ABSTRACT:
A method and apparatus for cooling dustlike or fine-grained reaction residue emanating from a reactor is disclosed. According to the method reaction residue emanating from a reactor passes downwardly into a cooling shaft where it is maintained in the form of a pile of bulk material under a gas pressure of 20 to 200 bars while cooling gas passes upwardly through said cooling shaft in counter-current and is removed at the top of said cooling shaft into the reactor. The apparatus comprises means for effecting cooling of such reactor residue.
