Abstract
A method of treating or refining a wax includes hydrogenating a feed wax which has an MEK-solubility oils content of more 0.5 weight % to provide a hydrogenated wax. Thereafter the hydrogenated wax is de-oiled to reduce the MEK-solubility oils content of the hydrogenated wax, producing a refined wax or a wax product.
