Title
Optimized benzaldehyde production over a new Co-ZSM-11 catalyst: Reaction parameters effects and kinetics
Abstract

•A novel and highly active Co-ZSM-11 zeolite was prepared and characterized.•The reaction parameters of the styrene partial oxidation were optimized.•A kinetic study was performed by using the initial rates method.•The Arrhenius parameters for this reaction were estimated.

An efficient Co-ZSM-11 catalyst has been synthesized for benzaldehyde production by the selective styrene oxidation. Reaction parameters such as catalyst mass, reaction temperature, molar ratio styrene/hydrogen peroxide and stirring speed were optimized, by performing the styrene oxidation reaction in a stirred batch system with fine particles of Co-ZSM-11 in suspension under microwave heating. A kinetic study was done by using the initial rate method and the Arrhenius parameters were estimated. This catalyst presents a higher reaction rate about 30% with respect of those found in literature and a higher selectivity towards benzaldehyde about 80% at optimal conditions.
