摘要: The liquid-phase catalytic hydrogenation of acetylene into ethylene in the presence CO over palladium supported on graphite-like material Sibunit has been investigated. Carbon monoxide is an effective modifier selective process, exerting its effect by competing with and for chemisorption sites surface. Under optimum conditions (T = 90°C; N-methylpyrrolidone solvent; feed consisting 2 vol % C2H2, 90 H2, He balance), introduction ensures a high selectivity 89.6 ± 1.5% at conversion 95.8 1.3%, converted hydrooligomers taken account.
