A hydrocarbon feedstock is brought into contact with activated carbon at a temperature of about 300.degree. to about 650.degree. C. and a pressure of about 0-1000 psig in the absence of added hydrogen to reduce the content of aromatic, sulfur and nitrogen compounds contained therein and to simultaneously lower the specific gravity thereof.

Catalytic hydrocarbon upgrading process requiring no external hydrogen

A sulfided carbon support catalyst bearing (i) a non-noble Group VIII metal, (ii) a Group VI-B metal, and (iii) a metal of Group IA, II A, III-B, or the lanthanide Group of rare earths.

Hydrotreating of cracked naphtha

Disclosed is a phosphorus treated activated carbon composition suitable for use as catalyst support, catalyst, and an adsorbent, which is produced by treating (e.g., by mixing or impregnating) an activated carbon material having a surface area greater than 100 m.sup.2 /g with a phosphorus-containing compound, drying, and heating to a temperature of from 450.degree. C. to about 1200.degree. C., wherein the resulting composition is characterized by a phosphorus compound combined with the carbon in the amount of from above 2.5% to about 10% phosphorus, based on the weight of the composition.

Phosphorus-treated activated carbon composition

A process for simultaneous hydrodearomatization, hydrodesulfurization and hydrodenitrogenation of a charge hydrocarbon oil containing undesired aromatic components, sulfur and nitrogen compounds, which comprises: maintaining a bed of a sulfided metal catalyst comprising one or more metals of non-noble Group VIII, at least one metal selected from tungsten and molybdenum on a novel 'phosphorus treated carbon' support, the 'phosphorus treated carbon' support being comprised of phosphorus bound to the carbon surface predominantly as polyphosphate species characterized by peaks between -5 and -30 ppm in the solid-state magic angle spinning .sup.31 p nuclear magnetic resonance spectrum; passing a charge hydrocarbon feed in the presence of hydrogen into contact with said catalyst at hydrotreating conditions, thereby effecting hydrodearomatization, and simultaneously effecting hydrodesulfurization and hydrodenitrogenation.

Hydrodearomatization of hydrocarbon oils using novel 'phophorus treated

A process for treating a charge hydrocarbon oil containing undesired aromatic components, sulfur and nitrogen compounds, which comprises maintaining a bed of a sulfided catalyst comprising 0.1 to 15% by weight of nickel; and from 1 to 50% by weight of tungsten and 0.01 to 10% by weight of phosphorus, on an activated carbon support, and passing a charge hydrocarbon feed in the presence of hydrogen into contact with said catalyst at hydrotreating conditions, thereby effecting hydrodearomatization, hydrodesulfurization and hydrodenitrogenation of said charge hydrocarbon feed containing undesired aromatic components, sulfur and nitrogen, and forming a product stream of hydrocarbon containing a lesser quantity of undesired aromatic components, sulfur and nitrogen; and recovering said product stream of hydrocarbon containing a lesser quantity of undesired aromatic components, sulfur and nitrogen.

Process for hydrodearomatization of hydrocarbon oils using carbon

A process for simultaneous hydrodearomatization, hydrodesulfurization and hydrodenitrogenation of a charge hydrocarbon oil containing undesired aromatic components, sulfur and nitrogen compounds, which comprises:

Hydrodearomatization of hydrocarbon oils using novel 'phosphorus treated

Hydrodesulfurization of cracked naphtha, with minimum attendant hydrogenation of olefins, is effected over a sulfided carbon support catalyst bearing (i) a non-noble Group VIII metal, (ii) a Group VI-B metal, and (iii) a metal of Group IA, II A, III B, or the lanthanide Group of rare earths.

A method of catalytically hydroconverting a hydrocarbon feed stream containing a substantial quantity of components boiling above about 1000.degree. F. to convert a substantial portion thereof to components boiling below 1000.degree. F. is disclosed. More particularly, aromatic heavy oil additive, such as Heavy Cycle Gas Oil, is added to a heavy hydrocarbon feed stream and the stream is contacted with a solid catalyst and an oil-miscible metal naphthenate. The method disclosed herein advantageously substantially eliminates plugging of the hydroconversion reactor and minimizes the amount of insolubles in the total liquid product.

Hydroprocessing of heavy hydrocarbonaceous feeds

A waste molybdenum-containing stream recovered from the work-up of a reaction mixture wherein propylene has reacted with t-butyl hydroperoxide to form propylene oxide (in the presence of a complex of ethylene glycol and a molybdenum compound) is passed as an oil-miscible/soluble molybdenum-containing catalyst to a reaction wherein heavy hydrocarbon is hydroconverted to lower boiling products in the presence of heterogeneous catalyst.
