Abstract
A process is provided to produce, stabilize, dedust and upgrade synthetic oil, such as shale oil. In the process, synthetic fuels, such as oil shale, tar sands and diatomite are retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of dust. In order to minimize polymerization of the product stream and agglomerate the dust, the product stream is stabilized, upgraded, and pretreated prior to dedusting, in a hydroprocessor, such as an ebullated bed reactor, with a hydroprocessing gas in the presence of a catalyst. The hydroprocessing gas can be hydrogen, scrubbed fractionator gases, or hydrocarbon-enriched hydroprocessor off gases.
