Abstract

Desilicated Beta (DeBeta) was applied as the catalyst to the catalytic pyrolysis of waste lignin for the formation of aromatic hydrocarbon, and its performance was compared with that of the unmodified Beta. Large amounts of oxygen containing pyrolyzates were efficiently converted to stable aromatic hydrocarbons over both Beta and DeBeta catalysts. Compared to Beta, DeBeta exhibited the higher performance for the formation of aromatic hydrocarbons due to the enhanced diffusion efficiency through the mesopore.
