| 摘要 |
Acetylenes are removed from hydrocarbon mixtures containing diolefines by gas phase selective hydrogenation, wherein the mixture together with hydrogen is passed over a mixed catalyst containing copper as the main constituent and also one or more oxides, hydroxides, or salts which are convertible under the reaction conditions to oxides or hydroxides, of metals of Group I or II of the Periodic system of elements, whose oxides are not reducible below 600 DEG C., at 0-30 ats. g. and 30-250 DEG C. Suitable carriers for the catalyst include silica gel, Stuttgart mass, pumice, kaolin, or aluminium oxide. Specification 866,395 is referred to. |
