摘要:
A hydrocarbonaceous feed, such as petroleum vacuum distillation bottoms, is upgraded by a combination coking and catalytic slurry hydroconversion process wherein a bottoms fraction from coking is passed through a microfiltration system to remove coke fines, the filtrate passed to a slurry hydroconversion zone, and the bottoms fraction from the slurry hydroconversion zone is also passed through a microfiltration system to remove catalyst particles.
摘要:
Sulfur-containing petroleum oil feedstocks which include heavy hydrocarbon constituents undergo simultaneous desulfurization and hydroconversion by contacting and reacting such feedstocks with sodamide in the presence of hydrogen and at elevated temperatures. The mixture of reaction products resulting from the above procedure is separated to give a sodium sulfur salt by-product, and a petroleum oil product which has been substantially desulfurized and demetallized, as well as being significantly improved as indicated by a reduced Conradson carbon content and an increased API gravity relative to the feedstock. Sodamide is regenerated from the sodium sulfur salt by-product and can be recycled for reaction with additional feedstock.

摘要:
Sulfur-containing petroleum oil feedstocks which include heavy hydrocarbon constituents undergo simultaneous desulfurization and hydroconversion by contacting such feedstocks with alkaline earth metal hydrides or alkaline earth metal oxides, particularly barium hydride or barium oxide, in the presence of hydrogen, and at elevated temperatures. The mixtures of reaction products resulting from the above procedure can be separated to give a petroleum oil product which has been substantially desulfurized and demetallized and significantly upgraded as demonstrated by reduced Conradson carbon content, and increased API gravity and which includes alkaline earth metal sulfide salts from which the alkaline earth metal hydrides or oxides may be regenerated.
摘要:
A heavy hydrocarbonaceous oil containing a Group IB, IVB, VB, VIB, VIIB or VIII transition metal compound is upgraded by treatment with hydrogen or a hydrogen donor compound in the presence of an aluminum alkyl compound, for example, triethyl aluminum. The transition metal compound may be naturally occurring in the oil or added to the oil. A preferred transition metal compound is vanadyl phthalocyanine.
