Hydrocracking and hydrotreating shale oil in multiple catalytic reactors

Raw shale oil containing precipitable inorganic compounds such as iron and arsenic are preheated to below the precipitation temperature and then catalytically hydrocracked in an ebullated bed catalytic reactor. The metal compounds are deposited on the catalyst in the reactor, from which they are wit...

Beschreibung
Zusammenfassung:	Raw shale oil containing precipitable inorganic compounds such as iron and arsenic are preheated to below the precipitation temperature and then catalytically hydrocracked in an ebullated bed catalytic reactor. The metal compounds are deposited on the catalyst in the reactor, from which they are withdrawing along with used catalyst which is replaced with fresh catalyst. The reactor effluent is further hydrotreated in a fixed bed catalyst reactor, usually at more severe conditions of 800 DEG -840 DEG F. and 2000-2800 psig, hydrogen partial pressure. The resulting material is phase-separated and distilled to provide jet fuel and diesel oil product meeting commercial and military specifications.
