CATALIZADORES Ru/SiO2 y Ru/Al2O3 PREPARADOS POR SOL-GEL PARA HIDROGENACION DE TOLUENO
Ru(1%)/Support (SiO2 y Al2O3) were prepared by sol-gel processing, using H2O/Alcoxide molar ration and gelation pH different. The surface area increase, with the gelation acidity decrease. The TPR has shown metal-support interaction and reducibility degree different. In all catalysts the metallic di...
