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.

An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.

The present disclosure generally relates to methods for deoiling a hydrocarbon feed and to products formed therefrom. In an embodiment is provided a method of deoiling a feed that includes introducing a waxy feed and a deoiling solvent to a dilution chilling zone; mixing the waxy feed and the deoiling solvent in the dilution chilling zone at a temperature of from about 10 F. to about 30 F. to form a slurry; introducing the slurry to a filter zone, the filter zone comprising one or more filter stages, wherein a temperature of the slurry is from about 40 F. to about 75 F.; separating the wax from the oil and the deoiling solvent to form a wax cake in a first filter stage; and washing the wax cake in the first filter stage with the deoiling solvent to obtain a composition comprising a wax. In another embodiment is provided a composition comprising a wax.
