Abstract

A reactor is described for exothermic sludge phase reactions which comprises as the heat exchanger an annular chamber which is covered at the top and the bottom by the reaction mass in the reactor, the annular chamber comprising a plurality of vertical passage ducts having a circular cross-section for the reaction mass, and the coolant flowing through the annular chamber between the passage ducts for the reaction mass.
