Abstract: In the catalytic hydroprocessing of hydrocarbons, a hydrocarbon oil is successively contacted with a first hydroprocessing catalyst in a first reaction zone and a second hydroprocessing catalyst in a second reaction zone. The first catalyst has an average pore diameter at least about 30 angstroms larger than the second catalyst, although both have narrow pore size distributions wherein at least about 90 percent of the total pore volume is in pores of diameter from about 100 angstroms to about 300 angstroms, and with essentially all the pores having diameters greater than 100 angstroms.

Abstract: A catalyst for hydrotreating residual petroleum oil has a pore size distribution related to the measured size distribution of sulfur, nickel and vanadium containing molecules in the residual oil to be hydrotreated. The size distribution of the sulfur, nickel and vanadium containing molecules in the residual oil is measured by gel permeation chromatography. From this measured size distribution, the catalyst pore size distribution which produces desired demetalization and desulfurization is determined for specified process conditions. A catalyst having the determined pore size distribution is produced by calcining alumina at different temperatures to produce alumina with the determined pore size distribution. The alumina is impregnated with cobalt molybdenum to produce the catalyst which is tailored to produce the desired demetalization and desulfurization of the residual oil to be treated.

Abstract: A thermally stable, pure transition alumina extrudate suitable for use as a catalyst support has a uniquely defined bimodal pore size distribution and very good mechanical properties. Most of the surface area is in a micropore region having pores of less than 500 Angstrom units, a pore volume of 0.60 to 0.80 cm..sup.3 /g., a narrowly defined effective pore volume distribution within this region and a median pore diameter which can be controlled within the range of 90-210 Angstrom units. The macropore region made of pores having diameters of 1,000- 10,000 Angstrom units has a pore volume of at least 0.10 cm..sup.3 /g. These two pore volumes are essentially connected directly to each other. The extrudates can be strengthened by acidic additives and given increased thermal stability by adding rare earth oxides.

Abstract: A method for preparing an alumina having controlled pore volume distribution is disclosed. The method requires the presence of 0.1-15% by weight of a water soluble aliphatic polycarboxylic acid having from 2-12 carbon atoms based on the dry weight of Al.sub.2 O.sub.3, during alumina precipitation. The resultant calcined alumina has a pore volume distribution such that:A. Nitrogen desorption measurements indicate that less than 10% of the total pores as determined by said method fall between 100-1200A in diameter;B. Nitrogen adsorption measurements indicate that between 10-50% of the total pore volume as determined fall between 100-1200A in diameter; andC. Mercury penetration porisimetry indicates that less than 10% of the total pores as determined by both nitrogen desorption and mercury methods fall between 100-50,000A in diameter.

Abstract: A novel phospha-alumina gel having a large average pore diameter and a characteristic pore volume distribution is prepared by co-precipitation of aluminum and phosphorus compounds. The gel is then dried, formed and calcined to give a material having a large average pore diameter of at least 100 A and a characteristic pore volume distribution with a minimum number of small pores, such that less than 30% of the total pore volume is in pores smaller than 100 A in diameter. Such material is especially useful as a catalyst or as a catalyst support.
