FIELD: chemistry. n 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 cm 3 /g, and has the following composition, wt. %: Fe 2 O 3 – 72.68; K 2 O – 12.31; CeO 2 – 8.64; CaCO 3 +CaO – 2.24; MgO – 2.15; MoO 3 – 1.08; Na 2 O – 0.91. n EFFECT: development of a catalyst for dehydrogenation of alkylaromatic and olefin hydrocarbons, having high activity, selectivity and strength. n 3 cl, 3 tbl, 1 ex |
