A baffle-style stripping arrangement for an FCC process having substantially horizontal stripping baffles is disclosed. The stripping baffles comprise a perforated section and a downcomer section which generates transverse movement of catalyst across the baffle to ensure adequate vertical movement of stripping media. The perforated section is covered with stripping openings to provide improved stripping efficiency and catalyst flux through the stripping vessel. The perforated section may comprise a grate. Baffles may also include an imperforate section which is vertically aligned with a downcomer section of a superjacent baffle.
