Upgrading of coal liquids. Interim report. Hydrotreating and reforming H-Coal process derived naphthas
The objective of this work was to evaluate the applicability of commercial UOP hydrotreating and reforming processes to naphthas derived from the H-Coal process. Three naphthas were studied. One was the primary naphtha generated from the H-Coal syncrude operation. The other two products were from hydrocracking H-Coal gas oil. The primary H-Coal naphtha was rerun in a laboratory column to remove color materials and heavy ends generated during storage. Because of the high contents of nitrogen, sulfur and oxygen, this naphtha was catalytically hydrotreated at moderate conditions to bring the heterocyclics content within the limits acceptable as a Platformer charge stock. The upgraded H-Coal naphtha and the two hydrocracked naphthas were reformed over a commercial Platforming (registered trademark) catalyst in bench scale continuous units. Data were obtained at base pressure, 1.5 x base space velocity, and a range of temperatures for the purpose of constructing yield octane curves. Since all these feeds were highly naphthenic, reforming was successfully carried out at high space velocity and relatively low temperatures with high gasoline yields. In addition to routine analyses, mass spectroscopy (MS) analyses were carried out on the primary H-Coal naphtha, Platformer feeds, and selected reformates.
