Systems and methods for desulfurization of hydrocarbon fuels

A reaction column includes a plurality of cells, each of the plurality of cells having a lower cell portion and an upper cell portion. And the cells are sequentially arranged from the uppermost cell to the lowermost cell. The fuel inlet is configured to direct fluid through the reaction column from a lower cell portion of a lowermost cell to an upper cell portion of an uppermost cell and out of the fuel outlet. A reagent inlet is configured to direct a reagent through the reaction column from an upper cell portion of the uppermost cell to a lower cell portion of the lowermost cell. The plurality of cells can be vertically or horizontally positioned, and can also be inclined or the like. Systems and methods are also disclosed. 一种反应柱包括多个单元格，所述多个单元格中的每一者均具有下单元格部分和上单元格部分。所述单元格依次从最上端单元格到最下端单元格布置。燃料入口被配置成引导流体从最下端单元格的下单元格部分到最上端单元格的上单元格部分穿过所述反应柱，并从燃料出口流出。试剂入口被配置成引导试剂从所述最上端单元格的上单元格部分到所述最下端单元格的下单元格部分穿过所述反应柱。所述多个单元格可以竖直或水平地定位，也可以倾斜等。同样公开了系统和方法。
