ABSTRACT:
Catalyst shapes for inorganic oxide, hydroprocessing catalysts are disclosed. When the catalyst is used for diffusion limited reactions, and particularly when it is used for demetalation, shaped catalysts give longer catalyst lifetimes. Preferred shapes include fluted trilobal, asymmetric quadralobal and elongated quadralobal.
