FIELD: chemistry.
SUBSTANCE: invention relates to production of catalysts, specifically to a catalyst for dehydrogenation of olefinic and alkylaromatic hydrocarbons. Catalyst contains compounds of iron, potassium and promoters: sodium oxide, magnesium oxide, calcium oxide and calcium carbonate, molybdenum (VI) oxide, cerium (IV) oxide. As iron compounds, catalyst contains potassium ferrites. Catalyst has a pore size distribution as follows: pore volume radius of at least 5 nm is 9 %, 5–20 nm – 21 % and 20–50 nm – 70 %, and a total pore volume of 0.0057 cm3/g, and has the following composition, wt. %: Fe2O3 – 72.68; K2O – 12.31; CeO2 – 8.64; CaCO3+CaO – 2.24; MgO – 2.15; MoO3 – 1.08; Na2O – 0.91.
EFFECT: development of a catalyst for dehydrogenation of alkylaromatic and olefin hydrocarbons, having high activity, selectivity and strength.
