2015

Serra-Crespo, P. (author), Dikhtiarenko, A. (author), Stavitski, E. (author), Juan-Alcañiz, J. (author), Kapteijn, F. (author), Coudert, F.X. (author), Gascon, J. (author)We report a series of powder X-ray diffraction experiments performed on the soft porous crystals MIL-53(Al) and NH2-MIL-53(Al) in a diamond anvil cell under different pressurization media. Systematic refinements of the obtained powder patterns demonstrate that these materials expand along a specific direction while undergoing total volume...journal article 2014
