Pyrolysis processes of the shell of the Juglans regia L. in the temperature range of 250-550°C to produce charcoal

The article presents the results of scientific research on the processing of nut shells by pyrolysis. The physical and chemical properties of walnut shells and decomposition products obtained by pyrolysis of walnut shells in different temperature regimes are described. The process of pyrolysis of walnut shells in the temperature range of 250-550°C with the formation of charcoal without air access was studied. It is established that the output of charcoal from the shell of Greek nuts is at 550°C 31.3% weight.
