Abstract
A high-activity hydrotreating catalyst, having a low density, suitable for deep removal of sulfur, nitrogen, micro-carbon residue and organometallic contaminants from hydrocarbon feedstocks is disclosed. Further disclosed is a method of preparation of this catalyst, which may contain 0.3-10 wt % of a Group IVB metal promoter, 5-25 wt % of a Group VIB metal component, and 1-8 wt % of a Group VIII metal, along with a method of hydrotreating employing this catalyst.
Claims20
A method of making a hydrotreating catalyst which comprises the following steps:
- (a) mixing a refractory inorganic oxide carrier with an aqueous acidic solution comprising at least one component from Group VIII and at least one component from Group VIB to form particles of the catalyst;
- and
- (b) shaping, drying and calcining the particles of the catalyst.
A catalyst composition comprising:
- (a) a refractory organic oxide carrier;
- (b) at least one component from Group VIII;
- (c) at least one component from Group VIB;
- and
- (d) at least one component from Group IVB.
A method for the hydrotreating of a hydrocarbon feed containing a substantial amount of heteroatoms and other contaminants, which method comprises contacting said feed in a reaction zone under hydrotreating conditions comprising a temperature within the range of about 500° F. to about 850° F., a total pressure within the range of about 450 to about 3500 pounds per square inch gauge, a liquid hourly space velocity ranging from about 0.05 to about 5.0 hr.−1, and a hydrogen partial pressure ranging from about 350 to about 3200 pounds per square inch gauge, in the presence of hydrogen and with a catalyst prepared by the method comprising:
- (a) mixing a refractory inorganic oxide carrier with an aqueous acidic solution comprising at least one component from Group VIII and at least one component from Group VIB to form particles of the catalyst;
- and
- (b) shaping, drying and calcining the particles of the catalyst.
