Abstract
In this study, pyrolysis of waste wood polymer composite (WPC) was investigated using thermogravimetric analysis (TGA) and a fixed bed reactor. TGA results showed that the decomposition of biomass and polymer yield two distinct temperature ranges. The average activation energy for the decomposition was 297 kJ/mol. The main gas species released from the pyrolysis of waste WPC in the fixed bed reactor were CO, CO2 and C1-C4 hydrocarbons. As temperature increased from 425 °C to 575 °C, the amount of hydrocarbons (mainly C1) increased. The moisture content of the product bio-oil was about 5%, being much smaller than that of typical biomass-derived oil. Deoxygenation reaction became more active when the reaction temperature increased, resulting in reduced acid and oxygenate contents and increased phenolic and hydrocarbon contents.
