The Effects of Catalysts on Pyrolysis Products of Enzymolyzed Straw Lignin

Article Preview

Abstract:

Lignin is depolymerized to small molecule aromatic compounds, which is regarded as one of the effective ways to achieve utilization of lignin resource. In this study, Al and Cu catalysts were loaded onto enzymolyzed straw lignin by the immersion method, and the product distribution of the catalytic pyrolysis of lignin was studied by GC-MS after being extracted by solvents. Results show that both Al and Cu catalysts can promote the lignin pyrolysis reaction. Based on the comparison of the product distribution without catalyst, Al catalyst is benefit to the formation of aromatic hydrocarbons, alcohols and phenols, while Cu catalyst contribute to the formation of hydrocarbons, alcohols and ketones.
