Coking of Gas Oil from Slurry Hydrocracking

摘要

Integrated slurry hydrocracking (SHC) and coking methods for making slurry hydrocracking (SHC) distillates are disclosed. Representative methods involve passing a slurry comprising a vacuum column resid, a liquid coker product, and a solid particulate through an SHC reaction zone in the presence of hydrogen to obtain the SHC distillate. Atmospheric distillation in the SHC product recovery section yields a combined SHC gas oil/SHC pitch stream that is sent to coking to generate the liquid coker product. In a representative embodiment, vacuum distillation in the SHC product recovery is avoided, thereby eliminating equipment that is often most susceptible to fouling.
