Beschreibung
Zusammenfassung:	The present invention relates to a method for reducing the cloud point of a Fischer-Tropsch derived fraction to below 0° C., wherein the method comprises subjecting the Fischer-Tropsch derived fraction to a cloud point reduction step comprising mixing the Fischer-Tropsch derived fraction, which comprises more than 80 wt. % of paraffins and 90 wt. % of saturates, with a solvent mixture (16), wherein the solvent mixture (16) comprises a paraffinic naphtha fraction (7) and a co-solvent (15); and subjecting the solvent treatment mixture (23) to a solvent de-waxing step (17).
