Embodiment Construction

[0012] The petrolatum hydrorefining method of the present invention can use a single vacuum residue light dewaxing paste or its blend as the petrolatum hydrorefining raw material. The components that can be blended with the vacuum residue light dewaxing paste include vacuum distillate base oil, vacuum distillate dewaxing oil and solvent refined oil.

[0013] The petrolatum hydrorefining method of the present invention adopts two fixed-bed reactors, or one reactor is connected in series with two catalyst beds. The catalyst can be any petroleum wax product hydrorefining catalyst, including W-Ni Type hydrorefining catalyst and Mo-Ni type hydrorefining catalyst. The two reactors can be filled with the same catalyst or different catalysts.

[0014] Different raw materials and catalysts generally need to draw different product penetration curves corresponding to the temperature of the first reactor, but the curves obtained from typical raw materials and catalysts are representative and ...

Abstract

This invention opens one manufacturing method of geoline of different consistencies, especially one hydrofining method to produce geoline of different consistencies, with single component short residue cerate or its concoction as the materials. Characteristics of this method is that pricking degrees of hydrogenation materials can be changed by suitable degradation reaction. Any hydrofining catalyst of petroleum wax can be used in this method. This method solves the problem existing in current techology that different features of materials have to be prepared to produce geoline of different consistencies and can be flexibly and conveniently applied to produce products of different consistencies. Geoline produced by this method can be applied in medicine and cosmetics.

Description

Technical field [0001] The present invention relates to a method for producing petrolatum, in particular to a method for producing petrolatum by hydrogenating and refining a single-component vacuum residue light dewaxing paste or its blend as a raw material for petrolatum, in particular to a method that can obtain various consistency Flexible production methods for petroleum jelly products. Background technique [0002] Vaseline is an ointment-like petroleum product with certain characteristics. The conventional petroleum jelly production process is to first blend the raw materials, and then refine the blend. The traditional Vaseline blending components are vacuum distillate base oil and vacuum residue light dewaxing paste. The hydrogenation method can effectively remove the sulfur, nitrogen, oxygen and other heterocyclic substances in the petroleum jelly raw materials, and saturate the fused ring aromatics. The method has no three wastes pollution during the production process, ...
