Study on the Performance of Furfuryl Alcohol Hydrogenation Catalyst under Mild Conditions
In this paper,Ru/C,Ru/Al2O3,Pd/C,Pd/Al2O3,Pt/C,and Raennie nickel catalysts were selected for the kettle reaction of furfuryl alcohol hydrogenation.It was found that the Ru/C catalyst had good reactivity performance in the hydrogenation of furfuryl alcohol to tetrahydrofurfuryl alcohol.The effects of solvent,reaction temperature,hydrogen pressure,reaction time,and catalyst dosage on the reaction under the action of the catalyst were studied,and the process conditions were optimized.The optimal process conditions were obtained:isopropanol was used as solvent,the reaction temperature was 60 ℃,the hydrogen pressure was 3 MPa,the reaction time was 6 h,the mass ratio of raw materials to catalyst was 20∶1,the conversion rate of furfuryl alcohol reached 100%,and the selectivity of tetrahydrofurfuryl alcohol was greater than 95%.
