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 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: 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 evaluated the performance and emissions of direct injection diesel engines using blends of diesel-biodiesel-esterified pyrolysis bio-oil (D-B-EPB). The results showed that a fuel blend consisting of 30% diesel, 60% biodiesel, and 10% EPB (D30B60EPB10) met the density and viscosity requirements of diesel standards. The D30B60EPB10 blend exhibited performance comparable to diesel while being more environmentally friendly in terms of reducing carbon monoxide, carbon dioxide, nitrogen oxide, and smoke opacity.

Summary: A new method of upgrading pyrolysis products through co-pyrolysis polygeneration and bio-oil recycling was proposed in this study. The results showed that the leaching pretreatment effectively removed alkali metals from pine wood, improving the quality and energy yield of bio-oil during subsequent pyrolysis. The co-pyrolysis of pine wood and heavy bio-oil had a synergistic effect, increasing the mass yield of biochar and pyrolysis gas while improving the contents of CO and C2+ gases in the gaseous products. This method provides a potential way to classify and utilize light and heavy components of bio-oil.

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: Biomass-to-liquid thermochemical routes, such as fast pyrolysis, are promising methods for converting waste biomass into sustainable hydrocarbon fuels. However, the bio-oil derived from pyrolysis has poor quality and requires extensive upgrading before it can be used as a jet fuel. Catalytic cracking and hydrodeoxygenation are the most promising approaches for upgrading bio-oil to bio-jet fuel. Further research is needed to understand the mechanistic aspects of raw bio-oil upgrading.

Summary: The use of biomass as an alternative energy source is extensively studied due to high value products like gamma-valerolactone that can be derived from biomass. This study demonstrates the efficient production of gamma-valerolactone from furfural using sepiolite supported Zr catalysts. Catalysts with 9-17 wt% ZrO2 showed the highest yield, while catalysts with 9 wt% ZrO2 exhibited the highest turnover frequencies (TOFs) due to well-dispersed ZrO2 nanoparticles. Lewis and Bronsted acid sites play essential roles in the one-pot transformation of furfural to gamma-valerolactone. The catalytic results obtained with sepiolite supported Zr catalysts are comparable to those achieved with zeolitic supported Zr catalysts.
