Inorganic membranes are becoming increasingly interesting for CO2 gas separation processes considering their potential in CO2 capture and storage for mitigating global warming. Porous alumina filters with the ability of CO2 gas separation were prepared by modifying four types of silane coupling agents: 3-Aminopropyltriethoxysilane (APTES), 3-Ureidopropyltriethoxysilane (Ureido), Octadecyltrimethoxysilane...
Agglomerated sub-micrometer-sized alumina particles were pulverized using a novel method. A high-density polyethylene (HDPE) cup equipped with stainless steel mesh turned at a 500–2000rpm revolution rate and a 200–800rpm rotation rate. A suspension passes through the small mesh openings, and turbulent flow and high shear stress was generated. The sample's particle size distribution before mesh treatment...
