Summary: The study showed that catalytic reaction with activated char could increase the relative content of phenolic substances in bio-oil and create more active sites. At higher temperatures, the content of aromatic hydrocarbons in bio-oil increased while oxygen-containing compounds (such as ketones, acids, aldehydes) decreased.

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: This study focuses on the upgrading of biomass-derived bio-oil through catalytic hydrogenation. A new catalyst, Rh/ZrO2, was developed with high deoxygenation ability. Catalytic hydrogenation can remove oxygen from bio-oil and reduce its oxygen content, thereby enhancing its potential as a biofuel.

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: 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 review article focuses on the application of catalytic pyrolysis for obtaining high-quality bio-oil and advanced techniques for bio-oil characterization. The results show that two-dimensional gas chromatography technique can identify a majority of chromatograph in bio-oil analysis, but combining with other analytical techniques is needed for accurate quantification of bio-oil components.

Summary: The selection of corrosion-resistant and cost-effective structural materials for biomass-derived oil production, upgrading, and storage has been extensively studied in our laboratory. The wide variety of biomass resources and liquefaction techniques result in products with diverse properties. This paper discusses the materials challenges in three distinct areas. Austenitic stainless steels have generally performed well in the production process at temperatures ranging from 350 to 550 degrees C, although issues such as thicker oxide scales and intergranular attack have been observed. For storage and transport of bio-oil products, organic acids present in the raw bio-oils can cause corrosion to carbon and low-alloy steels. Furthermore, certain subsequent processing methods can lead to corrosion of common austenitic stainless steels during exposure to sulfidizing gas at elevated temperatures. The study identifies cost-effective and sufficiently corrosion-resistant materials for each environment.

Summary: Thermal treatment of spent lithium-ion batteries can produce valuable metals with catalytic activity, which can be used as cheap catalysts for biomass pyrolysis. The study found that PyNCM and PyLCO have good catalytic activity for promoting the devolatilization process of wheat straw and enhancing the cracking of bio-oil to produce more gaseous products (syngas). Additionally, both PyNCM and PyLCO increased the content and yield of H2 in the syngas, with PyNCM showing a more distinct catalytic effect on wheat straw pyrolysis.

Summary: This study developed a nanocellulose/chitosan-based film coated with polylactic acid (PLA) to monitor beef spoilage in real-time. The film displayed a visible color change in response to pH buffer solutions and showed an apparent color change after 5 days as a threshold for beef spoilage. Colorimetric device processing revealed substantial color difference values after 5 days of beef spoilage.
