CATALYZER FOR DEHYDROGENATION OF THE ALKYL-AROMATIC HYDROCARBONS Russian patent published in 2006 - IPC B01J23/88 B01J23/83 B01J23/78 C07C15/46 

FIELD: chemical industry; catalyzers for dehydrogenation of the alkyl-aromatic hydrocarbons.

SUBSTANCE: the invention presents the catalyzer used for dehydrogenation the alkyl-aromatic hydrocarbons of the following composition (in mass%): potassium compounds (in terms of potassium oxide) - 8.0-25.0; magnesium compounds and-or calcium compounds (in terms of magnesium oxide and-or calcium oxide) - 0.2-7.0; molybdenum oxide - 0.7-7.0; cerium oxide - 1.0-15.0; Portland cement - 0.5-12.0; lanthanum oxide and-or neodymium oxide - 0.01-7.0; iron oxide - the rest. The technical result of the invention is the increase of activity, selectivity of the catalyzer, as well as the thermal stability, which increases the catalyzer service life.

EFFECT: the invention ensures the increase of activity, selectivity, thermal stability and the service life of the catalyzer.
