Étude et modélisation d'un procédé catalytique hétérogène d'estérification

Abstract : This study aims at analyzing and understanding the processes involved in the production of 2-ethylhexyl acrylate. This fatty ester is a derivative of acrylic acid. This reaction is accelerated by the use of a solid catalyst, a sulfonated resin acid. The specific interactions of compounds with this resin were studied at room temperature. At 90°C, the coupling of kinetics and selective affinity was analyzed and modeled in a closed reactor. A specific pilot installation was designed in laboratory. Esterification reactions were performed. in this fixed bed reactor. The tripartite structure allows the monitoring of liquid levels in all installation. A model representing this system was developed, involving selective affinity, kinetics and hydrodynamic. This model was then used to analyze trends models to determine improved operating conditions for an industrial size process
