A process for the simultaneous desulfurization and hydroconversion of heavy carbonaceous feeds, including various sulfur-containing heavy petroleum oils, is disclosed. These feedstocks are contacted with potassium sulfide in a conversion zone maintained at elevated temperatures and in the presence of added hydrogen. In this manner, the feeds are substantially desulfurized, and significant upgrading of these feeds is also obtained as demonstrated by decreased Conradson carbon, increased API gravity, and the conversion of substantial portion of the 1,050.degree. F.+ portion of these feeds. In a preferred embodiment, such a process is disclosed employing a combination of potassium sulfide and sodium sulfide, and in particular these processes include procedures for the regeneration of the sulfides and their recycle to the conversion zone.
摘要:
A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 wt. % platinum group metal, about 0.5 to about 5 wt. % cobalt, about 0.01 to about 5 wt. % germanium and about 0.1 to about 3.5 wt. % halogen, wherein the platinum group metal, cobalt and germanium are uniformly dispersed throughout the porous carrier material, wherein substantially all of the platinum group metal is present in the elemental metallic state, wherein substantially all of the germanium is present in an oxidation state above that of the elemental metal, and wherein substantially all of the cobalt is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions or in a mixture of these states, in which process there is effected a chemical consumption of hydrogen. A specific example of one such catalyst is a composite of a crystalline aluminosilicate, a platinum group metal component, a cobalt component, a germanium component, and a halogen component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogeneration of aromatic nuclei, the ring-opening of cyclic hydrocarbons, hydrogenation, etc.

A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite of a porous carrier material, a platinum or palladium component, a rhodium component and a tin component, in which process there is effected a chemical consumption of hydrogen. A specific example of one such catalyst is a composite of a crystalline aluminosilicate, a platinum component, a rhodium component and a tin component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogenation of aromatic nuclei, the ring-opening of cyclic hydrocarbons, desulfurization, denitrification, hydrogenation, etc.
摘要:
A process for hydrocracking petroleum fractions to produce lubricating oils of suitable viscosity index comprising subjecting a petroleum fraction to hydrocracking conditions selected to minimize the formation of non-lube oil fractions in the presence of a first hydrocracking catalyst, fractionating the resulting hydrocracked lube oil stock into a plurality of fractions having different boiling ranges, subjecting a higher boiling fraction to hydrocracking conditions in the presence of a second hydrocracking catalyst and blending the resulting lube oil fractions to produce the lube oil base stocks of the desired viscosity and viscosity index.
摘要:
A method for removing a contaminant comprising at least one of arsenic and selenium from a synthetic crude oil or fraction thereof characterized by a multi-step process as follows. First, a guard bed is prepared from a plurality of particles of material that is either iron, cobalt, nickel, oxides or sulfides of these metals, or a mixture thereof. Next, the synthetic crude oil is admixed with hydrogen and flowed past the particles of material at a temperature and pressure great enough and with a residence time sufficient to allow the contaminant to be removed from the synthetic crude and be deposited on at least the surface layer of the particles of material. As the surface layer of the particles becomes substantially saturated with the contaminant, they are removed from the surface of the particles as small fines, entrained in the fluid stream and flowed from the guard bed. The small fines having the contaminant thereon are separated from the synthetic crude from which the contaminant has been removed. Thereafter, the synthetic crude oil is treated as desired. Also disclosed are specific methods of effecting the removal and separation of the contaminant and the fines; including specific and preferred process details.
