Abstract
The present invention is directed to an improved finished hydroisomerization catalyst manufactured from a first high nanopore volume (HNPV) alumina and a pore size distribution characterized by a full width at half-maximum, normalized to pore volume, of 15 to 25 nm·g/cc, and a second HNPV alumina having a pore size distribution characterized by a full width at half-maximum, normalized to pore volume, of 5 to 15 nm·g/cc. Their combination yields a HNPV base extrudate having a low particle density as compared to a conventional base extrudates.
