A naphtha or a middle distillate hydrocarbon is hydrodenitrogenized by hydrotreating in the presence of a catalyst containing a carbon support bearing (i) molybdenum or tungsten, (ii) a metal of non-noble Group VIII, and (iii) chromium.

Hydrodenitrogenation of hydrocarbons utilizing a carbon-supported

A naphtha or a middle distillate hydrocarbon is dehydroaromatized by hydrotreating in the presence of a catalyst containing non-noble Group VIII metal and Group VI-B metal on carbon.

Carbon-supported hydrodearomatization catalyst

A naphtha or a middle distillate hydrocarbon is hydrodearomatized by hydrotreating in the presence of a catalyst containing a carbon support bearing (i) molybdenum or tungsten, (ii) a metal or non-noble Group VIII, and (iii) chromium.

Hydrodearomatization of Hydrocarbons

Hydrodearomatization catalyst composition

A naphtha or a middle distillate hydrocarbon is hydrodearomatized by hydrotreating in the presence of a catalyst containing boron, non-noble Group VIII metal, and Group VIB metal on a carbon support.

Hydrodearomatization of hydrocarbons

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 method of selectively hydrodenitrogenating various raw hydrocarbon oils such as various petroleum feedstocks, coal liquids, shale oils and sand oils, which method comprises passing the raw hydrocarbon oil along with hydrogen (H.sub.2) over sulfided carbon supported Fe-Mo catalysts, whereby the raw hydrocarbon oil is hydrodenitrogenated with a selectivity significantly higher than that is possible with conventional alumina supported hydrotreating catalysts.

Method for selective hydrodenitrogenation of raw oils

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

Hydrodearomatization of middle distillate hydrocarbons

A method of selectively hydrodenitrogenating various raw hydrocarbon oils such as various petroleum feedstocks, coal liquids, shale oils and sand oils, which method comprises passing the raw hydrocarbon oil along with hydrogen (H.sub.2) over sulfided carbon supported Fe--Mo catalysts, whereby the raw hydrocarbon oil is hydrodenitrogenated with a selectivity significantly higher than that is possible with conventional alumina supported hydrotreating catalysts.
