This work aims to transform coffee silverskin (CSS), the only waste from the coffee roasting process, that worldwide amounts to about 76 million kg/yr, into value-added products within an integrated slow pyrolysis process. The study, performed at 280°C, 400°C and 500°C, determined the potential applications of the resulting fractions. Biochar has been studied as an adsorbent of organic pollutants in water, using methylene blue (MB) and methyl orange (MO), which are resp. cationic and anionic aromatic dyes, as model compounds, and with 400°C biochar giving the highest removal values, at 98% with MB and 40% with MO. Moreover, CSS biochar could be used to obtain renewable energy from its combustion, with 22.6-24.2 MJ/kg calorific values. The liquid fraction could be a potential source of caffeine, among phenolics, with 400°C aqueous phase presenting the highest concentration of caffeine (14.3 g/L). Concerning the gas fraction, it could be used to obtain heat for biomass drying before pyrolysis. Hence, use of the pyrolysis products as described would allow zero-waste to be achieved in the coffee roasting industry, thus promoting the green and circular economy and production of green chems. and materials in a biorefinery context. The experimental part of the paper was very detailed, including the reaction process of Triacetonamine(cas: 826-36-8Synthetic Route of C9H17NO)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Synthetic Route of C9H17NO
