    • The present invention describes a Pd-catalyst, further consisting of La, Ti, Nb, K or Si, which have high ethylene selectivity even after a low temperature reduction in the se-lective hydrogenation of acetylene to ethylene and the production method of the same. A catalyst of the invention consists essentially of 0.05 to 2.0% by weight, based on the supported catalyst, of palladium and one or two metals chosen form the group consist-ing of lanthanum, niobium, titanium, potassium and silicon. The said catalyst is pre-pared by the following procedure: 1) Impregnating a support in aqueous solution of tetra amine palladium hydroxide, followed by drying and calcination; 2) The second and, if necessary, a third metal is impregnated by impregnating the Pd-catalyst in the solution of the metal precursor followed by drying and calcina- tion; 3) The catalyst according to step is then reduced in hydrogen at 200°C to 600°C for 1 to 5 hours.
    • 本发明描述了一种Pd催化剂,其进一步由La,Ti,Nb,K或Si组成,即使在乙炔对乙烯的选择性氢化中的低温还原后也具有高的乙烯选择性及其制备方法 。 本发明的催化剂基本上由基于负载型催化剂的0.05至2.0重量%的钯和选自镧,铌,钛,钾和硅组成的组中的一种或两种金属组成。 所述催化剂通过以下步骤预处理:1)将载体浸渍在四胺氢氧化钯水溶液中,然后干燥和煅烧; 2)通过将Pd催化剂浸渍在金属前体溶液中,然后干燥和煅烧来浸渍第二种金属和必要时的第三种金属; 3)然后根据步骤的催化剂在200℃至600℃的氢气中还原1至5小时。

    • The invention relates to a method for producing a flow of aliphatic hydrocarbons which comprise from 5 to 12 carbon atoms per molecule and whose content in linear alpha-olefins is increased with respect to a feeding flow of aliphatic hydrocarbons comprising from 5 to 12 carbon atoms per molecule and containing linear alpha-olefins, internal linear olefins and dienes. The inventive method consists in bringing the feeding flow to a first distillation area D1 comprising at least 5 theoretical separation stages, wherein linear alpha-olefins are partially or totally separated in the form of a steam flux component which also contains dienes and on whose lower end a fluid flow partially or totally depleted of the linear alpha-olefins is obtainable, in introducing said fluid flow from the lower end of the first distillation area D1 into an isomerisation unit which is provided with an isomerisation catalyst in which the internal linear olefins are partially or totally isomerised into linear alpha-olefins and the thus formed linear alpha-olefins are separated in the form of the steam flux component mounting to the first distillation area D1 and entering a selective hydrogenation unit in which at least one part of dienes are selectively hydrogenated into olefins in a low-isomerisation selective hydrogenation catalyst and the thus obtainable steam flux is extracted, totally or partially condensed and removed in the form of a product flow whose content in linear alpha-olefins is increased with respect to the feeding stream.
