Pyrolysis Characteristics of Jatropha Seed Shell Waste in a Fluidized Bed Reactor

The effects of reaction temperature, particle size and gas flow rate on the products distribution from pyrolysis of Jatropha seed shell waste were determined in a fluidized bed reactor. With increasing temperature, char yield decreases down to 30 wt% while gas yield increases up to 41 wt%. The maximum bio-oil yield is 42 wt% at 500 degrees C with particle size of 2.0 mm and gas flow rate above 3 U-mf. The bio-oil yield decreases about 7-9% at lower gas flow rate with larger particle size.
