Abstract
The study focused on producing biochar from pistachio shells (Pistacia vera L.) and evaluating its potential applications, particularly its sorption properties and calorific value for energy use. Biochar was obtained through conventional pyrolysis at 300, 400, and 500°C with a heating rate of 10 °C·min–1 and a 1 hour residence time at the final temperature. One biochar series was modified with hydrogen peroxide to introduce additional oxygen—containing functional groups. Physicochemical analysis showed that, compared with the raw biomass, the biochars exhibited higher carbon and mineral content, as well as low ash content and a high calorific value, indicating potential for energy applications. H2O2—modified samples contained more oxygen. FTIR spectra confirmed characteristic functional groups such as O–H, C=C, C=O, and Si–O–Si in biomass and biochar, while functionalized biochars additionally displayed C–O and C–O–C bonds. Oxygen functional groups and aromatic structures influenced the adsorption of Cr(III) ions, although the adsorption capacities remained low and did not indicate promising sorption performance under the tested conditions. Increasing the pyrolysis temperature resulted in a higher degree of carbonization and improved calorific value. The highest value was obtained for P500 (31.681 MJ·kg–1), followed by P400 (29.319 MJ·kg–1) and P300 (27.307 MJ·kg–1).
