Catalytic pyrolysis of forest thinnings in a circulating fluidized bed reactor

摘要

1. VTT's 20 kg/h PDU operated smoothly with a spray-dried ZSM-5 catalyst 2. Catalytic pyrolysis in a CFB reactor is not as simple as just replacing the sand with a catalyst 3. Process conditions have to be chosen carefully to increase the effectiveness of the catalyst 4. Catalyst properties change in a five day experiment 5. Catalyst activity and lifetime are major issues.
