AB  - In this study, carbonization products of grape pomace (hydrochar and process water) have been thoroughly characterized in order to assess its fuel properties, physico-chemical composition and to optimize its production. The obtained detailed insight into transformations of the biomass during hydrothermal conversion between 180-220 degrees C revealed that the hydrochar obtained at 220 degrees C exhibits a considerable energetic potential, increased porosity and re-adsorption abbility. Hydrothermally induced structural changes in the obtained hydrochars were unveiled by thermal and morphology analysis, FTIR and NIR spectroscopy. Temperature increment caused a decrease in antioxidative capacity, anthocyanin and organic acid content in process water and simultaneous increase in total phenolic and individual organic components content. The overall effect of the reaction temperature on products characteristics was assessed by multivariate data analysis. Obtained results substantiated the suitability of hydrothermal conversion of grape pomace into highly valuable fuels and versatile products.

AB  - Hydrochar produced via hydrothermal carbonization of grape pomace was considered as novel sorbent of Pb2+ from aqueous solution. In order to enhance the adsorption capacity, hydrochar was chemically modified using 2 M KOH solution. Both materials were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction technique. Batch experiments were performed to examine the effect of sorbent dosage, pH and contact time. Obtained results showed that the KOH treatment increased the sorption capacity of hydrochar from 27.8 mg g(-1) up to 137 mg g(-1) at pH 5. Adsorption of lead 'on either of the materials was achieved through ion-exchange mechanism, chemisorption and Pb2+-Tr interaction. The Sips isotherm model gave the best fit with the experimental data obtained for Pb2+ sorption using activated hydrochar. The adsorption kinetic followed a pseudo second-order model. Thermodynamic parameters implied that the Pb2+ binding for hydrochar surface was spontaneous and exothermic process. Findings from this work suggest that the hydrothermal carbonization is a promising route for production of efficient Pb2+ sorbents for wastewater treatment.
