Maceration of Waste Cork in Binary Hydrophilic Solvents for the Production of F...
Şen, Umut; Viegas, Catarina; Duarte, Maria Paula; Maurício, Elisabete Muchagato; Nobre, Catarina; Correia, Ricardo; Pereira, HelenaPublisher Copyright: © 2023 by the authors.; Waste-grade cork samples of Quercus cerris were subjected to maceration extraction using 7 different solvents, including pure water (I), pure acetone (II), 75% aqueous ethanol (III), 75% aqueous methanol (IV), 75% aqueous acetone (V), 50% aqueous acetone (VI), and 25% aqueous acetone (VII). The extract yields, extract compositions, as well as antioxidant and antimicr...
Effect of Bark Biochars on Properties of Steam-Activated Carbons
Şen, Umut; Nobre, Catarina; Martins, Marta; Gonçalves, Margarida; Pereira, HelenaPublisher Copyright: © 2023 by the authors.; Bark is a heterogeneous solid material comprising mainly of phloem and cork fractions. These fractions differ in chemical composition and anatomical structure, and value-added activated carbons produced from these fractions have different surface properties. Low-temperature pyrolysis was shown to be a promising method for producing activated carbon precursors from ba...
