Adsorption mass transfer zone: Is there any basis for this fraction being 0.5 here? ?

In the book on principles of chemical engineering regarding adsorption separation, the overall material balance is described as follows: when a fixed-bed adsorption tower operates up to the breakthrough point, the unutilized height of the bed layer corresponds to a certain fraction of the height of the mass transfer zone; this fraction is generally around 0.5. Applying the material balance to the fluid phase and the adsorbed phase during the breakthrough period gives: tBqv(c1-c2) = (L – 0.5L0)AρB(x1-x2). Is there any basis for this fraction being 0.5? ?
