Abstract
Conjugated diene impurities are removed from linear alpha-olefin products by contacting the linear alpha-olefin product with an acid treated montmorillonite clay which is effective to reduce the conjugated diene content of the linear alpha-olefin product, preferably to less than about 100 ppm, without substantial isomerization of the linear alpha-olefins to internal olefins.
