Palladium Catalyst Systems For Reforming In Cyclic Flow Reactors

Abstract

Palladium-based catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. It has been discovered that loss of catalytic activity for reforming over time can be reduced or minimized for palladium-based catalyst system by operating the reactor/performing a reaction cycle so that the portion of the reaction environment containing the palladium-based catalyst system is not exposed to oxidizing conditions at temperatures between 600° C. and 900° C. Optionally, the reactor can also be operated/the reaction cycle can also be designed so that during a reforming cycle, the peak temperature in the portion of the reaction environment containing the palladium-based catalyst system is 1300° C. or less.
