    • A catalyst loading hopper suitable for positioning in vertical position above a reactor vessel, having an inlet at its upper end, a catalyst outlet at its lower end and a diagonally-disposed baffle extending downwardly across the hopper but terminating short of one of the walls of the hopper and a weir adjustably arranged so as to control the flow of catalysts through the hopper. There is a dust outlet at the top of the hopper, which may be connected to a conduit so as to draw dust away from the upper end of the hopper and a screen at the bottom of the hopper to separate the catalyst from any fines or undersized catalyst particles. The screen feeds into a catalyst outlet which, in turn, feeds into a conduit, which extends into the reactor vessel so as to allow arrangement of the cleaned catalyst pellets in layers in the vessel. A gas nozzle opens in the wall of the hopper and allows dust to be blown from the catalyst pellets and through the dust outlet to be collected in a suitable filter. The fines and undersized catalyst portions can be drawn through a fines outlet and conduit to a suitable receptacle.
    • 一种催化剂装载料斗,其适于定位在反应器容器上方的垂直位置,在其上端具有入口,其下端具有催化剂出口,并且斜向设置的挡板向下延伸穿过料斗,但是终止于 料斗和堰可调,以便控制催化剂通过料斗的流动。 在料斗的顶部有一个灰尘出口,它可以连接到导管上,以便从料斗的上端吸入灰尘,并在料斗的底部设置一个筛网,以将催化剂与任何细粉或尺寸过小的 催化剂颗粒。 筛网进入催化剂出口,催化剂出口进而进入导管,该管道延伸到反应器容器中,以允许清洁的催化剂颗粒在容器中层叠。 气体喷嘴在料斗的壁上开口,允许灰尘从催化剂颗粒中吹出并通过灰尘出口被收集在合适的过滤器中。 细粉和尺寸过小的催化剂部分可以通过细粉出口和管道被吸入合适的容器。
