WebPFR is an idealized flow reactor such that along the direction of the flow all the reaction mixture are moving along at the same speed; there is no mixing or back flow. The … Webalong the PFR is constant at Cx. Overall a stable concentration profile is obtained at steady state, with the concentration varying in space as the reaction occurs along the flow path. 2. In an ideal PFR, is the absolute residence time for mass flowing through the reactor, not the average residence time as in a CSTR. 3.
