| abstract | PROCESS FOR PURIFYING HYDROCARBONACEOUS OILS ABSTRACT OF THE DISCLOSURE A process for purifying hydrocarbonaceous oils containing heteroatom sulfur and heteroatom nitrogen compound impurities comprising the steps of: (1) reacting said hydrocarbonaceous oil with an oxidizing gas containing at least one nitro-gen oxide with more than one oxygen atom for each nitrogen atom while maintaining (a) the molar ratio of the nitrogen oxide to the total of the sulfur heteroatom content and the nitrogen heteroatom content to about 1.5:1 or less, (b) the reaction time to about one hour or less, (c) the temperature to about 100°C or less, and (d) a conversion of sulfur heteroatom content into gaseous sulfur oxides to about 60% or less on a weight basis; (2) contacting the oil from step (1) above with (i) an extracting solvent comprising at least one amine selected from the group consisting of ethylene diamine, mono-ethanolamine, diethanolamine and mixtures thereof, or a water mixture thereof containing about 50% by weight or less water, and (ii) an extracting solvent comprising formic acid or a water mixture thereof con-taining about 50% by weight or less water, with the contacting with (i) and (ii) being sequential and in any order; and (3) separating said oil from step (2) above from the extracting solvents; to recover purified hydrocarbonaceous oil. |
