Abstract
One exemplary embodiment can be a process for a hydrocarbon feed. The process can include passing a stream through a separation zone forming a void for separating one or more gases from one or more liquids and at least partially containing a catalyst. The catalyst may include at least one group VIII noble metal. Typically, the separation zone is downstream of a hydrocracking zone for reducing the operating pressure in the hydrocracking zone.
Claims17
A process for a hydrocarbon feed, comprising:
- A) providing a feed to a first hydrocracking zone;
- B) passing at least a portion of an effluent from said first hydrocracking zone to a fractionation zone;
- C) providing at least a portion of a bottom stream from said fractionation zone to a second hydrocracking zone;
- and
- D) passing a stream through a separation zone forming a void for separating one or more gases from one or more liquids and at least partially containing a catalyst comprising at least one group VIII noble metal for saturating aromatics;
- wherein the separation zone is downstream of the second hydrocracking zone.
