Ni-Co/TiO2对糠醛制环戊酮、环戊醇的催化性能

Catalysis Performance of Ni-Co/TiO2 for Production of Cyclopentanone and Cyclopentanol from Furfural

以TiO2为载体负载双金属活性组分Ni-Co,采用浸渍法制备催化剂,用于糠醛催化加氢生成环戊酮和环戊醇的反应,并探讨了Ni-Co负载量、反应时间、反应温度、反应压力对产物的影响。通过XRD、BET、H2-TPR、SEM等表征方法对催化剂的构成及反应机理进行了讨论。结果表明,Ni和Co质量比1∶1制备的催化剂10%Ni-10%Co-TiO2,其在优化反应条件下催化糠醛加氢生成环戊酮和环戊醇的产率分别为53. 4%和17. 1%。

TiO2 was used as a carrier to load the bimetallic active component Ni-Co,and the catalyst was prepared by a typical wetness impregnation method and was used in the reaction of furfural catalytic hydrogenation to cyclopentanone and cyclopentanol.The effects of Ni-Co loading,reaction time,reaction temperature and reaction pressure on the products were also discussed.The composition and reaction mechanism of the catalyst were discussed by means of XRD,BET,H2-TPR and SEM.In the catalytic hydrogenation of furfural with 10%Ni-10%Co-TiO2,under the optimized conditions,the formation rates of cyclopentanone and cyclopentanone reached 53.4%and 17.1%respectively.
