Abstract: Kinetics study on the hydrogenation of glucose to sorbitol on Raney nickel was undertaken at 110 K to 140 K and under pressure 2.0 MPa to 6.0 MPa. Based on the experimental result, a suitable reaction model was selected, i. e. the desorption of sorbitol with reaction between molecularly absorbed hydrogen and absorbed glucose on the catalyst surface could be the controlling step. The intrinsic kinetic equation could be written as:
