System for continuously and catalytically removing arsenic from shale oil and regenerating the catalyst
A system is described for producing and upgrading shale oil, comprising: (a) an oil shale retort for liberating a gaseous effluent stream containing hydrocarbons, residual amounts of arsenic and retort water vapor; (b) means connected to the retort for receiving the effluent stream, and recovering a liquid containing shale oil, arsenic and retort water; (c) separator means connected to the liquid recovery means for receiving the liquid and separating the shale oil arsenic from the retort water; (d) retort water purification means connected to the separator means for receiving and substantially purifying the retort water; (e) a first guard bed containing an arsenic-removing absorber; (f) a second guard bed containing an arsenic-removing absorber; (g) a first means interconnecting the separator means with each of the guard beds and having a first valve means for alternately directing a flow of the shale oil and arsenic through each of the guard beds; (h) a second means interconnecting the retort water purification means with each of the guard beds and having a second value means for alternately directing a flow of the purified retort water through each of the guard beds in opposite phase relationship to the flow of shade oil and arsenic through each of the guard beds.
