    • 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. ® KIPO & WIPO 2007
    • 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。 ®KIPO&WIPO 2007
