A column reactor operating at 68 +/- 2C was used to demonstrate the feasibility of a new process that simultaneously dehydrates ethanol and extracts crude oil from dried ground corn. For each kilogram of dried corn, the moisture absorption capacity was approximately 32 g using 95% (w/w) ethanol as solvent. As a result, it was possible to dehydrate 500 ml of 95% ethanol and simultaneously extract 45 g of the crude oil from each kilogram of dried ground corn. The crude oil contained 2.1% of phospholipids on a dry weight basis.
