Utilization of high-quality biomass resources such as Miscanthus is considered an effective way to alleviate energy shortages and develop a low-carbon energy economy. In this work, the economic benefits and environmental impacts of producing hydrocarbon biofuel by fast pyrolysis and catalytic hydrotreatment from Miscanthus were investigated, along with the differences in the utilization of biochar: combustion for heat supply (HS), soil amendment (SA) and upgrading to activated carbon (AC). The hydrocarbon biofuel mass yields of up to 23.3 % for all scenarios. The SA scenario had the lowest sel...
