Abstract

The remarkable enhancement of phenolic monomer generation and hydrogen was achieved through catalytic pyrolysis of Douglas fir over nanocellulose derived biochar catalyst for the first time. The main compositions of produced bio-oil were phenolic monomers, furans, and naphthalenes, etc., in which the phenolic monomers were dominant compositions. And at the temperature of 650 °C and 3 of biochar to biomass ratio, the quantification results showed that the concentration of phenol was increased to 53.77 mg/mL from 15.76 mg/mL of free of biochar catalyst. The concentration of cresols were facilitated to 44.51 mg/mL from 20.95 mg/mL, while the concentration of dimethylphenols reduced to 7.76 mg/mL from 9.11 mg/mL. Up to 85.32 vol% of hydrogen was observed, increasing from 45.53 vol% of the non-catalytic process. After 15 cycles of reuse, biochar catalysts still favored to produce a much higher concentration of phenolic monomers and hydrogen than that of absence of biochar catalysts.
