FIELD: chemical reactors. SUBSTANCE: reactor for chemical reactions in three-phase systems (liquid, gas, solid matter) includes lower part to which reacting gas is supplied through inlet nozzle; one or several combined sections of heat exchange with one section plunged into corresponding section of synthesis; head with outlet nozzles for discharge of suspension; outlet nozzles for discharge of unreacted gases; and groups of inclined transverse partitions for separation of drawn-in particles of liquid and/or solid matter. Reactor prevents formation of possible local hot points impairing quality of catalyst and product, and provides for efficient temperature regulation by one or more heat-exchange sections, each of which is plunged into corresponding section of synthesis. EFFECT: improved design. 4 cl, 4 dwg
