Transition Metal Sulfide Catalysts for Petroleum Upgrading – Hydrodesulfurization Reactions

Characterization of HDS/HDN active sites in cluster-derived and conventionally-prepared sulfide catalysts

The catalytic and sorptive properties of a series of sulfide cluster-derived catalysts were compared to those of an analogous series of conventionally-prepared sulfides. The cluster-derived and conventionally-prepared catalysts had similar hydrotreatment activities and chemisorbed similar amounts of 02 and NO. From infrared spectroscopy, it was observed that the clusters retained much of their ...

Dehydration of Glycerol over High Surface Area Γ-alumina Supported Heteropoly Acid Catalysts

Dehydration of glycerol was performed over heteropoly acids (HPA), viz., silicotungstic acid (H-SiW), phosphotungstic acid (H-PW), and phosphomolybdic acid (H-PMo), supported high surface area γ-alumina (HSAI-S25) catalysts. Various physico-chemical studies of these supported catalysts indicate high dispersion of the active (HPA) species on the support surface. It was observed that the catalyst...
