Preparation of THF using hydrogenation of furan and catalyzation of Raney Ni

Raney nickel catalyst was used to prepare THF in an autoclave with liquid hydrogenation of furan. The favorable reaction conditions in the process of hydrogenation of slurry reactor were analyzed. The experimental results showed that furan can be absolutely converted into THF, and high conversion and yield rate can be obtained by the use of Raney nickel catalyst under the suitable conditions. Under the following condition: the adding amounts of Raney nickel are from 8.0 percent to 12.0 percent, the hydrogen pressures are in the range from 2.0 MPa to 5.0 MPa, the furan conversion rate is over 99 percent, and the yield rate of THF is about 70 percent .
