Abstract
Highly selective production of ethylene via continuous oxidative dehydrogenation of ethane has been established in the oxygen conductive (Dy2O3/MgO)-(Li-K)Cl composite membrane reactor. The disk-shape membrane was fabricated by pellet-pressing and characterised in terms of nitrogen physisorption, XRD and SEM. Specific surface area and pore volume decreases with increasing chlorides content with invariable values ≥10.6% chlorides content. SEM analysis reveals exposure of chlorides particles on the membrane surface. The presence of alkali chlorides promoted conversion of ethane selective to ethylene. The membrane reaction exhibited higher selectivity of ethylene than the fixed bed reaction. Reaction over 10.6% chlorides loaded membrane delivered highest ethylene selectivity (98%) and largest specific ethylene formation rate. Extended contact time and higher temperature served to further enhance ethylene yield.
