"OLEFIN HYDROGENATION METHOD FOR ADSORPTIVE PROCESS FEEDSTREAMS" ABSTRACT A process is disclosed for hydrotreating olefin- containing hydrocarbon streams for the purpose of producing very low olefin concentrations without the use of high pressure hydrotreating. The process is useful in preparing feeds to adsorptive separation zones. In the process the effluent of a hydrotreating reaction zone is passed into a stripping column. Preferably, substantially all liquid flowing downward through the lower section of the column is withdrawn and then passed through a hydrogenation reactor. The hydrogenation reactor effluent is passed into the bottom of the column to allow removal of dissolved hydrogen.
