Abstract: This application relates to preparation of mono and bimetallic group V, VI, and VII containing carbide catalysts and the methods of using the carbide catalysts in hydroprocessing applications. A method of producing a carbide catalyst comprising: depositing a precursor metal, an acid or an amine, and an organic compound on a support thereby forming an impregnated support, wherein the organic compound has a carbon number of 10 or greater; and carbonizing the impregnated support thereby forming a carbide phase on the support.

Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Abstract: Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking activity while providing an increased activity for hydrogenation.

Abstract: The precursor of a hydroprocessing catalyst is made by impregnating a metal oxide component comprising at least one metal from Group 6 of the Periodic Table and at least one metal from Groups 8-10 of the Periodic Table with an amide formed from a first organic compound containing at least one amine group, and a second organic compound containing at least one carboxylic acid group. Following impregnation heat treatment follows to form in situ generated unsaturation additional to that in the two organic compounds. The catalyst precursor is sulfided to form an active, sulfide hydroprocessing catalyst.

Abstract: The present disclosure provides processes for hydroprocessing hydrocarbon feedstocks comprising a silicon content of about 1 wppm or greater. In at least one embodiment, a process includes introducing, in a reactor or to the reactor, a hydrocarbon feedstock having a silicon content of at least about 1 wppm, based on the total weight of the hydrocarbon feedstock, to a treat gas to produce a hydrocarbon feedstock/treat gas mixture. The process includes introducing the hydrocarbon feedstock/treat gas mixture to a catalyst composition comprising at least one group 6 metal and at least one group 8-10 metal, wherein the molar ratio of group 6 metal to group 8-10 metal is from about 10:1 to about 1:10. The process includes obtaining a liquid product comprising a sulfur content of 5,000 wppm or less. Furthermore, processes of the present disclosure provide hydroprocessing of high Si content feeds using hydrocarbon feeds at high liquid hourly space velocities.
