Introduction
High value products from pyrolysis of biomass
• Traditional bubbling fluidized bed reactor:
– Liquid is mixture of many products
– Better selectivity is required for high value products
→ Use a batch Mechanically Fluidized Reactor (MFR)

Batch Mechanically Fluidized Reactor
• No need for:
– Inert fluidization medium (e.g. sand)
– Fluidization gas
• Can be used for batch pyrolysis:
– Liquid cuts can be collected for different temperature ranges
