助剂钾对镍基催化剂性能影响研究进展
A review of potassium promoter effect on nickel-based catalyst performance
摘要
Abstract
Nickel-based catalyst is one of the most promising catalysts in biomass gasification and tar reforming,but it deactivates fast due to carbon deposition,compromising its economic efficiency. Promoter addition can improve both its resistance to carbon deposition and stability. Potassium can be used as a catalyst for biomass gasification and tar reforming,and it significantly suppresses the coke deposition on catalyst. The present review is focused on the influence of potassium promoter on the performance of nickel-based catalyst,including its resistance to carbon deposition,catalytic activity, coke formation and gasification mechanism. The addition of potassium promoter can significantly suppress coke formation and catalyst sintering,and improve its thermal stability. Investigations on various species of potassium promoter and different addition methods are suggested for future research,in order to obtain essential mechanism and performance details,and to produce a novel nickel-based catalyst with high activity,high resistance to carbon deposition and long lifetime for biomass gasification.关键词
