Abstract:
The present invention is directed to an improved finished hydroisomerization catalyst manufactured from a first high nanopore volume (HNPV) alumina having a broad pore size distribution (BPSD), and a second HNPV alumina having narrow pore size distribution (NPSD). Their combination yields a HNPV base extrudate having larger porosity with a bimodal pore size distribution as compared to a conventional base extrudates.
