Glucose hydrogenation in a membrane trickle-bed reactor

AICHE JOURNAL, Issue 11 2003
Victor Diakov
The concept of membrane distributed feed to a packed-bed reactor is applied to multiphase catalytic reaction systems. The expected benefits of this approach include enhanced reactant conversion. The concept may be applied to a wide variety of reactions conducted over trickle-beds and is supported experimentally for the reaction of glucose hydrogenation to sorbitol. [source]

Abstract A new process for D -glucose hydrogenation in 50 wt% aqueous solution, into sorbitol in a 1.5 m3 gas,liquid,solid three-phase flow airlift loop reactor (ALR) over Raney Nickel catalysts has been developed. Five main factors affecting the reaction time and molar yield to sorbitol, including reaction temperature (TR), reaction pressure (PR), pH, hydrogen gas flowrate (Qg) and content of active hydrogen, were investigated and optimized. The average reaction time and molar yield were 70 min and 98.6% under the optimum operating conditions, respectively. The efficiencies of preparation of sorbitol between the gas,liquid,solid three-phase flow ALR and stirred tank reactor (STR) under the same operating conditions were compared.
