摘要： Catalysts for hydroconversion of heavy oils, particularly those containing Ramsbottom carbon precursors, comprise nickel or cobalt and molybdenum on porous alumina containing 1-3% silica. The catalysts have total pore volume of 0.5 to 1.5 ml/gm with at least 70% of the pore volume in pores of 40-60.ANG. pore radius and with only about 10-35% of the nickel or cobalt in acid extractable form.

摘要： Spherical particles of alumina are prepared by agitating a slurry of solids comprising rehydratable alumina solids in water with a hot immiscible liquid to disperse droplets of the slurry in a continuous phase of the immiscible liquid. The droplets are shaped by interfacial surface tension and are hardened by heat while in the immiscible liquid, then are separated and calcined to produce finished spherical alumina beads. The preferred beads are of size less than one millimeter. These are used as supports for catalysts that are used in several oil refining processes such as hydrotreating for removal of sulfur or for reforming or cracking.
