Abstract

The study represents the development of nano zinc oxide catalyst coated with alumina by co-precipitation method for dehydrogenation reaction studies. The catalyst characterization was done by transmission electron microscopy (TEM), X-Ray diffraction (XRD), BET surface analyzer and scanning electron microscopy (SEM). The reaction chosen was dehydrogenation of 2-butanol to methyl ethyl ketone (MEK) with a variation of different operating parameters such as temperature, partial pressure, reactant flow rate. The conversion was investigated by varying catalyst amount and size. The role of reaction rate on various operating parameters like temperature, the partial pressure of reactant, catalyst to feed ratio has been explored. The rate of the reaction along with order and rate constant have been calculated. The activation energy was calculated from Arrhenius law to depict the nature and efficiency of the reaction chosen.
