ABSTRACT:
Processes and systems for removing contaminants from a paraffin containing feedstock are provided that include: providing a paraffin containing feedstock, passing the paraffin containing feedstock to an inlet of a guard bed that includes an adsorbent material, and contacting the paraffin containing feedstock with the adsorbent material in the guard bed to produce a treated paraffin containing feedstock. The processes and systems can also include removing the treated paraffin containing feedstock from an outlet of the guard bed, and passing the treated paraffin containing feedstock to a paraffin separation zone that separates normal paraffins from the treated paraffin containing feedstock.
