Research progress on copper-based catalysts for ethanol catalytic dehydrogenation to acetaldehyde
摘要
Abstract
The catalytic dehydrogenation of ethanol to acetaldehyde is one of the key technological pathways for the efficient utilization of coal-based ethanol.The development of efficient catalysts,especially copper-based catalysts,plays a crucial role in influencing the industrialization of this technology.The researches on copper-based catalysts for the catalytic dehydrogenation of ethanol to acetaldehyde are summarized.This includes the types of catalyst supports(unsupported,SiO2,ZnO,ZrO2,Al2O3,and carbon),precursor types,catalyst modification,and catalyst preparation methods,all of which have an impact on catalyst performance.Among them,SiO2 and carbon are considered ideal catalyst supports,and copper-based catalysts prepared using organic copper precursors,K or C additives,and ammonia evaporation method exhibit better performance.However,the catalysts'reported lifetimes currently fall short of industrial requirements,or the ethanol concentration in the feedstock is relatively low(≤15%,volume fraction).To address these issues,Shaanxi Yanchang Petroleum(Group)Co.,Ltd.and Lanzhou Institute of Chemical Physics,Chinese Academy of Sciences jointly developed an efficient catalyst suitable for pure ethanol feeding,with a catalyst life of more than 2600 h,which has a good industrial application prospect.关键词
