用于乙醇水蒸气重整的负载型金属催化剂失活的研究进展

摘要

负载型金属催化剂的发展直接影响着乙醇水蒸气重整的研究,而造成负载型金属催化剂失活的原因有很多.重点论述了催化剂活性金属烧结和催化剂表面积碳的问题,并对目前所采用的解决办法进行阐述.同时对今后制备抗积碳性能强的负载型金属催化剂的研究方向进行展望.%The study of ethanol steam reforming would be affected by the development of the supported metal catalysts.However,many different factors could lead to catalyst deactivation.This paper focused on two main aspects:Active metal sintering and coke formation.And some solutions currently used were expounded.At the same time,the research direction from the supported metal catalysts with the resistance of carbon deposition was prospected.
