Conversion of ethanol to acetaldehyde using (NiO/Al2O3) as a catalyst

Abstract

The conversion of ethanol to acetaldehyde in an atmospheric integral up flow reactor (inside diameter and height equal to 2.0 and 80 cm respectively)which was studied in order to find the optimum reaction temperature, the effect of ethanol concentration and flow rate according to the type of catalyst used. The proposed dehydrogenation method offers several advantages over the various production processes advantages are cheap raw (ethyl alcohol) and the reaction occur at atmospheric pressure. The (NiO/Al2O3) catalyst was prepared in laboratory using ten gram of catalyst in the reaction, the studied temperature range was 250-325° C at atmospheric pressure, the ethanol mole Concentration ranging between 90% - 100% mole and the flow rate was 1-4 ml/min Where (NiO/Al2O3) catalyst was employed the maximum yield of acetaldehyde is 43% mole and the conversion of ethyl alcohol at the optimum reaction conditions is 74% mole.
