ABSTRACT:
A process for improving the color of oxygenates, such as MTBE, ETBE and TAME, which utilizes a hydrogenation treater in the presence of a catalyst, containing at least one noble metal, along with a circulation of hydrogen to remove the color. The process reduces existing color bodies in the oxygenate and may proceed at room temperature and at normal pressure for economically providing a completely clear product having a +30 saybolt number.
