METHOD OF REMOVING OXYGENATES FROM STREAM OF PARAFFINS Russian patent published in 2011 - IPC C07C7/12 C07C9/14 C07C11/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of removing oxygenate from a stream containing 50-99.99 wt % paraffins and 0-50 wt % olefins, which involves the following steps: a) passing a supply stream containing 50-99.99 wt % of one or more starting C₁₀-C₁₅-paraffins, 0-50 wt % olefins and one or more oxygenates through an adsorbent layer which is an exchange alkali or alkali-earth cation of zeolite X in order to remove virtually all said oxygenates; and b) removing paraffin(s) from the adsorbent layer to obtain a clean stream.

EFFECT: use of present method enables to remove a wide range of oxygenates from raw materials, a large portion of which contains C₁₀-C₁₅-paraffins.
