Summary: The scope of this paper is to investigate the utilization of gasification char (GC) as a sorbent material for capturing mercury from coal combustion flue gas. The aim of the study is to determine the absorption capacities of GC produced from softwood pellets (SWP) and solid recovered fuel (SRF), and evaluate the influence of particle size and hot steam activation. Promising results were obtained with 0.5-2 mm particle size and hot-steam activation, reaching mercury removal efficiencies of 76.5% for SWP GC and 62.3% for SRF GC. This study suggests a promising approach for waste utilization in the energy sector, contributing to the sustainability of the circular economy and addressing environmental concerns.

Summary: Hydrogen production through oil sludge gasification with steam is significant for industrial hazardous waste treatment and resource conservation. The process showed optimal hydrogen yield at 800 degrees Celsius with an SOS ratio of 0.3:1. Char yield post-gasification was high, necessitating incineration which could be divided into three stages. Gasification combined with char incineration is an effective approach for solid waste utilization, recovering hydrogen energy and reducing environmental risks.

Summary: This study focuses on char gasification in steam for generating syngas in a two-stage gasification technology for high-ash coal. Controlled experiments were conducted to investigate the dependence of char reactivity on temperature, gas composition, flow rate, and carbon conversion rate. The results showed that small particles have higher reactivity compared to bigger particles, making them suitable for pilot-scale operations. Pilot-scale experiments were also carried out in an oxy-steam environment, and the results were compared to simulated experiments for small particles. The addition of oxygen with steam improved the reactivity of char gasification, but led to a decrease in the calorific value of the gas.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
