- ... Methyl esters produced by transesterification of vegetable oils are the main components of biodiesel, an alternative, biodegradable, non-toxic biofuel produced from renewable resources. The use of solid catalysts allows the development of environmentally friendly processes to produce biodiesel. In this work, Zn,Al-mixed oxides with different Al/(Al + Zn) molar ratios were studied as catalysts for ...
