Abstract:

This work reports the promotion effect of Fe to Co or Ni based Mo/Al2O3 catalyst in the oxidative desulfurization (ODS) of Dibenzothiophene (DBT) as model fuel oil H2O2 and formic acid as oxidants. H2O2 exhibited higher ODS activity than formic acid over all catalyst systems. The influence of operating parameters i.e., reaction time, catalyst dose, reaction temperature and pH on oxidation process was investigated. Results reveal that maximum DBT conversion (96 %) was achieved at 60 oC and 150 min reaction time. Fe tremendously enhanced the ODS activity of Co or Ni based Mo/Al2O3 catalyts following the activity order: Fe�??Ni�??Mo/Al2O3 > Fe�??Co�??Mo/Al2O3 > Ni�??Mo/Al2O3 > Co�??Mo/Al2O3. Surface morphology and textural characterization of fresh and spent catalysts were achieved using Scanning electron microscopy (SEM), X-ray diffractometery (XRD), Energy dispersive X-Ray (EDX) analysis and BET Surface area analysis. The present approach can be effectively applied on industrial level for ODS of fuel oil crediting to its simple mechanization, low process cost, safety and application of mild operating condition.
