Summary: The gasification process is widely used for bioenergy production, and its high conversion efficiency makes it attractive. Gasification char, a byproduct of gasification, is often treated as industrial waste, despite its attractive qualities. However, its properties depend on the gasification parameters and initial feedstock, requiring careful characterization for suitable applications. This review provides an assessment of gasification and char properties, aiding in the selection of appropriate valorization pathways.

Summary: Established biofuel examples show the potential for sustainable ways to reduce reliance on fossil fuels and mitigate negative effects. The biomass-to-liquid (BtL) route, particularly the Fischer-Tropsch (FT) process, offers a pathway for converting biomass into liquid biofuels. However, technical challenges and high costs still hinder commercial applications. This review synthesizes information on impurities generation and removal techniques in the gasification integrated into the Fischer-Tropsch process (G-FT), proposing a flexible gas cleaning sequence.

Summary: This study evaluated the effect of different amounts of waste-based catalyst (sunflower husks ash) and pressure on the gasification of low-reactive waste fuels (such as tire-char) with steam. The results showed that steam gasification at low temperatures, 1 MPa pressure, and in the presence of 15 wt% catalyst can efficiently obtain gas rich in hydrogen, making it a promising future fuel.

Summary: In this study, machine learning was used to optimize the process conditions for synthesis of mesoporous activated carbon (AC) from biomass, which served as a catalyst support in Fischer-Tropsch synthesis (FTS). The random forest regression (RFR) method achieved the best prediction accuracy for the textural features of AC. The AC prepared under the optimized conditions showed promising potential as a biomass-based catalyst support for FTS, with superior activity and selectivity compared to other catalysts.

Summary: The study reviewed literature on the energy efficiency of biomass-based Fischer-Tropsch plants, highlighting the limited number of techno-economic assessments due to the early stage of Bio-FT technology development. Plant design features for high conversion efficiency and low production costs include feeding biomass at low moisture content, pressurized gasifiers, and using efficient FT catalysts. Despite no correlation between overall efficiency and biofuel production cost, a moderate correlation was found between biomass-to-fuel efficiency and production cost.

Summary: Non-recyclable municipal solid waste can be converted into liquid fuel through gasification and Fischer-Tropsch processes. This study evaluates the carbon intensities of these fuels and examines key factors that could affect their sustainability, such as fossil carbon content, diversion from landfills, and conversion efficiency. The results show a wide range of carbon intensities for fuels produced from different waste streams, some of which may exceed those of petroleum fuels.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: This paper analyzes two metallic inclusions incorporated in Roman raw glass slags, revealing their material composition, corrosion, and internal structure. The results suggest that the metallic bodies were formed during the melting phase when metal scraps were added to color the glass, leading to metal expulsion and agglomeration. This study provides insights into the ancient practice of adding metallic agents to color glass.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

A novel genetic algorithm (PDGA) is introduced to optimize power density and turbine layout. The results show that the PDGA-driven solutions significantly reduce the levelized cost of energy (LCOE) compared to the default layout, and exhibit a convex relationship between area and LCOE or power density.
