VAH型气相醛加氢催化剂的工艺研究

Study on process of VAH-type aldehyde hydrogenation catalyst by gas-phase method

在试验室制备、评价所研制的醛加氢催化剂的基础上 ,进行了催化剂的工业放大生产和在化工二厂丁辛醇装置上的单管侧线放大试验 ,结果重复了实验室的小试水平 ,醛加氢催化剂各项性能优于进口的醛加氢催化剂G - 6 6B - 1,所研制的催化剂具有良好的活性、选择性和稳定性。具备了催化剂的国产化和工业应用的水平。

After laboratory preparation and performance evaluation of VAH-type aldehyde hydrogenation catalyst,we carried out industrial scale-up manufacture and single-tube sidetrack industrial scale-up trial of VAH-type catalyst at n-BuOH?2-EH devices which belongs to No.2 Chemisty Work the test results and laboratory evaluation results achieved a good repeatability,the results indicated that the properties of VAH-type aldehyde hydrogenation catalyst are better than that of imported aldehyde hydrogenation catalyst G-66B-1,and the VAH-type catalyst possesses excellent activity?selectivity and stability?Therefore the said catalyst is a kind of good domestic catalyst and can be used in the industrial devices.
