Biodiesel production from the esterification of fatty acid over organophosphonic acid

다국어 초록 (Multilingual Abstract)

Biodiesel production from the esterification of fatty acid (stearic acid) with ethanol catalyzed by PA/NaY(PA = organophosphonic acid, NaY = NaY molecular sieve) was investigated, and the effects of PA loading,catalyst amount, molar ratio of ethanol to acid, reaction time and temperature on the esterificationreaction were examined. The optimumvalues for maximum esterification percentage can be obtained byusing a Box–Behnken center-united design with a minimum of experimental work. The pseudohomogeneous(PH) model has been used to simulate the experimental data, and the calculated values ofArrhenius coefficient and activation energy are 6.394 103 and 70.51 kJ/mol, respectively.
