FIELD: petrochemistry. SUBSTANCE: catalytic agent corresponds with empiric formula A1B1-2C1-3Ox. A = titanium, zirconium, silicon. B = lanthanum or yttrium; C = sodium, lithium, potassium, cesium, magnesium, calcium, strontium or barium. X = the amount of oxygen atoms determined by valency of the ingredients. The catalytic agent has C2H4 selectivity up to 33% and that of C2H6 up to 42%. EFFECT: more efficient catalytic agent with increased selectivity. 5 tbl
