Abstract

Methods for conversion of a hydrocarbon feed to a total product are described. Contact of the hydrocarbon feed with one or more catalysts at controlled contacting conditions produces the total product. The total product includes a crude product that is a liquid mixture at 25° C. and 0.101 MPa and has a basic nitrogen content of at most 90% of the basic nitrogen content of the hydrocarbon feed.

Claims

1. A method of producing a crude product, comprising:

contacting a hydrocarbon feed with one or more catalysts to produce a total product that includes the crude product, wherein the crude product is a liquid mixture at 25°

C. and 0.101 MPa, the hydrocarbon feed having a basic nitrogen content of at least 0.0001 grams per gram of hydrocarbon feed, at least one of the catalysts has at least 0.01 grams of one or more metals from Column 6 of the Periodic Table and/or one or more compounds of one or more metals from Column 6 of the Periodic Table per gram of catalyst, the Column 6 metal catalyst having a pore size distribution with median pore diameter of between 50 angstroms and 180 angstroms;

controlling contacting conditions at a pressure of at least 3 MPa and a temperature of at least 300°

C. to produce the crude product, the crude product having a basic nitrogen content of at most 90% of the basic nitrogen content of the hydrocarbon feed and wherein basic nitrogen is as determined by ASTM Method D2896.

2. The method of claim 1, wherein the Column 6 metal catalyst comprises molybdenum.

3. The method of claim 1, wherein the Column 6 metal catalyst comprises at most 0.1 grams of molybdenum per gram of catalyst.

4. The method of claim 1, wherein the Column 6 metal catalyst is a supported catalyst, and wherein the support comprises alumina, silica, silica-alumina, titanium oxide, zirconium oxide, magnesium oxide, or mixtures thereof.

5. The method of claim 1, wherein the Column 6 metal catalyst has a pore size distribution with a median pore diameter from 55 angstroms to 150 angstroms, from 60 angstroms to 135 angstroms, or from 70 angstroms to 120 angstroms.

6. The method of claim 1, wherein the Column 6 metal catalyst has a surface area of at least 200 m²/g.

7. The method of claim 1, wherein the Column 6 metal catalyst comprises molybdenum, nickel, cobalt or mixtures thereof.

8. The method of claim 1, wherein the Column 6 metal catalyst further comprises one or more elements from Column 15 of the Periodic Table and/or one or more compounds of one or more elements from Column 15 of the Periodic Table.

9. The method of claim 1, wherein the hydrocarbon feed has an API gravity of at most 10.

10. The method of claim 1, wherein the crude product has an increase in API gravity of at least 5 relative to the API gravity of the hydrocarbon feed.

11. The method of claim 1, wherein the hydrocarbon feed has at least 0.01 grams of C₅ asphaltenes per gram of hydrocarbon feed, and wherein the crude product has a C₅ asphaltenes content of at most 90% of the hydrocarbon feed C₅ asphaltenes content.

12. The method of claim 1, wherein the hydrocarbon feed has a MCR content of at least 0.002 grams of MCR per gram of crude, and wherein the crude product has an MCR content of at most 90% of the MCR content of the hydrocarbon feed MCR content.

13. The method of claim 1, wherein the hydrocarbon feed has a viscosity of at least 10 cSt at 37.8°

C., and wherein the crude product has a viscosity at 37.8°

C. of at most 50% of the viscosity of the hydrocarbon feed at 37.8°

C.

14. The method of claim 1, wherein the crude product has a residue content of at most 80%, at most 70%, or at most 60% of the hydrocarbon feed residue content.

15. The method of claim 1, wherein the hydrocarbon feed is contacted with one or more catalysts in a fixed bed reactor.

16. The method of claim 1, further comprising heating the one or more catalysts to a temperature of at least 400°

C. in a time period of less than three weeks.

17. The method of claim 16, wherein the one or more catalysts are heated prior to contacting the hydrocarbon feed with the one or more catalysts.
