Integrated Slurry Hydrocracking and Coking Process
First Claim
1. An integrated process for preparing a slurry hydrocracking (SHC) distillate, the process comprising:
- (a) passing a heavy hydrocarbon feedstock comprising a coker gas oil through an SHC reaction zone in the presence of hydrogen to provide an SHC effluent; and
(b) recovering said SHC distillate from said SHC effluent.

Abstract
Integrated slurry hydrocracking (SHC) and coking methods for making slurry hydrocracking (SHC) distillates are disclosed. Representative methods involve passing a slurry comprising a recycle SHC gas oil, a coker gas oil, a vacuum column resid, and a solid particulate through an SHC reaction zone in the presence of hydrogen to obtain the SHC distillate. Recovery of an SHC pitch from fractionation of the SHC reaction zone effluent provides an additional possibility for integration with the coker, and particularly via the upgrading of the SHC pitch in the coker to provide coke and lighter hydrocarbons such as SHC vacuum gas oil (VGO).

18. A method for making a distillate hydrocarbon component by integrating slurry hydrocracking (SHC), coking, and hydrotreating, the method comprising:
-
(a) passing a slurry comprising an SHC gas oil, a coker gas oil obtained from a delayed coker or a fluidized coker, and a solid particulate through an SHC reaction zone in the presence of hydrogen to provide an SHC effluent, (b) recovering said SHC gas oil, an SHC distillate, and SHC pitch from said SHC effluent, (c) recycling said SHC gas oil to said SHC reaction zone, (d) hydrotreating said SHC distillate to obtain said synthetic crude oil as a hydrotreated distillate, and (e) passing said SHC pitch to said delayed coker or said fluidized coker to obtain a coke product. - View Dependent Claims (19, 20)
