Influence of preparation conditions on the physical structure and surface properties of enteromorpha clathrate bio-char

Bio-char with rich pore structure was obtained by pyrolysis of enteromorpha clathrate (EC) and subsequent activation process. The effect methods, KOH concentrations used in heating rate studied. A new method that combined into one step proposed. bio-char via slow at 450°C 700°C had a certain structure. fast almost no effective large amount organic matters still exist the bio-char, while it largest specific surface area after 800°C. Therefore, is kind by-product process making bio-oil EC worthy further exploration. As concentration impregnated solution increased, first increased then decreased. impregnation 3 mol/L highest (1128.85 m2/g) volume (0.789 cm3/g). If processes were mixing EC, cell tissue reserved. sample prepared 2 g dried 0.1 powder has (724.66 better best 5°C/min for 2°C/min method.
