US Patent:

48015709, Jan 31, 1989

Filed:

Jan 29, 1987

Appl. No.:

7/008008

Inventors:

Archie R. Young - Montclair NJ
Teh C. Ho - Bridgewater NJ
Allan J. Jacobson - Princeton NJ
Russell R. Chianelli - Somerville NJ

Assignee:

Exxon Research and Engineering Company - Florham Park NJ

International Classification:

B01J 27047
B01J 27049
B01J 27051

US Classification:

502220

Abstract:

This invention relates to the preparation and use of supported, manganese sulfide promoted molybdenum and tungsten sulfide catalysts useful for hydroprocessing processes, particularly hydrotreating. These catalysts are prepared by heating a composite of support material and precursor salt under oxygen-free conditions and in the presence of sulfur, wherein said precursor salt contains a thiometallate anion of Mo, W or mixture thereof and a cation comprising one or more promoter metals which are chelated by at least one neutral, nitrogen-containing polydentate ligand, and wherein said promoter metal comprises Mn alone or a mixture of Mn with Co, Ni, Zn, Cu or mixture thereof.

B01J 3118

US Classification:

502220

Abstract:

Supported hydroprocessing catalysts comprising a sulfide of trivalent chromium and Mo, W or mixture thereof are obtained by compositing a preselected quantity of support material with a precursor comprising a mixture of (i) a hydrated oxide of trivalent chromium and (ii) a salt containing a thiometallate anion of Mo or W and a cation comprising the conjugate acid of at least one neutral, nitrogen-containing polydentate ligand and heating the composite in the presence of sulfur and hydrogen in an oxygen-free atmosphere. These compositions have been found to be useful hydrotreating catalysts having nitrogen removal activity superior to that of commercial catalysts derived from cobalt molybdate on alumina.
