Bio-oil production from pyrolysis of waste sawdust with catalyst ZSM-5

Slow pyrolysis is characterized by a low heating rate and high reaction time. The products are bio-char, bio-oil and bio-gas. In bio-oil, there are a variety of chemical compounds. Leading aromatic chemicals such as furfural, creosol and catechol were a focus of this study. In non-catalytic conditions, the slow pyrolysis temperature was 350, 400, 450, 500, and 550 °C. The experiment was conducted in catalytic condition using ZSM-5 catalyst to produce more aromatic chemicals. In this research the slow pyrolysis experiment was conducted in non-catalytic and catalytic conditions. In non-catalytic condition, a large amount of bio-oil was produced at 500 °C. The peak area of furfural, which is a valuable organic chemical, was highest value at 400 °C. In the catalytic condition the temperature was fixed at 400, and 500 °C. The result analysis evaluated the mass yield of bio-oil and GC–MS data for quantitative and qualitative analysis.
