Abstract

Open-ended cyclone separators are disclosed which employ catalyst separation tubes to prevent separated solids discharged through an open cyclone end from being entrained in a countercurrently moving flow of process gas entering the separator through the open end. In several preferred embodiments, generally conical tubes are axially located within the cyclone open bottom. Methods for practicing the invention also are disclosed.
