Beschreibung
Zusammenfassung:	FIELD: catalyst for petrochemical processes. SUBSTANCE: invention concerns catalysts containing alumina-supported precious metals, in particular at least one alumina-supported hydrogenation-active metal, whose X-ray pattern in fresh state contains signals corresponding following interplanar spaces, 10-10m: 4.52, 2.85, 2.73, 2.44, 2.31, 2.26, 2.02, 1.91, 1.89, 1.54, 1.51, 1.49, 1.45, and 1.39, and has definite relative intensiveness. Invention also provides method of preparing catalyst involving calcination of catalyst at temperature above 900 C and below 1100 C. EFFECT: increased selectivity of catalyst. 16 cl, 18 tbl, 15 ex
