| Resumo: | 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, petroleum ether and n-hexane) in a batch reactor at fixed conditions: oil to methanol molar ratio (1:9), catalyst concentration (4.8 wt%), co-solvent mass ratio (1:1), 160°C and 6 hours. Results showed that the use of co-solvents led to a reduction in the FAME conversion. Higher conversions were obtained for Jatropha curcas compared to soybean oil. The Amberlyst15 presented an enhancement in the catalytic activity after regeneration, providing high biodiesel conversions compared to the fresh resin. The catalyst also presented stability after 5 cycles of reuse. Activity lost was observed for KSF after 2 successive batch experiments, probably due to a deactivation of acid sites |
