Series flow second-stage hydrocracking of high nitrogen H-Coal liquid to gasoline has been completed. Complete conversion to gasoline was attained at moderate process conditions. Because of the presence of significant amounts of heptane insolubles, the raw EDS process gas oil was not suitable as hydrocracker charge stock. Hydrotreating converted these insolubles completely to distillate and lowered the nitrogen content well below the level required for a second-stage hydrocracking feedstock. Hydrotreating process variable studies on raw EDS liquid product have been started. The first series of experiments was conducted at 250 psig above base pressure, 25/sup 0/C above base temperature, and three space velocities. The preparative H-Coal gas oil hydrotreating run for preparing a FCC feedstock with 11 percent hydrogen was completed. Another preparative run, aimed at preparing a 13 percent hydrogen feedstock, is now near completion.
