    • A radial flow reactor and process for reacting fluid is disclosed. The reactor includes a series of peripheral inlet distributor members which direct fluid flow radially inwardly to an annular catalyst bed. Each inlet distributor member includes an elongate body defining an interior, the body including a screen wall facing the catalyst bed; an opposing outer wall spaced radially outwardly from screen wall, an inlet to introduce fluid into the interior; and a perforated baffle wall positioned between the outer wall and screen wall. The perforated baffle wall divides the interior into a first chamber for guiding flow from the inlet in an axial direction along the elongate body and a second chamber for guiding flow radially inwardly from the baffle wall toward the screen wall. The baffle wall is effective to reduce a pressure gradient along the screen, thereby improving flow uniformity and optimizing use of catalyst material.
    • 公开了径向流动反应器和用于使流体反应的方法。 反应器包括一系列周边入口分配器构件,其将流体径向向内引导到环形催化剂床。 每个入口分配器构件包括限定内部的细长主体,主体包括面向催化剂床的筛壁; 与屏幕壁径向向外隔开的相对的外壁,将流体引入内部的入口; 以及定位在外壁和筛壁之间的穿孔挡板壁。 穿孔挡板壁将内部分成第一室,用于引导沿着细长主体沿着轴向方向从入口流出的第二室和用于引导从挡板壁向屏幕壁径向向内流动的第二室。 挡板可以有效地降低屏幕的压力梯度,从而提高流动均匀性并优化催化剂材料的使用。
