    Abstract: A fluid injection lozenge comprises two tubes supporting a perforate member forming a cage enclosing the space between the tubes. Each tube has a series of perforations along its length so that a fluid can be injected, through the tube, into the enclosed space. The lozenges are of use in catalytic converters of either the axial or radial flow design. In the case of a radial flow converter, a plurality of tubes are provided, preferably connected in pairs by the perforate members, to form a squirrel cage structure, disposed in the catalyst bed.

    Abstract translation: 流体注射锭剂包括两个支撑穿孔构件的管，该穿孔构件形成围绕管之间的空间的笼。 每个管沿其长度具有一系列穿孔，使得流体可以通过管注入封闭空间。 锭剂可用于轴向或径向流动设计的催化转化器。 在径向流转换器的情况下，提供多个管，优选地由穿孔构件成对连接，以形成设置在催化剂床中的鼠笼结构。

    Abstract: A device for the recovery of noble metals emanating from the surface of catalysts used in high pressure gas reactions involving absorbing the noble metal dispersed in the reaction gas in an intercepting bed formed of acid-soluble metal oxides in which the external boundary surface of the intercepting bed is 1.5 to 20 times the cross-sectional area of the catalyst surface. The thickness of the intercepting bed, in the direction of gas flow through the material thereof, is 20 to 40 mm., and the flow of the reaction gases in the intercepting bed is in a direction parallel to the plane of the supporting base of the bed.
