Selective aromatic production from fast pyrolysis of sugarcane bagasse lignin over ZSM-5 catalyst

Organosolv lignin extracted from sugarcane bagasse (BG-lignin) and commercial grade lignin (Comm-OS) were use as starting materials in this study. From our previous work, aromatic furan (2,3-dihydrobenzofurn) was mainly produced from fast pyrolysis of BG-lignin and Comm-OS at 400–600 °C while alkyl...
