Description

The present study aimed synthesizes by combustion reaction and characterization of the spinel CoFe2O4 and NiFe2O4, and evaluation in the esterification and transesterification reaction of cottonseed oil for biodiesel. The samples were characterized by XRD, nitrogen adsorption/desorption (BET), SEM and transesterification e esterification reaction of the cottonseed oil for biodiesel. The results show that the synthesis was effective in achievement the CoFe2O4 and NiFe2O4 with surface area 23.75 and 18.18 m2g1. The results for esterification indicated that CoFe2O4 conversion 16.8 and 38.6%, however for transesterification reaction was observed that NiFe2O4 conversion 8.6 and 16.8% for ethanol and methanol, respectively.
