Abstract (en)

[origin: WO9941333A1] A method for hydroisomerizing a waxy feed to favor one of VI or yield is described. The method uses a unitized pellet powder catalyst comprising a metal hydrogeneration component, a first catalytic component selected from 8, 10 and 12 ring molecular sieves and mixtures thereof, and a second amorphous isomerization component which is an amorphous inorganic oxide. Importantly, the ratio of feed and second components are present in a predetermined ratio to provide a preselected acidity favoring one of VI or yield resulting from the hydroisomerization.
