Porosity of CHA Zeolite Driving the Formation of Polyaromatic Coke Species in the Methanol to Olefins Reaction

The pore size of the chabazite structure is exceptionally suitable for methanol to olefins (MTO) reaction. reaction has an induction period required formation a hydrocarbon pool (HP), usually composed aromatic compounds different sizes. HP alkylated by and afterward cracked, leading olefins. Despite importance HP, its growth in are exceedingly dependent on porosity catalyst. ideal that formed remains stable throughout because causes blockage small catalyst pores, decreasing capacity. Herein we studied zeolites with structure, caused variation particle pores’ volume. Porosity influenced species quantity (as revealed thermogravimetric analysis (TGA)) polymerization degree (gas chromatography coupled mass spectrometer (GC-MS) analysis) and, consequently, MTO reaction’s performance.
