采用共沉淀法制备CuO-ZnO-A12O3-MnO2复合氧化物为活性组分体系的新型铜基催化剂,并评价其在糠醛选择性加氢制备糠醇过程中的活性,比较Na2CO3、NH4HCO3、H2C2O4三种沉淀剂制得催化剂的活性差异并通过TPR、XRD、ICP、BET等手段表征,结果表明:用Na2CO3作沉淀剂制得催化剂转化率最高.进一步对制备条件进行考察,发现采用A l(OH)3的添加形式和并流共沉淀法有利于提高催化剂的活性,而助剂Mg的添加能有效提高催化剂稳定性. A new Cu-based catalyst was prepared by coprecipitation method to prepare CuO-ZnO-A12O3-MnO2 composite oxide as the active component. The activity of furfural in selective hydrogenation of furfural to furfuryl alcohol was compared. Three kinds of catalysts, Na2CO3, NH4HCO3 and H2C2O4, The results showed that the conversion rate of catalyst was the highest with Na2CO3 as the precipitant.After further investigation of the preparation conditions, it was found that the use of Al (OH) 3 added form and cocurrent coprecipitation method is conducive to improve the activity of the catalyst, and additives Mg can effectively improve the stability of the catalyst.
