Abstract

A method for the removal of a spent catalyst from a fixed-bed reactor is disclosed, wherein a suction hose, in which a high pressure hose comprising a high-pressure nozzle is integrated, is introduced into the reactor, the catalyst is then size-reduced by water under high pressure passed through the nozzle, the catalyst/water mixture is removed under suction and is optionally collected in a separator.
