Process optimization of a bench scale fast pyrolysis set-up has been performed in order to screen the performance and stability of modified MFI zeolites in the ex-situ upgrading of straw and wood derived pyrolysis vapors. Repeated regeneration of the parent zeolites was demonstrated at the bench scale unit. Harsh regeneration conditions led to temperature peaks and permanent loss in the zeolite`s acidity. A certain extent of mesopores is introduced to the parent zeolites by post-synthesis desilication to increase the zeolite`s active time on stream.
