主　　题：sulfur recovery Co-Mo catalyst carbon nanotubes HDS process 

摘      要：Effects of carbon nanotubes （CNT） and alumina （γ-Al2O3） supports on the catalytic activities of hydrodesulfurization （HDS） process over Co- Mo catalyst have been studied. XRD results indicated that the main active phases in CNT and γ-Al2O3 supported Co-Mo catalysts are MoO2 and MOO3, respectively. The TPR results reveal that the reduction peak temperatures of the active species on CNT supported Co-Mo catalyst is lower than those on alumina supported Co-Mo catalyst, indicating that the CNT supports favor the reduction of active species. Catalytic evaluation results displayed that the sulfur content in the reaction products on the CNT supported Co-Mo catalyst is lower than that on the alumina supported Co-Mo catalyst if the HDS reaction was carried out at a temperature above 583 K.
