An ultra-stable catalyst composition for hydroprocessing hydrocarbon feedstocks and a method of making and use of the ultra-stable catalyst composition. The catalyst composition of the invention comprises a calcined mixture made by calcining a formed particle of a mixture comprising an inorganic oxide material, molybdenum trioxide, and a nickel compound; wherein the calcined mixture is further overlaid with a cobalt component and a molybdenum component to thereby provide the catalyst composition.

Ultra-stable heavy hydrocarbon hydroprocessing catalyst and methods of making and use thereof

An improved process for the hydroconversion of micro carbon residue content of heavy hydrocarbon feedstocks by the use of a catalyst composition that is especially useful in the conversion of micro carbon residue of such feedstocks. The catalyst composition is a low surface area composition that further has a specifically define pore structure the combination of which provides for its enhance micro carbon residue conversion property.

Process for the catalytic conversion of micro carbon residue content of heavy hydrocarbon feedstocks and a low surface area catalyst composition for use therein

A catalyst and its use for selectively desulfurizing sulfur compounds present in an olefin-containing hydrocarbon feedstock to very low levels with minimal hydrogenation of olefins. The catalyst comprises an inorganic oxide substrate containing a nickel compound, a molybdenum compound and optionally a phosphorus compound, that is overlaid with a molybdenum compound and a cobalt compound. The catalyst is further characterized as having a bimodal pore size distribution with a large portion of its total pore volume contained in pores having a diameter less than 250 angstroms and in pores having a diameter greater than 1000 angstroms.

Catalyst and its use for the selective hydrodesulfurization of an olefin containing hydrocarbon feedstock

A hydroconversion catalyst comprising a Group VIB metal component, a Group VIII metal component and a carrier material is disclosed wherein the catalyst has a total pore volume of 0.5 to 0.9 cc/g; and a pore volume distribution such that greater than 60% of pore volume are in pores present as micropores of diameter between 55 and 115 &#x212b;, less than 0.12 cc/g of pore volume are in pores present at pores of diameter greater than 160 &#x212b; and greater than 5% of the total pore volume is in pores of diameter greater than 210 &#x212b;.

Catalyst and process for hydroconversion of a heavy feedstock

A hydroconversion catalyst comprising a Group VIB metal component, a Group VIII metal component and a carrier material is disclosed wherein said catalyst has a total surface area of 240 to 360 m/g; a total pore volume of 0.5 to 0.9 cc/g; and a pore volume distribution such that greater than 60% of pore volume are in pores present as micropores of diameter between 55 and 115 &#x212b;, less than 0.12 cc/g of pore volume are in pores present at pores of diameter greater than 160 &#x212b; and less than 10% of pore volume are in pores present as macropores of diameters greater than 250 &#x212b;.

A catalyst composition that is especially useful in the hydroconversion of pitch, micro carbon residue and sulfur contents of a heavy hydrocarbon feedstock without the excessive formation of sediment. The catalyst composition is a reasonably high surface area composition containing alumina and a low molybdenum content with a high ratio of nickel-to-molybdenum. The catalyst composition further has a unique pore distribution that in combination with the special metals loading provide for good conversion of pitch and micro carbon residue without an excessive yield of sediment.
