ABSTRACT:
A process for preparing motor fuel grade alcohol wherein an ethanol fermentation reactor effluent is distilled to produce an overhead product comprising 10 to about 40 mole percent ethanol and a bottom product comprising the non-alcoholic components. The motor fuel grade alcohol is recovered in high yield from the ethanol/water overhead product mixture in a liquid phase cyclic selective adsorption process which comprises a plurality of adsorption columns operated in cycle in a predetermined time sequence, each adsorption column containing an adsorbent, wherein each respective adsorption column undergoes successive steps of adsorption, desorption and rinsing.
