Special Issue Information

Dear Colleagues,

In the pursuit of sustainable energy solutions, chemical engineering plays a crucial role in developing innovative approaches for energy storage. This special issue explores the potential of ceramic materials integrated with chemical engineering techniques for clean and efficient energy. Ceramic materials offer promising thermal and chemical stability for energy storage. Researchers optimize their composition, structure, and synthesis, and engineer surface properties to enhance performance and reliability. The combination of chemical engineering and ceramics enables exciting advancements in batteries and supercapacitors, enhancing energy storage capacity while addressing cost, safety, and environmental challenges. Fueling the future with chemical engineering approaches in ceramic materials holds the potential to revolutionize renewable energy systems, promote sustainability, and reduce fossil fuel dependence. Ongoing research and technological advancements are unlocking new horizons in clean energy storage, paving the way for a brighter, greener future.

Abstract

This manuscript presents an experimental study focusing on the combustion of magnesium in an atmosphere depleted of oxygen. The study explores various mixtures of carbon dioxide and nitrogen, examining their impact on the combustion performance. The experimental design involved evaluating how the carbon content influences combustion parameters. Temperature profiles were analyzed to elucidate different stages of the combustion process. Furthermore, the effects of pressure (2 and 3 ata) and the composition of CO₂-N₂ mixtures (10%, 19.5%, 35%, 48%, 72%, and 80% CO₂ content) on magnesium combustion, including ignition time, maximum temperature, and post-combustion temperatures, were investigated. The results revealed a substantial impact on the ignition delay and combustion time, with the ignition delay decreasing with higher chamber pressure. The combustion process, especially with regard to the ignition time and heat of combustion, was notably affected by CO₂ concentration. The morphology of the combustion residue from the magnesium microparticles was characterized using scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (SEM-EDX). The reaction of Mg with CO₂ represents a promising energy source, quickly releasing a substantial amount of heat with a very low quantity of Mg. The estimated value of the heat of combustion for magnesium in N₂-CO₂ atmosphere is 78.4 kJ mol⁻¹. Full article
