Abstract:
1. A catalyst bed platform structure, comprising: a catalyst bed platform; a support pipe supporting the bottom of the catalyst bed platform, a central axis of the pipe being approximately aligned with a geometric center of the catalyst bed platform, wherein an interior volume of the support pipe comprises a catalyst dumping tube; a flow distributor separated from the catalyst bed platform by a gap, the support pipe passing through the flow distributor and attached to the flow distributor to provide support for the flow distributor; and a pipe support structure supporting the bottom of the support pipe, the pipe support structure being adapted to reside on a bottom surface of an existing reactor having walls and a top opening; wherein the catalyst bed platform is formed from components capable of passing into the existing reactor through the top opening, which has a diameter of about 28 inches or less, without welding the catalyst bed platform to a structural portion of the reactor walls; and wherein the catalyst bed platform has an opening above the interior volume of the support pipe for communication of catalyst particles from above the catalyst bed platform to the interior volume of the support pipe.
