Catalyst system for reforming in circulating flow reactor and preparation and use thereof

Catalyst systems for hydrocarbon reforming, as well as methods of using such catalyst systems, are provided. The catalyst system may be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer may correspond to a thermally stable metal oxide support layer, such as a thermally phase stable metal oxide support layer at a temperature of 800 DEG C to 1600 DEG C. The catalyst system may be beneficial for use in a cyclic reaction environment, such as a countercurrent reactor or other type of reactor that operates using streams of opposite directions and different times within the reaction cycle. 提供了用于烃重整的催化剂体系，以及使用这样的催化剂体系的方法。所述催化剂体系可以沉积或以其它方式涂布在表面或结构，如整料上，以实现改进的活性和/或结构稳定性。所述金属氧化物载体层可对应于热稳定的金属氧化物载体层，如在800℃至1600℃的温度下热相稳定的金属氧化物载体层。所述催化剂体系可以有益于在循环反应环境中使用，如逆流反应器或在反应周期内使用相反方向和不同时间的流操作的其它类型的反应器。
