    • A catalyst for the selective hydrogenation of alkynes and dienes in C2-C5null-olefin mixtures is described. These catalysts contain (a) a metal of the tenth group of the Periodic Table, (b) a metal of the eleventh group of the Periodic Table and (c) if required, a compound of a metal of the first or second group of the Periodic Table, these metals being applied to a support which is selected from the group consisting of silica, titanium dioxide, zirconium oxides, spinels, zinc aluminates, zinc titanates or mixtures of these substances, and the metal of the eleventh group being distributed homogeneously over the cross section of the catalyst particle and the metal of the tenth group being present in the edge layer close to the surface of the catalyst particle. Such a catalyst is prepared by applying the metal of the eleventh group, preferably during the preparation of the support itself, by impregnation with a solution of a suitable metal salt.

    • The present invention provides an improved selective hydrogenation process for removing C10-C16 diolefins in the product from dehydrogenation of C10-C16 paraffins to mono-olefins, which process includes bringing the mixture stream of paraffins and olefins containing C10-C16 mono-olefins and C10-C16 diolefins into contact with a specific hydrogenation catalyst in a plurality of hydrogenation reactors connected in series under the reaction conditions for hydrogenation. Hydrogen is injected into each reactor respectively. To convert the diolefins in the mixture stream of paraffins and olefins into mono-olefins, null-alumina having a specific surface area of 50-300 m2/g and a pore volume of 0.2-2.0 cm3/g is used as the supporter of the hydrogenation catalyst, palladium is supported on the supporter as the main catalyst element and an element selected from silver, gold, tin, lead or potassium is supported on the supporter as the promoter.

    • Presented is an improvement to a previous invention involving the catalytic hydrogenation of the C2 to C5 and heavier acetylenes and dienes in a thermally cracked feed stream without significantly hydrogenating the C2 and C3 olefins. The improvement involves the use of a fixed bed hydrogenation reactor system in combination with a modified version of the catalytic distillation unit used in the prior art. The modification to the catalytic distillation unit involves improvement of the liquid recycle scheme. The fixed bed reactors combined with the modified catalytic distillation allows for 100% conversion of acetylene and helps to maintain high conversion of the other dienes and acetylenes with no ethylene or propylene conversion under a variety of conditions. These condition variations include but are not limited to the feed diene and acetylene composition, the mol % carbon monoxide in the feed, and catalyst deactivation. With catalytic distillation alone, complete conversion of the acetylene as stated above can not be achieved without ethylene loss, nor would satisfactory operation and control be possible under the variety of conditions experienced during a commercial operation.
    • 本发明涉及一种先前的发明,涉及在热裂化的进料流中C2至C5和较重的乙炔和二烯的催化氢化,而不显着氢化C2和C3烯烃。 该改进涉及使用固定床氢化反应器系统与现有技术中使用的催化蒸馏单元的改进形式。 对催化蒸馏装置的改进涉及液体循环方案的改进。 与改性催化蒸馏相结合的固定床反应器允许乙炔转化率为100%,并且有助于在各种条件下不用乙烯或丙烯转化,保持其它二烯和乙炔的高转化率。 这些条件变化包括但不限于进料二烯和乙炔组成,进料中的一氧化碳摩尔%和催化剂失活。 单独进行催化蒸馏,如果没有乙烯损失,则不能实现如上所述的乙炔的完全转化,在商业操作中经历的各种条件下也不能令人满意的操作和控制。
