Title: | Kinetics of Transesterification of Safflower Oil to Obtain Biodiesel Using Heterogeneous Catalysis | Keywords: | potassium nitrate;potassium oxide;Kinetics, Safflower oil;Transesterification;Zeolite;info:eu-repo/classification/cti/2 | Publisher: | De Gruyter | Description: | The kinetics of the transesterification of safflower oil and methanol catalyzed by K2O/NaX was studied and modeled. The influence of the oil-methanol initial molar ratio and amount of catalyst were investigated to achieve a maximum triglycerides conversion (99%) and a final methyl esters content of 94% ± 1. A kineticmodel based on an Eley– Rideal mechanism was found to best fit the experimental data when assuming methanol adsorption as determining step. Other models derived from Langmuir – Hinshelwood – Hougen –Watson (LHHW) mechanisms were rejected based on statistical analysis, mechanistic considerations and physicochemical interpretation of the estimated parameters. | URI: | http://ri.uaemex.mx/handle20.500.11799/67621 | Other Identifiers: | http://hdl.handle.net/20.500.11799/67621 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
