High Surface Area Smectite Supported Cobalt Oxides as Active Catalysts for Thiophene Hydrodesulfurization
Cobalt oxide loaded on high surface area smectites are prepared and tested in a pulse flow reactor for thiophene hydrodesulfurization (HDS). Smectites used were montmorillonite, saponite, porous saponite, hectorite and stevensite. Co-porous saponite showed the highest activity among Co-smectites, Co/Al<SUB>2</SUB>O<SUB>3</SUB>, and CoMo/Al<SUB>2</SUB>O<SUB>3</SUB> so far studied. It suggests that the property of smectite has an influence on the catalyst activity.
