Abstract

The present invention has for its object a process of deasphaltizing and deparaffining applicable to mixtures of hydrocarbons such as crude mineral oils and tars obtained under the influence of heat from shales, lignites, peats, and similar products, to natural bitumens and those obtained by extraction with organic solvents and also all those derived from the substances, the process in question having the following characteristics: the coagulation or the precipitation of the asphaltic material, the resinous material, and the asphaltic and resinous material, which is found in the colloidal state or any other state in the substances given above, is obtained by the addition of a small amount of solvent and of acids or mixtures of acids.
