A new modification with an active substance, chromium-doped calcium oxide-based catalyst supported on alumina (Cr-Ca/?-Al2O3), was synthesized by the wetness impregnation method in the transesterification of refined waste cooking oil. 10Cr-90Ca/?-Al2O3 catalyst calcined at 700 �C was successful in a...
