In this work, the comercial zeolites ZSM-5 and Y were submitted to previous ionic change with NH4NO3, followed by the addition of Nb. The incorporation of Nb on its structure aims increasing the acidity and improved the catalyst activity of these zeo

The use of zeolites as support for immobilization of enzymes has been a matter of great interest recently due to the potential properties of these materials. In this work, the MCM 22 zeolite with different Si/Al ratios (15, 25 and 50) was used as sup

Experimental conditions for the production of fatty acid methyl esters (FAME) from Jatropha curcas and soybean oils using two acid heterogeneous catalysts (Amberlyst15 and KSF) was optimized, in the presence of different co-solvents (THF, acetone, pe
