Summary: A novel method for high yield and high calorific value syngas production has been proposed through co-pyrolysis of light bio-oil leached bamboo and heavy bio-oil. The results showed that the synergistic effect during the co-pyrolysis led to a higher gas yield and a higher content of combustible gases, resulting in high-quality syngas enriched in H-2 and CO.

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: 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: This study aims to produce N-doped biochar by co-pyrolysis of nutrient-rich household and horticultural wastes and provide optimal conditions for production. The results showed that the ratio of household to horticultural wastes had the most critical effect on the biochar yield. The optimum N-doped biochar yield of 26% was achieved at a household-to-horticultural waste ratio of 1.5 without using a catalyst. Additionally, adding household waste significantly increased bio-oil yield, while increasing the catalyst amount raised gas yield and horticultural waste favored biochar formation.

Summary: The compatibility of fast-pyrolysis bio-oil with elastomer and plastic materials commonly used in fuel storage and delivery systems was studied. Elastomers showed significant swelling in the bio-oil, especially fluorocarbons and acrylonitrile rubbers. In contrast, plastic materials were less affected by the bio-oil due to their denser and more rigid molecular structures.

Summary: This study explored anaerobic digestion and dark fermentation as green pre-treatments for seaweed biomass prior to pyrolysis. The biological pre-treatments significantly affected the composition and structure of the seaweeds, leading to changes in thermal degradation and volatile profiles during pyrolysis, with potential for generating biooil similar to petroleum-based composition.

Summary: Conversion of non-edible RTO into bio-oil by catalytic pyrolysis using dolomite as a catalyst, without prior calcination or treatment. Dolomite enhanced bio-oil yield and reduced char formation at higher pyrolysis temperatures. Dolomite also improved the composition and physical properties of bio-oil, including viscosity, calorific value, and density, and reduced the carboxylic acid content through esterification reaction.

Summary: A novel two-stage solvent-assisted batch catalytic hydroprocessing method was developed to upgrade intermediate pyrolysis bio-oil to produce blended liquid fuels with approximately 23 wt% hydrocarbon-rich biofuel content. The first stage reactions involving mixtures of dodecane and bio-oil, hydrogen gas, and metal-supported catalysts suppressed char formation and obtained up to 80 wt% liquid organic products dominated by ketones and phenols. The second stage reactions with the first stage organic liquid products gave over 90 wt% of blended liquid fuel. Pt/Al2O3 catalyst deactivated in the first stage but remained stable in the second stage.

Summary: This study investigates the thermal and catalytic hydrotreatment of a simulated pyrolysis oil and compares the effects of reaction conditions and different oxygenated organic compounds on product yields and properties. It finds that the presence of oxygenated furan and sugar compounds significantly affects the yield of liquid product and promotes solid formation. Stabilizing furan, especially with attached carbonyl groups and sugar derivatives, is important for improving upgrading efficiency in pyrolysis oil.

Summary: This paper proposes the use of a coating layer on a commercial SOFC to enhance its fuel adaptability. Three different ceramics were evaluated as protective layers for the cells fed with dry biogas or bioethanol. The results showed that the additional layer increased the cell resistance, negatively affecting its performance, but improved the effectiveness of using simulated biogas and ethanol.

Summary: This research focuses on the development of biogas sector in Colombia, a developing country. The study finds that Colombian research mostly concentrates on agricultural waste substrates, inocula, and co-digestion, while full-scale digesters' performance research is lacking. A survey reveals that 79% of the installed digesters in Colombia are psychrophilic low-cost tubular digesters. The existing regulations for biogas in Colombia are not suitable for low-cost digesters and are borrowed from developed countries, disregarding the national context. The research presents five case studies analyzing the barriers and opportunities for AD technology, driven slowly by national networks comprising farmers, NGOs, and academia.

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.
