Summary: Co-pyrolysis of biomass with waste tire can improve bio-oil quality and mitigate environmental issues. Positive synergistic effects were observed in this study when corn stover and waste tire were co-pyrolyzed. Kinetics analysis revealed the activation energy of each pseudo-component, and the reaction mechanism was determined. The results provide valuable information for scale-up of the co-pyrolysis process.

Summary: Mathematical deconvolution (MD) is a simple method for solving independent multistep kinetics, but its efficiency is questionable in certain cases. This study examines the adjustability of the Fraser-Suzuki function (FSF) for different models and analyzes an example of deconvolution. The results demonstrate that FSF fit is not satisfactory for d alpha/dt vs t curves with sharp peaks and sudden decays. Therefore, the use of MD should be cautious and alternative approaches should be considered.

Summary: Hydrogen peroxide pretreatment was applied for fast pyrolysis of corn stalks, and it was found that the pretreatment effectively promoted lignin depolymerization and decreased the reaction activation energy. The pretreatment also increased the cellulose content and removed alkali and alkaline earth metals from the biomass. The pH of the hydrogen peroxide solution affected the removal of lignin and ash by the pretreatment, and the composition of bio-oil changed significantly, with a significant increase in the relative content of levoglucosan after pretreatment.
