Abstract

Microwave assisted catalytic pyrolysis was investigated to convert Douglas fir to bio-oils by ZSM-5 Zeolite catalyst. Central composite experimental design (CCD) was used to optimize the catalytic pyrolysis process. The effects of reaction time, temperature and catalyst to feed ratio on the bio-oil, syngas, and biochar yield were determined. The maximum volatile yield ∼ 98% appeared at the reaction time 12 min, reaction temperature 600°C and catalyst to biomass ratio 4. GC/MS analysis results showed that the bio-oil contained a series of important and useful chemical compounds: phenols, aromatic hydrocarbons, and furan derivatives. Comparison between the bio-oils from microwave pyrolysis with and without catalysts showed that the catalyst increased the content of aromatic hydrocarbons and phenols.
