摘要：
It is presented the development of a kinetic model for the direct transformation of ethanol into butadiene, over a catalyst having the structure K2O: ZrO2: ZnO/MgO-SiO2, based on experimental data published by Da Ros et al. [1]. The model is developed using a reaction scheme published by the same authors, which, in addition to the formation of butadiene, includes the formation of ethene, butene and diethyl ether, as side products. The used rate expressions are of the power law type, considering the reversibility of the reactions for which the chemical equilibrium constants have low and medium values. The adequacy of the proposed kinetic model is demonstrated by the good concordance between the calculated and experimental values of ethanol conversion, butadiene yield and selectivity in reaction products. It is also confirmed by the high value of the correlation coefficient and the relatively tight statistical intervals of its parameters respectively.
