    摘要: A filtration device for a down-flow catalytic hydroprocessing reactor is disclosed. The filtration device may be used in the petroleum and chemical processing industries in catalytic reactions of hydrocarbonaceous feedstocks in the presence of hydrogen, at an elevated temperature and pressure, to remove contaminants from mixed gas and liquid feedstreams to reactor catalyst beds. The filtration device may be provided as a horizontal tray installation at the top of a reactor, whereby feedstream liquid is passed through a filtration media in a radially inward direction from the wall of the reactor to the center of the filtration device and thereafter to the reactor catalyst bed. Among the benefits provided are the minimization of scale and small/fine particulates that reach the catalyst bed below the device, reduced pressure drop through the reactor, even when the filter is completely fouled, and the potential for added catalyst volume due to the reduced need to use catalyst grading materials.

    摘要: A method of preparing a spray dried catalyst by combining spray dried catalyst particles with wax so the spray dried catalyst particles are coated with wax, yielding wax coated catalyst particles, and shaping the wax coated catalyst to provide shaped wax coated catalyst. A method of activating Fischer-Tropsch catalyst particles containing oxides by contacting the catalyst particles with a reducing gas in an activation vessel to produce an activated catalyst, wherein contacting is performed in the absence of a liquid medium under activation conditions.

    摘要: A catalyst loading device configured to rotationally spread a catalyst in a reactor includes: a rotor disposed in the reactor and configured to be rotated; a feeder configured to feed the catalyst to the rotor; and an air delivery unit configured to generate an air flow along the catalyst fed to the rotor. The rotor is disposed to a lower end of a cylinder that is concentric with a rotary shaft of the rotor. The cylinder includes: a delivery air feed pipe configured to generate the air flow of delivery air; and a throttle mechanism configured to regulate the delivery air.
