Abstract
A hydroprocessing catalyst is provided that is supported hydrotreating catalyst, where the shaped support of 0.36-0.46 void fraction is comprised of a single source of gamma alumina with a medium pore diameter of 10 nm and at least 0.95 cc/g pore volume but not more than 1.10 cc/g, and includes a single, Group IIIb metal dispersed by mulling or mixing in a forming step, and a surface area by nitrogen BET between about 230 m2/g and 260 m2/g, and where the finished catalyst can be described in terms of molar ratios relative to aluminum, where the aluminum concentration may vary from 26 to 30 wt %, Al: Group VIb 4.8-5.6, Al: Group VIII 14.9-19.0, Al: Group Va 9.6-12.7, and Al: Group IIIb 112.5-228.2.
Claims18
A supported hydroprocessing catalyst comprising a shaped support having a void fraction of about 0.36 to 0.46, and a surface area by nitrogen BET between about 230 m2/g and 260 m2/g, 90-200 Angstroms median pore diameter, and at least 0.95 cc/g but not more than 1.10 cc/g pore volume wherein the supported hydroprocessing catalyst comprises about 26 to 30 wt % aluminum.
A process of making a hydroprocessing catalyst comprising dispersing a Group 3 metal by mulling or mixing in a single forming step and adding Group VIb, Group VIII and Group Va elements to a gamma alumina support in a single step.
