Ceramic Membrane Fabrication and Characterization for High-Temperature Gas Filtration in Chemical Reactors

Abstract

High-temperature gas filtration is essential in chemical reactor systems to ensure process efficiency, catalyst protection, and reduction of particulate emissions under harsh industrial operating conditions. Conventional filtration materials often experience thermal degradation, limited chemical resistance, and reduced structural stability at elevated temperatures. This study investigates the fabrication and characterization of ceramic membranes for high-temperature gas filtration in chemical reactor applications. The proposed membrane system was developed using advanced ceramic materials engineered to provide high thermal stability, mechanical strength, chemical resistance, and efficient particulate separation performance. A comprehensive experimental investigation was conducted to evaluate the influence of fabrication parameters, sintering temperature, pore structure, membrane thickness, and ceramic composition on filtration efficiency and structural integrity. Advanced characterization techniques including scanning electron microscopy, porosity analysis, thermal stability evaluation, and mechanical strength testing were employed to assess membrane morphology and performance characteristics. Filtration performance analysis demonstrated significant improvements in particulate removal efficiency, thermal resistance, and pressure stability under high-temperature gas flow conditions. The ceramic membranes also exhibited enhanced durability and resistance to thermal shock, corrosion, and fouling during prolonged reactor operation. Comparative evaluation revealed superior gas filtration performance and operational lifespan compared to conventional polymeric and metallic filtration systems in aggressive chemical processing environments. Furthermore, optimized pore distribution and membrane architecture contributed to improved gas permeability and reduced pressure drop during continuous filtration processes.
