Development of a catalyst for epoxidation of methyl esters
Pham, Tien Thanh ; Krajčovič, Jozef (referee) ; Kučerík, Jiří (advisor)
The diploma thesis is focused on the study of heterogeneous catalysts in the epoxidation of rapeseed oil methyl ester. Epoxides of these components have applications in cutting oils, where they could replace hitherto used oils from fossil sources. Epoxidation is a catalyzed reaction using homogeneous catalysts based on mineral acids. However, they have corrosive properties and they are poorly separated after the reaction. However, this work is focused on the study of heterogeneous catalysts in epoxidation. The reaction products were analyzed by GC, SIMDIS and ATR-FTIR. Advanced analytical methods such as ICP-OES, XRF, XRD, SEM, mercury porosimetry and TPR-H2 were used to determine the composition, structural, textural and reducing properties of the catalysts.
