Abstract
A hydroconversion catalyst composition includes a catalytically active matrix having a surface area of between about 50 m.sup.2 /g to about 290 m.sup.2 /g, a silicious molecular sieve support medium distributed through the matrix and having a surface area of between about 250 m.sup.2 /g to about 1200 m.sup.2 /g and a catalytically active phase supported on the support medium and including a first metal selected from group IIIA of the periodic table of elements and a second metal selected from group VIB of the periodic table of elements. The matrix preferably further includes aluminum, gallium, cobalt, molybdenum, and phosphorus.
Claims43
A hydroconversion catalyst system, comprising:
- a catalytically active matrix;
- a support medium distributed through the matrix and comprising a silicious molecular sieve material;
- and
- a catalytically active phase supported on the support medium and comprising a first metal selected from group IIIA of the periodic table of elements and a second metal selected from group VIB of the periodic table of elements.
A hydroconversion catalyst system comprising:
- a catalytically active matrix comprising a first metal selected from group IIIA of the periodic table of elements, a second metal selected from group IIIA, a third metal selected from group VII, a fourth metal selected from group VIB, and a fifth metal selected from group VA;
- a support medium distributed through the matrix and comprising a silicious molecular sieve material;
- and
- a catalytically active phase supported on the support media and comprising a group IIIA metal and a group VIB metal.
A process for preparing a hydroconversion catalyst system, comprising the steps of:
- providing a support medium comprising a silicious molecular sieve material having a surface area of between about 250 m.sup.2 /g to about 1200 m.sup.2 /g and supporting a catalytically active phase comprising a first metal selected from group IIIA of the periodic table of elements and a second metal selected from group VIB of the periodic table of elements;
- providing a matrix material having a surface area of between about 50 m.sup.2 /g to about 290 m.sup.2 /g;
- mixing said support medium with said matrix to form a substantially homogeneous paste having a ratio by weight of said support medium to said matrix of at least about 0.1;
- forming said paste into catalyst elements;
- and
- calcining said catalyst elements whereby at least a portion of said first metal of said catalytically active phase migrates from said support medium to said matrix whereby said matrix is catalytically active.
