The present invention comprises a process for removal of oxygenates from a paraffin-rich or olefin-rich paraffin stream which comprises passing a feed stream, comprising one or more C10 to C15 feed paraffins or C10 to C15 olefin-rich paraffin stream and one or more oxygenates through an adsorbent bed comprising one or more adsorbents selected from silica gel, activated alumina and sodium x zeolites to remove essentially all of said oxygenates; and recovering said paraffins. A second adsorbent bed may be employed to more thoroughly remove these oxygenates.
