Hot-Water Extraction (HWE) Method as Applied to Lignocellulosic Materials from Hemp Stalk

The article describes the process of hot water extraction treatment a specific material—in this case, shavings hemp shives different thicknesses, sorted by their thickness into three fractions 0–4 mm, 4–8 and 8–12 mm. In addition, each sample from given fraction was separately subjected to one, two, processes. After material treated with extraction, cellulose determination performed using Kürschner–Hoffer method in order find out effect that had on content test material. This research aims determine whether strongly alters content, which may translate change efficiency when producing second-generation biofuel produced showed smallest losses were chips mm thick, while largest thick. Each repetition resulted loss cellulose, steepest occurring after second HWE, third repetition—the exception being fraction, decrease occurred first HWE (Hot Water Extraction) process.
