Waterloo fast pyrolysis process

The experimental system used to carry out this work is a bench-scale installation based on Waterloo Fast Pyrolysis Process (WFPP) technology (19,20). The biomass feeder supplies a continuous biomass flow rate of between 5 and 100 g/h. Thermal decomposition of biomass occurs in a fluidized bed reactor with an inner section of 4.35 cm. ... 

During the last six years a fluidized bed fast pyrolysis process for biomass has been developed at the University of Waterloo (The Waterloo Fast Pyrolysis Process). This process gives yields of up to 70% of organic liquids from hardwoods or softwoods, which are the highest yet reported for a non-catalytic pyrolytic conversion process. A fluidized sand bed is used as a reactor and optimum liquid yields are normally obtained in the range of 450 to 550 C at about 0.5 seconds gas residence time with particles of about 1.5 mm diameter or smaller. Two units are in use, one with a throughput of 20 to 100 gms/hr, and another with a throughput of 1 to 4 kg/hr.
