ABSTRACT:
Furan concentrates containing deleterious unsaturated contaminants including sulfur compounds are purified prior to hydrogenation by contacting with zinc oxide either prior to or subsequent to separation of high boiling materials from the concentrate with the result that the furan concentrate is hydrogenated to high purity product comprising either furan and saturated materials or tetrahydrofuran and saturated materials with extended hydrogenation catalyst life. In a preferred embodiment, the furan concentrate is obtained as the by-product stream from hydrocarbon oxidative dehydrogenation processes and is subjected to distillation to remove therefrom materials boiling above about 80.degree. C prior to contacting with zinc oxide and hydrogenation.
