| Sumario: | In this 265 Statistical approach %) optimization of ethanol fermentation by Saccharomyces cerevisiaeof mesoporous Al- work Pt catalysts (1 wt. to were prepared by incipient wetness impregnation employing a series in the modified MCM-41 at Al2 O3 /SiO2 mass ratios equal to 10, 25 y 40 by means of chemical grafting method. Such materials were presence of in the HDS of NaA characterized and testedValfor® zeolite dibenzothiophene (DBT) and 4,6 dimethyldibenzothiophene (4,6-DMDBT) as model molecules in a batch reactor to similar industrial conditions (320 ◦ C and 5.5 MPa). These Pt catalysts exhibited higher activity (Optimización estadística de la fermentación etanólica de Saccharomyces cerevisiae en presencia de than Pt/Al2 O3 used as a reference. The order of activities was: Pt/Al(40)MCM41 > Pt/Al(10)MCM41 ≈ Pt/Al(25)MCM41 > Pt/Al2 O3 zeolita Valfor® selectivity was mainly to desulfurization products. The most active catalyst was tested in the HDS Pt/MCM41and zeolite NaA) of 4,6-DMDBT and the results showed an important effect for Al in the HDS of highly refractory molecules. G. Inei-Shizukawa, H.
