Summary: This study applied a CO2-enhanced water leaching method to remove alkali/alkaline earth metallic species from biochar and used the demineralized biochar as a catalyst for upgrading pyrolysis biooil. The results showed that the pore structure of the catalyst played a dominant role in increasing phenols contents, while alkali/alkaline earth metallic species enhanced the polymerization of aromatic hydrocarbons and the decarbonylation of oxygenated compounds.

Summary: Catalytic pyrolysis of pine sawdust was utilized to produce valuable alkylphenol compounds by introducing surface active groups, such as metal iron species and oxygen-containing groups, to strengthen the biochar-based catalyst. The presence of these active sites promoted the conversion of pyrolytic intermediates into phenolic compounds during catalytic pyrolysis. The deactivated catalyst could be easily regenerated and showed a good selectivity for phenol production.

Summary: This study synthesized a series of Co-Ce, Co-Fe, and Co-Mg composite metal catalysts and used them to produce furans and ketones from cellulose pyrolysis. The catalyst effectively promoted the depolymerization of cellulose and improved the oxygen transfer behavior. CO2 as a reaction medium influenced the carbon distribution of products, increasing syngas yield and promoting the formation of furans and ketones. These works provide an important pathway for the efficient preparation of furans and ketones from biomass pyrolysis.

Summary: The quality and yield of bio-oil can be improved by co-pyrolysis of heavy bio-oil and bamboo pretreated by light bio-oil leaching. Under the optimal co-pyrolysis conditions, the highest yield and heating value of bio-oil were obtained. Furthermore, the relative contents of phenols and hydrocarbons increased while that of acids decreased in the bio-oil produced by copyrolysis. Predictive models for bio-oil yield and properties were established, providing a foundation for the preparation and utilization of bio-oils.

Summary: The effect of wastewater and NaCl mixture on microalgae growth was studied and it was found that increasing salinity in wastewater led to decreased biomass production but significantly increased lipid content. The addition of Fe2O3 nanoparticles enhanced microalgae productivity. Chlorella vulgaris was identified as a suitable candidate for treating high salinity wastewater.

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.
