FIELD: devices for oxychlorination. SUBSTANCE: 1,2-dichloroethane is produced from ethylene, hydrogen chloride, oxygen or oxygen-containing gas (oxychlorination) in reactor with lower limiter for catalyst fluidized bed. Located above limiter and inside catalyst fluidized bed is the first gas pipeline (distributing pipes) 4 containing nozzles 5 spaced over entire cross-section of reactor. Nozzles 5 are introduced into pipes 6 which pass effluent gas flow, mainly, in opposite direction to gas formed by catalyst fluidized bed. In this case, this gas flow is supplied through the second gas pipeline 7 located above limiter. EFFECT: reduced abrasion of reactor gas passing areas. 7 cl, 1 dwg, 1 ex
