Impact of Biodiesel Source Material and Chemical

  • Can methanol convert FFA into fatty acid methyl ester?
  • The esterification of free fatty acids (FFA) found in crude palm oil (CPO) off grade with methanol is a promising technique to convert FFA into valuable fatty acid methyl ester (FAME, biodiesel) and obtain a FFA-free oil that can be further transesterified using alkali bases.
  • How to determine free fatty acids in palm oil?
  • The traditional method for determination of free fatty acids in palm oil is through titration of the sample against potassium hydroxide in hot 2-propanol solutions by using phenolphthalein as indicator.
  • Can palm oil be a low-cost feedstock for biodiesel production?
  • Crude off-grade palm oil or low-grade crude palm oil (LGCPO) has potential as a low-cost feedstock for biodiesel production, with 5-20% of free fatty acids (Supardan and Satriana, 2009 ).
  • What is acid-catalyzed esterification?
  • Acid-catalyzed esterification is an equilibrium reaction, much more methanol than that given by the stoichiometric 1:1 mole ratio of methanol to oil is required to drive the reaction to completion, i.e., to form 1 mole of FAME from 1 mole of oil.
  • Can unprocessed palm fruit be converted to low grade CPO?
  • Therefore, the excess of unprocessing palm fruit can be converted to low grade CPO by simple processing as feedstock for biodiesel production by the farmers to increase its economic value. Low grade CPO is one of potential low-cost feedstock for biodiesel production which contained 5-20% of free fatty acids (FFA).
  • Does acid catalyzed esterification improve biodiesel yield?
  • It was reported that the two-step process of acid catalyzed esterification followed by alkaline catalyzed transesterification reaction improved the biodiesel yield (Crabbe et al., 2001; Ghadge and Raheman, 2005; Veljkovic et al., 2006; Tiwari et al., 2007).
