Feasibility of Biochar Preparation with Solar Pyrolysis Method

China is a large agricultural country with annual output of straw resources. Compared other treatment technologies, pyrolysis technology has the advantages simple operation and high utilization value products, but traditional takes combustion fossil fuels as heat source, which problem energy consumption. Solar attracted much attention because its cleanliness sustainability. To explore feasibility solar straw. In this paper, corncob biochar prepared by device (muffle furnace tube furnace) were compared. The experimental results show that can reach temperature range biomass, yield physicochemical properties obtained are similar to those device. Therefore, preparation feasible method.
