Deoxygenation of vegetable oils on NiMo-alumina catalysts

Abstract

The diploma thesis is focused on the deoxygenation of vegetable oils on MoNialumina catalysts. In the first part, Ni-, Mo- and NiMo-alumina catalysts are characterized. The catalysts are characterized by XRF (chemical composition), XRD (crystallinity), BET (specific surface area), SEM (morphology), SEM-EDX (homogeneity of the surface distribution of Ni and Mo species) and UV-Vis DRS (distribution of metal species). In the second part, the activity of NiMo-alumina catalysts in the deoxygenation of the vegetable oils is described. There are described three effects, which appeared to be important with respect to the final activity of NiMoalumina catalysts. It is the role of Ni distribution, the use of mesoporous alumina support instead of the commercial one and the comparison of NiMo-alumina catalysts prepared at the laboratory and the industrial NiMo-alumina catalysts.
