Abstract:
A three-phase slurry reactor for carrying out exothermic reactions in the presence of a catalyst in the form of catalyst particles, comprising a reactor wall enclosing a slurry zone adjacent to a freeboard zone, a reactant inlet means allowing reactant to enter the reactor before the slurry zone, and a product outlet means allowing product to exit the reactor after the freeboard zone; wherein said slurry zone is equipped with a slurry zone cooling means; wherein said freeboard zone contains means to trap catalyst particles, said means to trap catalyst particles comprising one or more corrugated plates, and a means to maintain a liquid reflux in a said freeboard zone, said means to maintain a liquid reflux comprising a cooling means to cool said means to trap catalyst particles, said liquid reflux having a characteristic of removing the trapped catalyst particles from said freeboard zone.
