ABSTRACT OF THE DISCLOSURE A natural active stable catalyst for use in the hydrodemetallization (HDM) and the hydroconversion (HC) of heavy crudes and residues and, in particular, a method for the preparation of the catalyst from natural clay and a process for the treatment of heavy crudes and residues with the catalyst. The catalyst is free of hydrogenating metals of Groups VIB and VIII of the Periodic Table and comprises primarily iron, silica and alumina derived from the composition of the natural clay. The catalyst possesses a surface area of between 20 to 100 m2/g, a total pore volume of between 0.20 to 0.90 cc/g, where 50 to 100% of the total pore volume contains pores of diameter greater than 400 .ANG.. The catalyst has a ratio I(Fe)/I(Si+Al) of between 0.2 to 0.9 as determined by XPS.
