The article delves into a research study conducted at the Shanghai Institute of Technology, focusing on investigating the granule reaction of two-micron aluminum powders with water at low temperatures. The researchers utilized differential scanning calorimetry (DSC) to analyze the initial exothermic temperature and then employed adiabatic accelerated calorimetry (ARC) to study the exothermic reaction under adiabatic conditions. The primary objective was to gain insights into the Al-water reaction in a reactor with no induction time, specifically looking at hydrogen production and particle size variation. Notably, through focused beam reflectance measurement (FBRM) analysis, the researchers observed intriguing trends in particle sizes during the Al-water reaction. The 3µm aluminum powder experienced a 189% increase in particle size, while the 25µm aluminum powder decreased by 29%, ultimately converging to similar final sizes around 13.89µm. The study not only explained the process of Al-water reaction but also provided an analysis of hydrogen production and developed a kinetic model to understand the reaction better. This research contributes significantly to the field of energy systems and chemistry, particularly in exploring innovative ways for potential hydrogen production. Overall, the sentiment of the article is positive, emphasizing the valuable insights gained from the study.
