- •
Gradual formation of methylated benzene species during the initial stages of the chloromethane to olefins reaction is confirmed using ex situ13C NMR and in situ FTIR.
- •
Direct correlation between chloromethane conversion and concentration of methylated aromatics during induction period.
- •
Extrapolation of methanol-to-olefins hydrocarbon pool mechanism to the chloromethane-to-olefins (CTO) reaction.
- •
Loss of micropore volume by carbon-filling suggests that the deactivation of SAPO-34 during the CTO reaction proceeds through the growth of polyaromatics.
