Abstract

A method of making highly an active mixed transition metal oxide material has been developed. The method may include sulfiding the metal oxide material to generate metal sulfides which are used as catalyst in a conversion process such as hydroprocessing. The hydroprocessing may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

First claim

The invention claimed is:

1. A method of making a mixed transition metal oxide material comprising M I , M II , M III , and M IV , where:
M I is optional and if present is a metal or mixture of metals selected from Group IB (IUPAC Group 11), Group IIB (IUPAC Group 12), Group VIIB (IUPAC Group 7), Group IIIA (IUPAC Group 13), Group IVA (IUPAC Group 14), and Group IVB (IUPAC Group 4);
M II is a metal or a mixture of metals selected from Group VIII (IUPAC Groups 8, 9, and 10);
M III is a metal selected from Group VIB (IUPAC Group 6);
M IV is a metal selected from Group VIB (IUPAC Group 6) which is different from M III ,
the material further characterized by an x-ray diffraction pattern comprising the peaks in Table A:

wherein the peak at 2θ (°) of 55-58 has a full width at half maximum larger than 3°;

the method comprising:
(a) adding sources of M II , M III , M IV , and optionally M I , to at least one quaternary ammonium hydroxide to form a slurry;
(b) reacting the slurry at a temperature from about 25° C. to about 200° C. for a period from about 30 minutes to 200 hours to generate the mixed transition metal oxide material; and
(c) recovering the mixed transition metal oxide material.

2. The method of claim 1 wherein the mixed transition metal oxide material has the formula:
(M I a ) m (M II b ) n (M III c ) o (M IV d ) p O e q
where:
M I is optional and if present is a metal or mixture of metals selected from Group IB (IUPAC Group 11), Group IIB (IUPAC Group 12), Group VIIB (IUPAC Group 7), Group IIIA (IUPAC Group 13), Group IVA (IUPAC Group 14), and Group IVB (IUPAC Group 4);
M II is a metal or a mixture of metals selected from Group VIII (IUPAC Groups 8, 9, and 10);
M III is a metal selected from Group VIB (IUPAC Group 6);
M IV is a metal selected from Group VIB (IUPAC Group 6) which is different from M III ;
a, b, c, d, and e are the valence state of M I , M II , M III , M IV , and O;

m, n, o, p, and q are the mole ratio of M I , M II , M III , M IV , and O, wherein m/(m+n)≥0 and m/(m+n)≤1, wherein (m+n)/(o+p) is from 1/10 to 10/1, wherein o/p>0, and 0≤p/o≤100, wherein q is greater than 0, and a, b, c, d, e, m, n, o, p, and q satisfy the equation:
a*m+b*n+c*o+d*p+e*q= 0.

3. The method of claim 1 wherein M I , if present, is Si, Zr, Mn, Cu, Zn, or any mixture thereof.

4. The method of claim 1 wherein M II is Fe, Co, Ni, or any mixture thereof.

5. The method of claim 1 wherein M III is Cr, Mo, or W.

6. The method of claim 1 wherein M IV is Cr, Mo, or W and is different from M III .

7. The method of claim 1 further comprising sulfiding at least a portion of the recovered mixed transition metal oxide material to form metal sulfides.

8. The method of claim 1 wherein the quaternary ammonium hydroxide is selected from tetramethylammonium hydroxide (TMAOH), tetraethylammonium hydroxide (TEAOH), tetrapropylammonium hydroxide (TPAOH), tetrabutylammonium hydroxide (TBAOH) and any combination thereof.

9. The method of claim 1 further comprising adding a binder to the reaction mixture or to the recovered mixed transition metal oxide material wherein the binder is selected from aluminas, silicas, alumina-silicas, titanias, zirconias, natural clays, synthetic clays, and mixtures thereof.

10. The method of claim 1 wherein the reacting is conducted under atmospheric pressure or autogenous pressure.

11. The method of claim 1 further comprising mixing the slurry.

12. The method of claim 1 wherein the temperature is varied during the reacting.

13. The method of claim 1 further comprising adding, to the at least one quaternary ammonium hydroxide or to the slurry, at least one short-chain alkyl quaternary ammonium halide compound having the formula [R1 R2 R3 R4-N]X, where R1, R2, R3 and R4 are alkyl groups having 1 to 6 carbon atoms, and R1, R2, R3 and R4 can be the same or different.
