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.
