Catalytic distillation - Wikipedia

Reflux. In most reactions carried out by catalytic distillation, the reactants are often more volatile than the products.Because of this, an internal recycling system, known as the reflux, is implemented right after the condenser (an area within the column where escaped gases are cooled down to liquids). The reflux transfers the concentrated vapor back to the catalyst area.
