The transport process in the catalytic dehydrogenation of ethyl alcohol

Abstract

The vapour phase dehydrogenation of ethyl alcohol to acetaldehyde has been studied in an integral flow reactor in the temperature range of 300 to 425°C at atmospheric pressure and W/F values ranges from 0.93 to 2.915 g cat./g mole feed/h. This study has been carried out by using the integral flow reactor of diameter 18 mm over ZnO-CuO/Al₂O₃ catalyst. The maximum conversion of ethyl alcohol, selectivity of acetaldehyde yield was 48, 85.3 and 32% respectively and the concentration of by product hydrogen was 98%.
