Abstract: A method of upgrading refining streams with high polynucleararomatic hydrocarbon (PNA) concentrations can include: hydrocracking a PNA feed in the presence of a catalyst and hydrogen at 380° C. to 430° C., 2500 psig or greater, and 0.1 hr−1 to 5 hr−1 liquid hourly space velocity (LSHV), wherein the weight ratio of PNA feed to hydrogen is 30:1 to 10:1, wherein the PNA feed comprises 25 wt % or less of hydrocarbons having a boiling point of 700° F. (371° C.) or less and having an aromatic content of 50 wt % or greater to form a product comprising 50 wt % or greater of the hydrocarbons having a boiling point of 700° F. (371° C.) or less and having an aromatic content of 20 wt % or less.

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.
