Abstract—The zeolites and oxide catalysts are investigated in the conversion of bio-ethanol. It is shown that the formation of the products depends on the feedstock composition and the composition of the reaction mixture. It is determined that at the conversion of bio-ethanol over the zeolites 3A, 4A, 5A, and 13 X products of cracking, reforming, dehydration and oligomerization of ethylene are formed. The cerium-containing catalysts are studied via electron microscopy and temperature - programmed desorption of ammonia. Doping Ce/γ-Al2O3 catalyst with lanthanum is shown to increase its dispersion and the number of active acid sites, thereby improving its activity.

Index Terms—Bio-ethanol, zeolite, cerium-containing catalyst, aromatic hydrocarbons, ethylene, conversion.
