Marrot, Laetitia published the artcileCharacterization of the compounds released in the gaseous waste stream during the slow pyrolysis of hemp (Cannabis sativa L.), Recommanded Product: 1,2-Dimethoxybenzene, the publication is Molecules (2022), 27(9), 2794, database is CAplus and MEDLINE.
This study aims to characterize and valorize hemp residual biomass by a slow pyrolysis process. The volatile byproducts of hemp carbonization were characterized by several methods (TGA, UV-VIS, TLC, Flash Prep-LC, UHPLC, QTOF-MS) to understand the pyrolysis reaction mechanisms and to identify the chem. products produced during the process. The obtained carbon yield was 29%, generating a gaseous stream composed of phenols and furans which was collected in four temperature ranges (F1 at 20-150°C, F2 at 150-250°C, F3 at 250-400°C and F4 at 400-1000°C). The obtained liquid fractions were separated into subfractions by flash chromatog. The total phenolic content (TPC) varied depending on the fraction but did not correlate with an increase in temperature or with a decrease in pH value. Compounds present in fractions F1, F3 and F4, being mainly phenolic mols. such as guaiacyl or syringyl derivatives issued from the lignin degradation, exhibit antioxidant capacity. The temperature of the pyrolysis process was pos. correlated with detectable phenolic content, which can be explained by the decomposition order of the hemp chem. constituents. A detailed understanding of the chem. composition of pyrolysis products of hemp residuals allows for an assessment of their potential valorization routes and the future economic potential of underutilized biomass.
