SHS of Co and Co–V Catalysts for Deep Oxidation/Hydrogenation Processes

Abstract—Polymetallic Co90–V10 catalyst was derived from an SHS-produced Co–V–Al precursor and its performance in the deep oxidation of СО, propane and in the СО₂ hydrogenation was determined and compared with that of previously synthesized Co100 and Co95–V5 polymetallic catalysts. The precursor and catalyst were characterized by XRD, SEM, and BET analyses. In the processes of deep oxidation, Co90–V10 catalyst showed the best results. The CO₂ hydrogenation turned independent of V content of catalyst. A maximum of CO₂ conversion (65% at 350°C) was exhibited by Со100 catalyst. The СО₂ conversion over Co100 and Co95–V5 catalysts was found to show a maximum at a gas hour space velocity (GHSV) of 6000 h^–1.
