Moving bed reactor conversion process for particulate containing hydrocarbons such as shale oil and tar-sands oil

摘要

Crude oil petroleum derived from oil shale or tar sands and containing large amounts of highly abrasive particulate matter, such as rock dust or sulfated ash, is hydroprocessed in a dual function moving bed reactor which simultaneously removes particulate matter by the filter action of the catalyst bed. The effluent from the moving bed reactor is then separated and further hydroprocessed in fixed bed reactors with fresh hydrogen added to the heavier hydrocarbon fraction to promote desulfurization.
