  • Publication number: 20020112987
    Abstract: A slurry hydroprocessing process (SHP) where a hydrocarbon feedstock is treated at slurry hydrotreating conditions, in the presence of a hydrogen containing treat gas and in the presence of a supported metallic catalyst which is a supported sulfide of a metal selected from the group of non-noble Group VIII metals, Group VIB metals and mixtures thereof where the support is an inorganic oxide and where the catalyst has an average diameter of about 0.5 to about 100 microns to obtain a first product stream comprising the catalyst and a hydroprocessed feedstream; separating the first product into a catalyst-free product stream and a catalyst-containing stream and recycling at least a portion of the catalyst-containing stream back to the hydroprocessing step.

  • Publication number: 20020005374
    Abstract: A process for upgrading a feedstream, said process comprising: (a) solvent deasphalting, under solvent deasphalting conditions, said feedstream to obtain a first product stream comprising deasphalted oil and a second product stream comprising asphalt product; (b) slurry hydroprocessing said asphalt product in a slurry hydroprocessing unit under slurry hydroprocessing conditions to obtain a hydroprocessed product; and (c) separating an upgraded oil from the hydroprocessed product and unconverted asphaltene bottoms.

  • Patent number: 6258258
    Abstract: The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.

  • Patent number: 5928502
    Abstract: The invention comprises a method for reducing the amount of carboxylic acids in petroleum feeds comprising the steps of (a) adding to said petroleum feed a catalytic agent comprising an oil soluble or oil dispersible compound of a metal selected from the group consisting of Group VB, VIB, VIIB and VIII metals, wherein the amount of metal in said petroleum feed is at least about 5 wppm, (b) heating said petroleum feed with said catalytic agent in a reactor at a temperature of about 400 to about 800.degree. F. (about 204.44 to about 426.67.degree. C.) and a pressure of about atmospheric to about 1000 psig (about 6996.33 kPa) in the substantial absence of hydrogen, and (c) sweeping the reactor containing said petroleum feed and said catalytic agent with an inert gas to maintain the combined water and carbon dioxide partial pressure below about 50 psia (344.75 kPa).

  • Patent number: 5891325
    Abstract: The instant invention is directed to a process for reducing organic acids in petroleum feeds containing organic acids comprising: (a) thermally treating a petroleum feed containing organic acids in a thermal reaction zone comprising a plurality of stages in series, at a temperature and pressure sufficient to decompose at least a portion of said organic acids while sweeping said plurality of stages with an inert gas, to produce a volatile organic acid containing hydrocarbon fraction and a non-volatile hydrocarbon fraction; (b) treating said volatile hydrocarbon fraction to neutralize at least a portion of said organic acids therein and to produce a treated volatile hydrocarbon fraction; (c) collecting said non-volatile hydrocarbon fraction from said thermal reaction zone; and (d) blending said treated volatile hydrocarbon fraction of step (b) with said collected non-volatile hydrocarbon fraction.

  • Patent number: 5879529
    Abstract: The present invention provides for a method of decreasing the Conradson carbon content of metal containing petroleum streams by forming a mixture of the Conradson carbon containing petroleum fraction and an aqueous electrolysis medium containing an electron transfer agent, and passing an electric current through the mixture or optionally through the pretreated aqueous electrolysis medium at a voltage, sufficient to decrease the Concarbon content of the stream. The cathodic voltage is from 0 V to -3.0 V vs. SCE. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries.

  • Patent number: 5855764
    Abstract: The present invention provides for a method of decreasing the metals content of metal containing petroleum streams by forming a mixture of the petroleum fraction containing those metals and an aqueous electrolysis medium containing electron transfer agent, and passing an electric current through the mixture or through the pretreated aqueous electrolysis medium at a voltage, sufficient to remove the metals such as Ni, V and Fe from the stream (i.e. to produce a petroleum fraction having decreased content of the metals). The cathodic voltage is from 0 V to -3.0 V vs. SCE. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their metals, e.g., Ni and V content.
