摘要

绝热预重整是现代合成气生产中使用的一种低温蒸汽重整工艺。催化剂失活在绝热预成型设计中起着重要的作用,低温操作需要高活性、耐中毒的催化剂。本文提出了导致预成型催化剂失活的化学反应、中毒机制和孔隙扩散的复杂相互作用模型

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