Activity of Industrial Alumina-based Catalysts to Dehydration of Ethanol to Ethylene
https://doi.org/10.18412/1816-0387-2015-6-31-35
Abstract
Commercial alumina – the support of hydrotreatment catalyst IC-GO-1 (AOIC-GO-1), sorbents AN-2H and AOC-63-22, catalyst AOC-78-59 were tested for dehydration of ethanol to ethylene. The activities were measured using a flow reactor at the temperature range 375–400 °С, contact time 0,3 s. The influence of process temperature on the ethanol conversion and selectivities to the target and side products was determined. The specific activity was establishedto correlate with the weight percentage of sodium in the phase-uniform samples: Na impurities cause a decrease in the activity of commercial alumina to dehydration of ethanol to ethylene. The activities of commercial alumina-based catalytic systems were found to change in the series: AOIC-GO-1 > AN-2H > AOC-63-22 > AOC-78-59
