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.

Hydroprocessing scheme for production of premium isomerized light

A process for preparing a metallosilicate catalyst includes the steps of: forming a mixture of at least one non-alkali metal, a templating agent, and an organic base; adding a silicon additive to the mixture so as to form a metallosilicate hydrogel; aging the hydrogel to obtain a crystalline metallosilicate composition; washing and drying the crystalline composition; and calcining the crystalline composition so as to provide a metallosilicate catalyst. Two or more non-alkali metals may be selected so as to provide a multifunctional catalyst.
