dc.description.abstractENVIRONMENTALLY FRIENDLY HETEROGENEOUS SOL-GEL LA2O3-AL2O3 MATERIALS WITH NO ALKALINE OR ALKALINE-EARTH METALS WERE SYNTHESIZED TO BE USED AS CATALYSTS FOR BIODIESEL PRODUCTION BY A TRANSESTERIFICATION REACTION OF CANOLA OIL. THE EFFECT OF THE LA2O3 CONTENT (0, 3, 5, 7, AND 10 WT%) ON THE CATALYTIC PERFORMANCE OF THE LA2O3-AL2O3 MIXED OXIDES, AS WELL AS THE TEXTURAL, STRUCTURAL, AND SURFACE PROPERTIES, IS REPORTED. IT WAS FOUND THAT LA2O3 LOADING INCREASES THE NUMBER AND STRENGTH OF BASIC SITES UP TO 7% LA2O3-AL2O3 CATALYST WITH AN LA2O3 MONOLAYER FORMATION WITH 0.23 MMOL HIGHLY DISPERSED LA ATOMS OVER AL2O3 IS REPORTED. A CORRELATION BETWEEN CATALYTIC PERFORMANCE, INFORMED AS BIODIESEL PRODUCTION WITH BASICITY, CARBONATION DEGREE, AND LA2O3 DISPERSION IS OBTAINED. THE EXTENT OF BIODIESEL PRODUCTION (45% AT 65 A DEGREES C AND 5 H OF REACTION TIME), UNDER MILD REACTIONS CONDITIONS, FOR THE MONOLAYER LA2O3 ALUMINA CATALYST IS THE HIGHEST REPORTED UP NOW FOR NONTOXIC HETEROGENEOUS CATALYSTS.
