Fig. 2. Biochar catalyst loading impacts mass yields and py-gas composition at 800 C. The effect of biochar catalyst loadings on the product yields (a), and the effect on the py-gas composition (b). 0B denotes without catalyst or sand at 500 C downstream; 0S denotes with sand in place of catalyst. 0.2, 0.33, and 1 denote catalyst to feedstock mass ratios. The py-gas composition was calculated on an inert-carrier-gas-free basis. Error bars represent one standard deviation of triplicate experiments; some error bars are small and not visible.
