MAZO, Paula C; RESTREPO, Gloria M; RIOS, Luis A  y  MIGUEL MARIN, Juan. Optimization of the Alkyl Esters Production from Palm Oil using Response Surface Methodology. Inf. tecnol. [online]. 2008, vol.19, n.5, pp.37-48. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000500006.

This paper studies the effect of the mass percentage of the catalyst and the molar ratio oil:alcohol for different alcohol-catalyst systems, in the optimization of alkyl esters production from crude palm oil. Factorial design 32 and response surface methodology were used and quadratic polynomial equations by a multiple regression analysis were obtained. The evaluated answer was the percentage of conversion to glycerine using the norm of the American Oil Chemists' Society, AOCS Ca 14-56.  The two variables significantly affect the conversion and the molar ratio effect is larger than the effect of the amount of catalyst. Optimum conditions vary for each system, but in general for the homogeneous catalysts the mass percentage of the catalyst is smaller (1 to 2%) than for heterogeneous (5 to 6%) and large molar ratio are required (1:12-1:40). The properties of fuel obtained are according to American standard requirements for biodiesel.

Palabras clave : biodiesel; alkyl esters; optimization; response surface; palm oil.
