Abstract:
1. A hydrotreating method comprising the steps of: heating a petroleum-based diesel feed; introducing the heated petroleum-based diesel feed to a hydrotreating process; mixing a quench gas and an heated carbonaceous feed and introducing the mixture of the quench gas and the unheated carbonaceous feed to the hydrotreating process separate from the heated petroleum-based diesel feed; and co-processing the heated petroleum-based diesel feed and the unheated carbonaceous feed in the hydrotreating process wherein the hydrotreating process comprises multiple stages, and wherein the heated petroleum-based diesel feed is introduced to a first stage and the mixture of the quench gas and the unheated carbonaceous feed is fed to a later stage that is downstream of the first stage of the hydrotreating process.
