In this work, co-pyrolysis of Indonesian oil sands and corn straw was investigated to evaluate the potential synergetic effect. Thermogravimetric analysis was conducted to study the thermal decomposition behaviors of individual and blend feedstocks. Improved pyrolysis characteristics and higher conversion were observed, indicating a remarkable synergetic effect. Moreover, co-pyrolysis experiments were carried out using a fixed bed reactor. The results showed that the co-pyrolysis liquid product yield was increased, while the formation of solid residue was reduced, suggesting a higher conversion. The liquid product characterization by gas chromatography–mass spectroscopy also indicated the significant synergetic effect on the liquid chemical composition. Valuable phenols and alcohols were increased, while unstable aldehydes were decreased, suggesting the chemical interactions between two feedstocks during the co-pyrolysis process. The yield improvement and compositional variations of the co-pyrolysis liquid product were beneficial for its use as fuel and chemical feedstock.
