Publikováno v: Reaction Chemistry & Engineering. 6:672-678

Zeolites LiY, NaY, KY and ZnY were impregnated with small amounts of the corresponding metal halides (chloride, bromide and iodide) and tested as catalysts for the carboxylation of styrene oxide with CO2. The KI/KY system was tested at 100 °C and 50

Direct Carbonation of Glycerol with CO2 Catalyzed by Metal Oxides

Autor: Leonardo P. Ozorio, Claudio J. A. Mota

Publikováno v: ChemPhysChem. 18:3260-3265

Five metal oxides (ZnO, SnO2 , Fe2 O3 , CeO2 , La2 O3 ) were produced by the sol-gel method and tested in the direct carbonation of glycerol with CO2 . Initial tests with Fe2 O3 showed that the best reaction condition was 180 °C, 150 bar, and 12 h.
