Abstract
There is provided a catalyst comprising at least one hydrogenation metal, such as Ni and Mo, supported on a delaminated layered silicate, such as kenyaite, which has been swollen and calcined. There is also provided a method for making this catalyst. There is further provided a process for using this catalyst to demetalize a petroleum feedstock, such as a gas oil.
Claims8
A method for making a catalyst, said catalyst comprising at least one hydrogenation metal supported on a delaminated layered silicate lacking octahedrally coordinated sheets of clays, said method comprising the steps of:
- (i) contacting said layered silicate with a swelling agent under conditions sufficient to incorporate said swelling agent into the interspathic region of said layered silicate and to separate the layers of said layered silicate;
- (ii) calcining the swollen layered silicate of step (i) under conditions sufficient to delaminate the layers of said layered silicate;
- and
- (iii) combining the layered silicate of step (ii) with at least one hydrogenation metal.
