| Abstract: | A stirred catalytic basket reactor with immobilized yeast cells was used for the batchwise production of ethanol. Fractional conversions up to 0.99 in 10 h were attained, depending on the agitation rates, initial glucose, and cell densities. The volumetric productivity of the reactor was considerably better than that of conventional stirred tank reactors. Productivities were strongly dependent on the stirred speed. |
