Brief description of the selective hydrogenation of acetylene contained in a mixture of acetylene and ethylene

摘要

Process of selective hydrogenation of acetylene contained in a mixture of acetylene and ethylene, in which said mixture is circulated through a fixed catalyst bed of palladium supports, characterizes in that one opere in the presence of a liquid phase point of high were more than that of said mixture, and the product of the hydrogenation can be separate by distillation, the said liquid phase containing at least one aromatic hydrocarbon, and comprises at least one amine in the dissolved state in the liquid phase. / p & & p & the mixture of acetylene and ethylene 1 and the liquid phase containing an aromatic hydrocarbon, and an amine 6 passing through the reactor 2. After cooling, 3, the mixture obtained is fractionated gas liquid - 4. The ethylene purified is collected, 5 and the liquid phase recycled 10.
