Influence of Pyrolytic Conditions on Pyrolytic Products of Walnut Shell

This paper took walnut shell as experiment material, under the conditions that the endpoint temperatures were 450°C, 600°C and 750°C respectively. And the average heating rate was 150°C/h, the pyrolytic products of walnut shell indicated that, under a certain condition, with the increase of pyrolysis temperature, the walnut shell charcoal yield rate showed a downward trend; While the yield rate of vinegar was increased, the average yield rate of charcoal and vinegar were 30.28% and 45.61% respectively.
