Abstract

The pyrolysis of the walnut shell was carried out in a lab-scale continuous fluidized bed reactor at a temperature range of 400 to 600 °C. Thermogravimetric analysis technique was used to determine the thermal properties of the walnut shell. The bio-char product obtained from pyrolysis was analyzed to evaluate the effect of the pyrolysis temperature. Increasing the pyrolysis temperature to 600 °C improved the High Heating Value (HHV) and % C value of the bio-char product. These results showed that the optimum temperature value for bio-char production from walnut shell was 600 °C.
