Cerium-containing catalysts for obtaining ethylene from ethanol

The catalysts Се/γ-Al 2 O 3 и Се-La/γ-Al 2 O 3 were studied by methods of electron microscopy (EM) and temperature-programmed desorption (TPD) of ammonia. Their activity was studied in reaction of ethanol dehydration with formation of ethylene. Modification of Се/γ-Al 2 O 3 catalyst by Lanthanum promotes dispersion of the catalyst and increases the amount of acidic sites. This modification positively affects the catalyst activity
