Abstract: Impregnated carbon adsorbents for the removal of mercury from liquid hydrocarbons are used in a variety of applications. The activated carbon impregnated adsorbents in the present invention remain effective in removing mercury. Generally, these activated carbons are comprised of an activated carbon adsorbent impregnated with a composition containing metal halide or other reducing halide, supplemented according to the desired characteristics with other elements. The formulation of the impregnants in the present invention can be varied to adjust the performance characteristics so as to meet the desired mercury removal performance criteria, to achieve enhanced removal of organic bound mercury from liquid hydrocarbon, and to have other advantages useful in a variety of applications. These impregnated carbon adsorbents possess desirable qualities regarding their ability to remove even trace levels of mercury from liquid hydrocarbon without a leaching effect of the impregnants used.

Abstract translation: 用于从液体烃中除去汞的浸渍碳吸附剂用于各种应用中。 本发明中活性炭浸渍的吸附剂在去除汞方面仍然有效。 通常，这些活性炭由浸渍有含有金属卤化物或其它还原卤化物的组合物的活性炭吸附剂组成，根据期望的特性与其它元素补充。 可以改变本发明中的浸渍剂的配方以调节性能特征以满足期望的除汞性能标准，以实现从液态碳氢化合物中有机结合的汞的增强去除，并且具有其它优点，可用于各种 应用程序。 这些浸渍的碳吸附剂对于从液态烃中除去甚至痕量汞的能力而具有所需的质量，而没有所用浸渍剂的浸出效应。
