Abstract
Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.
