Pyrolysis Characteristics and Catalytic Thermal Cracking of Macroalgae Enteromorpha prolifera
Abstract: Pyrolysis characteristics of Enteromorpha prolifera, cornstalk (grass biomass) and sawdust (woody biomass) were investigated with thermogravimetric analysis (TGA) method. The results showed that Enteromorpha prolifera has lower thermostability compared with cornstalk and sawdust. The kinetics parameters including activation energy and the most probable mechanism functions of the three biomasses were calculated by Coats-Redfren method. Moreover, using sodium carbonate as catalyst impregnated biomass, the pyrolysis process of the three kinds of biomass and the effect of the catalyst with different concentrations were studied with thermogravimetric analysis. The results show that sodium carbonate can decrease the initial decomposition temperature and the maximum weight loss temperature. It has a stronger catalytic effect on cornstalk and sawdust on Enteromorpha prolifera as far as the decrease extent of the temperature is concerned.
