Abstract
The invention relates to a spherical catalyst composition comprising a Group VI metal component and optionally a Group VIII metal component on a carrier, which catalyst has a particle size of 0.5-7 mm, a total pore volume of 0.5-1.3 ml/g, an average pore diameter of 15-30 nm, and a % PV(>100 nm) of 2-30%, there being substantially no difference in density between the core region of the carrier particles and their surface regions. The catalyst is particularly suitable for use in non-fixed bed processes for the hydroprocessing of heavy hydrocarbon feeds. It has high hydrodesulfurization and hydrodemetallization activity in combination with a high abrasion resistance.
