Catalyst deactivation in adiabatic prereforming: Experimental methods and models for prediction of performance

Abstract

Adiabatic prereforming is a low-temperature steam reforming process used in modern syngas production. Catalyst deactivation plays an important role in design of adiabatic prereforming and the low-temperature operation requires a high-activity catalyst with resistance to poisoning. This paper presents a model for the complex interaction of chemical reactions, poisoning mechanisms and pore diffusion that results in deactivation of prereforming catalyst
