Thermal stabilization of catalyst supports and their application to high-temperature catalytic combustion

摘要: Abstract Recent studies concerning thermal stabilization of catalyst supports and their application to a catalytic gas turbine combustor were reviewed. Development heat-resistant catalysts has received considerable attention for the development high-tempearture combustion catalysts. The use additives such as La, Si, Ba, etc., is promising way improve stability alumina-based support materials. Preparation routes also influence surface area pore structure at operation temperatures. effects discussed from solid state sintering mechanism transition alumina. authors have developed noble catalyst, hexaaluminate, thermally stable which can be used above 1200°C. In second half this review, we fundamental properties hexaaluminates results practical applications combustor.
