Summary: This paper presents the results of numerical simulation on the gasification process in a downdraft gasifier for producing high hydrogen content syngas. The feasibility of using dark fermentation digestate as feedstock for thermochemical conversion using air as the oxidizer was investigated. The concentrations of the main components of the syngas were obtained through numerical studies. The maximum hydrogen content in syngas was achieved at an equivalence ratio of 0.45.

Summary: In this study, a predictive model for fixed bed gasification properties was developed using MLP neural network. By considering the physicochemical composition of the biomass and the reactor operating conditions, the MLP model achieved reasonable accuracy in predicting the gas composition and lower heating value. The results of this study demonstrated that MLP can effectively replace costly experimental investigations to study the gasification process.

Summary: This study aimed to analyze the syngas production from co-gasification of organic waste pellets using Renewable Densified Fuels in an open-top downdraft fixed bed gasifier. The results showed that higher temperatures led to higher lower heating values of syngas, and an increase in pellet fuels also increased the LHV syngas value. The experimental results also demonstrated a visually low tar content and ash particles in all compositions.

Summary: Gasification is a technically feasible method for municipal solid waste valorization, which can meet emission limits and reduce landfill burden. This study investigates the potential of using paper-rich commercial refused-derived fuel (RDF) with high ash content for gasification and co-gasification. The results suggest that co-gasification can reduce overall ash content and increase the heating value of the gas produced.

Summary: This study investigated the use of olive mill solid waste (OMSW) as a fuel in a pilot-scale downdraft gasifier. After pelletization and characterization, gasification experiments were conducted with air as the gasifying agent. The performance of the gasifier was evaluated through the analysis of syngas composition, solid residues, and energy balances. The results showed that OMSW has substantial energy potential and could help reduce reliance on fossil fuels, but there were concerns regarding ash melting point, tar content in syngas, and NOx emissions.

Summary: The co-gasification of RDF and biomass is an efficient technology for MSW utilization, with higher temperature and ER values promoting syngas yield. Co-gasification demonstrated synergistic enhancements in carbon conversion efficiency, gas yield, and cold gas efficiency. Positive synergy effects were observed at lower ER and higher temperatures, while negative synergy effects tended to appear at higher ER values.

Summary: The study investigated a small-scale downdraft gasification system integrated with an internal combustion engine for the sustainable conversion of biomass into electricity. Different measurements and analyses were performed to monitor and evaluate the quality of feedstock and products. The results showed that with increasing electrical loads, the lower heating value of syngas decreased, while cold gas efficiency and carbon conversion efficiency increased. The study also proposed a modified quasi-thermoequilibrium model to predict syngas composition, tar yields, and char released during the gasification process.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
