The catalytic hydrogenation of D-glucose over a 3 wt% Ru/C catalyst was studied varying the operating conditions in mild range to optimize obtention D-sorbitol. stirring speed, temperature, pressure, and initial glucose concentration were varied between 250 - 700 rpm, 343 383 K, 0.5 2 MPa, 0.033 0.133 M, respectively. To verify absence mass transport limitations, diffusion reagents gas-liquid i...
