An hydroconverted effluent composition is provided, along with systems and methods for making such a composition. The hydroconverted effluent composition can have an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the hydroconverted effluent composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes
A hydroconverted effluent portion a) comprising a T10 distillation point of 29° C. or more and a T90 distillation point of 593° C. or less, or b) comprising a boiling range of 29°° C. to 593° C., the hydroconverted effluent portion comprising:
A hydroconverted vacuum gas oil fraction comprising a T5 distillation point of 343° C. or more and a T90 distillation point of 566° C. or less, the hydroconverted vacuum gas oil fraction comprising 0.6 wt % or more of nitrogen and 70 wt % to 90 wt % of combined naphthenes and aromatics relative to a weight of the hydroconverted vacuum gas oil fraction.
A hydroconverted naphtha fraction comprising a T5 distillation point of 29° C. or more and a T95 distillation point of 177° C. or less, the hydroconverted naphtha fraction comprising 0.06 wt % or more of nitrogen, 2.0 wt % to 15wt % olefins, and 15 wt % to 30 wt % of combined naphthenes and aromatics relative to a weight of the hydroconverted naphtha fraction, the hydroconverted naphtha fraction optionally further comprising a sulfur content of 0.1 wt % to 0.4 wt % relative to the weight of the hydroconverted naphtha fraction.
A hydroconverted distillate fraction comprising a T5 distillation point of 177° C. or more and a T95 distillation point of 343° C. or less, the hydroconverted distillate fraction comprising 0.2 wt % or more of nitrogen, 2.0 wt % to 10 wt % olefins, and 40 wt % to 60 wt % of combined naphthenes and aromatics relative to a weight of the hydroconverted distillate fraction.
