## Key points

- Demand for materials like charcoal and activated carbon has led to exploitation of agro-industrial residues, including cherry stones
- Study describes methods used to prepare charcoal from cherry stones by subjecting them to final heating temperature of 600°C with or without an equal flow of nitrogen or air
- Isothermal time was set at 2 hours, providing adequate time to study carbonisation while varying the atmosphere
- Resulting charcoal had suitable characteristics as precursors of activated carbon; third sample prepared in different atmospheres was an activated carbon
- Yield in material carbonaceous was somewhat lower when applying nitrogen current and approximately 5% less when using air
- Authors studied how atmosphere during heat treatment affects CS in terms of yield, chemical composition, structure and pore structure
- Work highlights how agro-industrial residues can be utilized to produce valuable materials while also providing environmental benefits.

## Summary

The demand for materials such as charcoal and activated carbon has led to the exploitation of agro-industrial residues, including cherry stones. In this study, the authors describe the methods used to prepare charcoal from cherry stones (CS) by subjecting them to a final heating temperature of 600 {\deg}C with or without an equal flow of nitrogen or air. The isothermal time was set at 2 hours, providing adequate time to study carbonisation while varying the atmosphere. The resulting charcoal had suitable characteristics as precursors of activated carbon; of the three samples prepared in different atmospheres (*N, N~ and AN), the third was an activated carbon. The yield in material carbonaceous was somewhat lower when applying the nitrogen current and approximately 5% less when using air. Additionally, the authors studied how atmosphere during heat treatment affects CS in terms of yield, chemical composition, structure and pore structure. This work highlights how agro-industrial residues can be utilized to produce valuable materials while also providing environmental benefits.
