Benefits of technology

[0079] In some embodiments, the invention also provides, in combination with one or more of the above embodiments, a method that comprises contacting a crude feed with one or more catalysts and controlling contacting conditions to reduce a content of organic oxygen containing compounds in which: (a) a content of selected organic oxygen compounds is reduced such that the crude product has an oxygen content of at most 90% of the oxygen content of the crude feed; (b) at least one compound of the organic oxygen containing compounds comprises a metal salt of a carboxylic acid; (c) at least one compound of the organic oxygen containing compounds comprises an alkali metal salt of a ca

Problems solved by technology

Disadvantaged crudes with a relatively high TAN may contribute to corrosion of metal components during transporting and/or processing of the disadvantaged crudes.
The use of corrosion-resistant metal often involves significant expense, and thus, the use of corrosion-resistant metal in existing equipment may not be desirable.
The use of corrosion inhibitors may negatively affect equipment used to process the crudes and/or the quality of products produced from the crudes.
Disadvantaged crudes often contain relatively high levels of residue.
Such high levels of residue tend to be difficult and expensive to transport and/or process using conventional facilities.
Organically bound heteroatoms may, in some situations, have an adverse effect on catalysts.
During processing of such crudes, metal contaminants and/or compounds of metal contaminants, may deposit on a surface of the catalyst or in the void volume of the catalyst.
Such deposits may cause a decline in the activity of the catalyst.
It may be costly to regenerate the catalytic activity of a catalyst contaminated with coke.
High temperatures used during regeneration may also diminish the activity of the catalyst and/or cause the catalyst to deteriorate.
Moreover, the metals in metal salts of organic acids may cause rapid deactivation of catalysts.
Treatment facilities that process disadvantaged crudes with an oxygen content of at least 0.002 grams of oxygen per gram of disadvantaged crude may encounter problems during processing.
Organic oxygen compounds, when heated during processing, may form higher oxidation compounds (for example, ketones and/or acids formed by oxidation of alcohols, and/or acids formed by oxidation of ethers) that are difficult to remove from the treated crude and/or may corrode/contaminate equipment during processing and cause plugging in transportation lines.
When processing of hydrogen deficient hydrocarbons, consistent quantities of hydrogen generally need to be added, particularly if unsaturated fragm

Preparation of a Catalyst Support

[0278] A support was prepared by mulling 576 grams of alumina (Criterion Catalysts and Technologies LP, Michigan City, Mich., U.S.A.) with 585 grams of water and 8 grams of glacial nitric acid for 35 minutes. The resulting mulled mixture was extruded through a 1.3 Trilobe™ die plate, dried between 90-125° C., and then calcined at 918° C., which resulted in 650 grams of a calcined support with a median pore diameter of 182 Å. The calcined support was placed in a Lindberg furnace. The furnace temperature was raised to about 1000-1100° C. over 1.5 hours, and then held in this range for 2 hours to produce the support. The support included, per gram of support, 0.0003 grams of gamma alumina, 0.0008 grams of alpha alumina, 0.0208 grams of delta alumina, and 0.9781 grams of theta alumina, as determined by x-ray diffraction. The support had a surface area of 110 m2 / g and a total pore volume of 0.821 cm3 / g. The support had a pore size distribution with a med...

Preparation of a Vanadium Catalyst Having a Pore Size Distribution With a Median Pore Diameter of at Least 230 Å

[0280] The vanadium catalyst was prepared in the following manner. The alumina support, prepared by the method described in Example 1, was impregnated with a vanadium impregnation solution prepared by combining 7.69 grams of VOSO4 with 82 grams of deionized water. A pH of the solution was about 2.27.

[0281] The alumina support (100 g) was impregnated with the vanadium impregnation solution, aged for 2 hours with occasional agitation, dried at 125° C. for several hours, and then calcined at 480° C. for 2 hours. The resulting catalyst contained 0.04 grams of vanadium, per gram of catalyst, with the balance being support. The vanadium catalyst had a pore size distribution with a median pore diameter of 350 Å, a pore volume of 0.69 cm3 / g, and a surface area of 110 m2 / g. Additionally, 66.7% of the total number of pores in the pore size distribution of the vanadium catalyst had ...

Preparation of a Molybdenum Catalyst having a Pore Size Distribution with a Median Pore Diameter of at Least 230 Å

[0283] The molybdenum catalyst was prepared in the following manner. The alumina support prepared by the method described in Example 1 was impregnated with a molybdenum impregnation solution. The molybdenum impregnation solution was prepared by combining 4.26 grams of (NH4)2Mo2O7, 6.38 grams of MoO3, 1.12 grams of 30% H2O2, 0.27 grams of monoethanolamine (MEA), and 6.51 grams of deionized water to form a slurry. The slurry was heated to 65° C. until dissolution of the solids. The heated solution was cooled to room temperature. The pH of the solution was 5.36. The solution volume was adjusted to 82 mL with deionized water.

[0284] The alumina support (100 grams) was impregnated with the molybdenum impregnation solution, aged for 2 hours with occasional agitation, dried at 125° C. for several hours, and then calcined at 480° C. for 2 hours. The resulting catalyst contained ...

Abstract

Contact of a crude feed with one or more catalysts produces a total product that include a crude product. The crude feed may a total acid number of at least 0.3. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a total acid number of at most 90% of the total acid number of the crude feed. At least one of the catalysts may include one or more Column 6 metals of the Periodic Table and one or more Column 10 metals of the Periodic Table. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.
