Process for upgrading a hydrocarbon fraction. [cracking, hydrogenating, desulfurizing, demetalating, and denitrifying]
A process is claimed for cracking, hydrogenating, desulfurizing, demetalating, and denitrifying a hydrocarbon fraction containing paraffins, olefins, olefin-equivalents, or acetylenes, as such or as substituents on ring compounds, and sulfurous, metallic and nitrogenous components: comprising cracking hydrogenating, desulfurizing, demetalating, and denitrifying said hydrocarbon fraction by contacting said hydrocarbon fraction with a water-containing fluid at a temperature in the range of from about 600/sup 0/ to about 900/sup 0/F, under super-atmospheric pressure, in the absence of externally supplied hydrogen, and in the presence of an externally supplied catalyst system containing a sulfur- and nitrogen-resistant catalyst selected from the group consisting of at least one soluble or insoluble transition metal compound and transition metal deposited on a support, said transition metal in said catalyst being selected from the group consisting of ruthenium, rhodium, iridium, osmium, and combinations thereof, wherein sufficient water is present in the water-containing fluid and said pressure is sufficiently high so that the water in the water-containing fluid has a density of at least 0.10 gram per milliliter and serves as an effective solvent for the hydrocarbon fraction, and wherein hydrogen is generated in situ; and lowering said temperature or pressure or both to thereby make the water in the water-containing fluid a less effective solvent for the hydrocarbon fraction and to thereby form separate phases, wherein essentially all the sulfur separated from the hydrocarbon fraction is in the form of elemental sulfur.
