In this paper, a series of aluminum borates (AB) with various Al/B mole ratios is prepared by the precipitation method. The results indicated that the exhibited properties are dependent on the Al/B ratio of the material. The monodisperse pore size distributions of these samples simply that it is a true microcomposite structure rather than a mixture of the individual materials. Hydrodesulfurization (HDS) and hydrodemetalation (HDM) of heavy Kuwait atmospheric residuum over CoMo/AB catalysts were carried out in a bench-scale trickle bed reactor at 663 K and 7582 kPa. The weight hourly space velocity of residue oils was 1.5, and the hydrogen flow rate was kept constant at 300 mL/min (STP). The results showed that these catalysts are much more active than the conventional CoMo/Al{sub 2}O{sub 3} catalyst in HDS and HDM reactions. The results of desulfurization activity are mainly interpreted on the basis of difference in dispersion and the interaction of Mo species with the support. The demetalation activity was strongly influenced by the intraparticle diffusion of metal porphyrins.
