综述了近年来催化剂载体的热稳定性及其在催化燃气涡轮机燃烧室中的应用研究进展。为了开发高温燃烧催化剂，耐热催化剂的开发受到了相当大的关注。La、Si、Ba等添加剂的使用，是提高氧化铝基载体材料热稳定性的一种有前途的方法。制备路线也影响操作温度下的表面积和孔结构。从过渡型氧化铝的固相烧结机理探讨了这些影响因素。作者开发了一种贵金属氧化铝基催化剂，六铝酸盐，作为热稳定的燃烧催化剂，可在1200摄氏度以上使用。在这篇综述的后半部分，我们讨论了六铝酸盐的基本催化性能和实际应用于燃气涡轮机燃烧室的结果。
Recent studies concerning thermal stabilization of catalyst supports and their application to a catalytic gas turbine combustor were reviewed. Development of heat-resistant catalysts has received considerable attention for the development of high-temperature combustion catalysts. The use of additives such as La, Si, Ba, etc., is a promising way to improve the thermal stability of alumina-based support materials. Preparation routes also influence the surface area and the pore structure at operation temperatures. The effects were discussed from the solid state sintering mechanism of transition alumina. The authors have developed a noble alumina-based catalyst, hexaaluminate, as a thermally stable combustion catalyst, which can be used above 1200 degrees C. In the second half of this review, we discussed fundamental catalytic properties of hexaaluminates and the results of practical applications to a gas turbine combustor.
