| Abstract: | Pyrolysis is the main way to transform biomass into energy, and the technology of biomass pyrolysis has been widely studied. Based on literatures, the main pyrolysis products of different kinds of simple biomass (protein, carbohydrate, lignin) and complex biomass (algae, straw, sawdust and lipid) were summarized, and the yield change trend of some products under different conditions was pointed out. At the same time, this paper analyzed the influence of polymerization degree on the pyrolysis products of cellulose, compared the pyrolysis characteristics of cellulose and hemicellulose, and introduced the influence of some groups in lignin on its pyrolysis. Then, the impact of pyrolysis temperature, heating rate and residence time on the pyrolysis products of algae, straw, sawdust and complex lipids were analyzed. The characteristics of the two methods (catalytic hydrogenation and catalytic cracking) for improving the quality of bio oil were introduced, and the effect of catalyst in catalytic cracking was summarized. |
