✦ Synopsis

This paper presents results of experimental work on the development of a pilot plant fluidized bed reactor for production of I>arabinose using liquor from the fermentation oxidation of D-glucose to D-gluconic acid as starting material. Two electrochemical reactors with a fluidized bed anode of production capacity 0.065 kgh -1 and 0.325 kgh -1, respectively, have been developed. These figures represent five and twenty-five times the production capacity of the original laboratory FBE cell. The performance of these reactors compares satisfactorily with the laboratory scale cell, reported in an earlier paper [1]. The average conversion of 68-72% is slightly lower in comparison with the 75 % of the laboratory cell. The specific electric energy consumption of 9-14 kWh kg-1 of D-arabinose is slightly higher than the 7.5-11 kWh kg -1, typical of the laboratory cell.
