Beschreibung
Zusammenfassung:	An improved process is provided for catalytic pyrolysis of biomass, comprising pneumatically injecting a biomass feed via a pneumatic injection line into a fluidized heat medium, for example, hot catalyst, with a carrier gas at a velocity of from 5 to 40 m/s in at least one mixing zone in communication with a pyrolysis reactor in which catalytic pyrolysis occurs, and maintaining a catalyst/biomass mixture flowrate ratio (C/B) of from 4 to 40 downstream from the point of catalyst injection via a catalyst injection line in the at least one mixing zone.
