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.
