Supported Catalyst Systems and Method of Making Biodiesel Products Using Such Catalysts
A heterogeneous catalyst system, a method of preparing the catalyst system and a method of forming a biodiesel product via transesterification reactions using the catalyst system is disclosed. The catalyst system according to one aspect of the present disclosure represents a class of supported mixed metal oxides that include at least calcium oxide and another metal oxide deposited on a lanthanum oxide or cerium oxide support. Preferably, the catalysts include CaO-CeO2ZLa2O3 or CaO-La2O3/CeO2. Optionally, the catalyst may further include additional metal oxides, such as CaO-La2O3-GdOxZLa2O3.
