| Abstract: | Effects of oxidation pretreatment and post treatment conditions onphysicochemical properties and activity recovery of typical spent residuehydrodesulfurization catalysts unloaded from refineries were studied.Experimental results indicate that both physicochemical properties and activityrecovery ratio of the spent catalysts are high after oxidization at 420 ℃. It was found that, during800 h pilot plant test, both relative sulfur removal ratio and microcarbonresidue (MCR) reduction ratio of the oxidation pretreatment catalysts can berecovered more than 85% compared with those of fresh catalysts. Compared withpost-treatment process, oxidation pretreatment has more impacts on activityrecovery of the spent catalysts. Experimental results suggest that theunrecoverable pore volume caused by metal deposition, especially pore entranceblockage by vanadium deposition, is the main reason for incomplete activityrecovery of the spent catalysts. |
