Teaching Experiment Design on Preparation of CuMnAl Catalyst and its Performance for 1,6-hexanediol Dehydrogenation
Cu-based catalysts can effectively catalyze the selective dehydrogenation of 1,6-hexanediol to ε-caprolactone,and related research is of great scientific importance and also of industrial interest.The catalyst preparation conditions and reaction process parameters will greatly affect the dehydrogenation performance,namely the conversion rate of 1,6-hexanediol and the selectivity to ε-caprolactone.Based on this,a teaching experiment was designed to investigate the effects of calcination temperature during the preparation process and reaction temperature on the structure of CuMnAl catalyst and its performance for 1,6-hexanediol dehydrogenation.The content mainly includes the preparation of CuMnAl catalysts,the side crushing strength experiment and the testing of 1,6-hexanediol dehydrogenation performance.Through this teaching experiment,students can acquire the cutting-edge developments in relevant scientific research,have a certain understanding of the catalyst preparation process of co-precipitation and the evaluation of gas-solid dehydrogenation reactions in fixed bed,which helps to comprehensively improve students'innovation skills and scientific literacy.
