27 ABSTRACT OF THE DISCLOSURE An amphora-type particulate catalyst-support having an adequately small average particle size and a low attrition index and a method for preparing an amphora-type particulate catalyst-support are disclosed, wherein the method comprises the steps of: (a) forming a mixed slurry having a solid content of 10 to 30 wt% by adding water to a mixture of 60 to 80 parts by weight of a component (A) comprising at least one component selected from the group consisting of allophane, red mud, bauxite, and laterite with 20 to 40 parts by weight of a binder (B), such as silica sol, alumina-titania, etc.,; (b) wet grinding the solid in the mixed slurry to form a slurry of finely divided solid having an average particle size of 0.6 to 2.0 µ m; (c) spray-drying the slurry of the finely divided solid to form spray-dried particles; and (d) calcining the spray-dried particles. The catalyst-supports can be advantageously used as a support for preparing particulated catalysts having improved properties; i.g., high catalytic activities and selectivities, a high anti-attrition property, etc., especially those which are very effective for the hydrotreating of a heavy oil, such as a vacuum reside, etc., giving a high yield of a kerosine-light oil fraction 28 with a low hydrogen consumption and low yields of by- products, such as cokes, asphaltenes, and the like.
