  • Catalyst and process for hydroconversion of a heavy feedstock
    Patent number: 10118161
    Abstract: 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 ?, less than 0.12 cc/g of pore volume are in pores present at pores of diameter greater than 160 ? and greater than 5% of the total pore volume is in pores of diameter greater than 210 ?.

  • High surface area composition for use in the catalytic hydroconversion of a heavy hydrocarbon feedstock, a method making such composition and its use
    Patent number: 9039891
    Abstract: 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.
