Process for removing conjugated dienes from alpha-olefins

A process for improving a conjugated diene containing linear alpha-olefin product, said process comprising contacting said linear alpha-olefin product, which contains from about 100 to 1000 pm of conjugated dienes, with a montmorillonite clay, said clay consisting essentially of a montmorillonite clay which has been treated with an acid so as to replace alkali metal ions in the clay with hydrogen ions and which contains at least about 2 weight percent water, which clay is effective to reduce the conjugated diene content of said linear alpha-olefin product to less than about 100 ppm without substantial isomerization of the linear alpha-olefins to internal olefins.
