Summary: Heterogeneity in feedstock poses a challenge in the conversion of herbaceous lignocellulosic biomass to biobased products. Different anatomical tissues in corn stover respond differently to pretreatment and enzymatic hydrolysis, highlighting the need for tailored processing methods. Predictive correlation of near-infrared spectra to biomass chemical composition shows potential for robust correlations, with Gaussian process regression demonstrating stronger performance compared to partial least squares regression.

Summary: This study investigated the improved performance of corn stover anaerobic digestion by low-temperature hydrothermal pretreatment enhanced with urea. The combination of low-temperature HP with urea improved bio-methane yield, reduced digestion time, and increased volatile solid conversion. The study also observed changes in bacterial and archaeal diversity and composition, with certain species enriched by HP with urea. Urea was found to enhance methanogenic activity and improve the nutrition balance in the AD system.

Summary: This study proposes the use of red mud as a catalyst for steam gasification of corn stover to produce high-quality reducing gas. The results show that increasing the reaction temperature promotes the production of CO, CO2, and H2. Fe2O3 promotes gas-phase reactions, while Al2O3 facilitates the production of CH4 and H2. The presence of CaCO3 inhibits certain reactions and reduces the production of H2. Red mud exhibits superior catalytic performance compared to pure Fe2O3.

Summary: Bioenergy is a clean and renewable energy source that reduces dependence on fossil fuels and is sustainable, economically viable, and socially acceptable. It aligns with United Nations Sustainable Development Goals (SDGs). The design of a green and sustainable Biomass Supply Chain (BSC) is crucial for successful commercialization of bioenergy. However, there are challenges in terms of emissions, economy, and socio-cultural aspects that need to be addressed to achieve sustainable development using bioenergy. Advanced tools and techniques such as artificial intelligence and Life Cycle Assessment (LCA) are recommended for achieving global deployment of bioenergy with net zero emissions.

Summary: This study focuses on the pyrolysis of corn stover using an innovative infrared heated reactor to produce high-value bio-oil and gaseous products. The results show that infrared heating technology effectively suppresses secondary reactions, leading to higher bio-oil yield compared to electric heating technology. Bio-oil yield increases initially with temperature and then decreases, reaching a maximum at 550 degrees C.

Summary: In this study, a calcium modified biochar (CaBC800) was successfully fabricated to simultaneously remove phosphate and tetracycline from wastewater. The experimental results showed that CaBC800 had high adsorption capacities for both pollutants and the adsorption process followed pseudo-second-order kinetics and Langmuir adsorption isotherm. Chemical precipitation and ligand exchange were the main mechanisms for phosphate adsorption, while hydrogen bonding and pi-pi interactions were the main mechanisms for tetracycline adsorption.

Summary: With catalytic pyrolysis becoming the most efficient thermal treatment for biomass, scholars have been searching for catalysts with high economic and catalytic performances. This study investigated the use of red mud as a catalyst for biomass pyrolysis to produce high-quality pyrolysis gas. Fe2O3 was found to be the most dominant catalytically active ingredient in red mud, contributing to improved carbon conversion and hydrogen yield. Additionally, the stable pore structure and chimeric structure of the red mud greatly enhanced its catalytic performance, leading to a significant increase in hydrogen yield.

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.
