FIELD: petroleum chemistry. SUBSTANCE: method of selective treatment of components of multicomponent flow is carried out in the distillation column reactor. Additional catalytic distillation units are placed as a secondary layer in the distillation column either above or lower a primary layer. Separated components are removed after reaction in the primary layer to prevent their inflow to the secondary layer. EFFECT: enhanced efficiency of process. 16 cl, 3 dwg, 3 ex
