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.

Abstract:
A new composition of matter comprising molybdenum trioxide and heterocyclic nitrogen or oxygen Lewis bases. The molybdenum trioxide, upon reaction with Lewis base, forms a layered compound characterized in that the Lewis base is covalently bonded to molybdenum atoms in molybdenum oxide layers. The layered compound has the formula LMoO. sub. 3 where L is a Lewis base containing nitrogen or oxygen electron donors and selected from the group consisting of 5- and 6-membered heterocyclic amines, amine oxides, triorganophosphates, phosphine oxides and sulfoxides. L has the steric requirement such that its cross-sectional area perpendicular to an axis running through the L-Mo covalent bond is less than about 30(A). sup. 2.

Abstract:
A class of cation-reordered, bismuth-containing compounds having a perovskite-type structure of the formula Ba. sub. 2 La. sub. y Bi. sub. 2-y O. sub. 6 wherein y is greater than 0 but less than 1, is provided. Preferably, y is from 0. 25 to 0. 75, and most preferably y is 0. 5. The compositions herein are found to be particularly advantageous in the selective production of aromatic compounds from acyclic olefins, particularly in the production of benzene from propylene.

Abstract:
A new composition of matter comprising the reaction product of a mixed oxide having layers of corner linked octahedra and tetrahedra and a Lewis base. The reaction product forms a layered compound of the formula L. sub. x MOM'O. sub. 4 where MOM'O. sub. 4 is a mixed oxide selected from the group consisting of VOPO. sub. 4, VOSO. sub. 4, VOAsO. sub. 4, VOMoO. sub. 4, NbOPO. sub. 4, NbOAsO. sub. 4, TaOPO. sub. 4 and MoOPO. sub. 4, x is from about 0. 1 to 1. 0 and L is a Lewis base containing nitrogen or oxygen electron donor and is selected from the group consisting of 5-membered heterocyclic amines, 6-membered heterocyclic amines, amine oxides, triorganophosphates, phosphine oxides and sulfoxides. The layered compounds are characterized in that L is covalently bound to a metal atom in the MOM'O. sub. 4 layer.

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.
