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.
