ABSTRACT:
An improved process for the production of linear olefinic hydrocarbons by paraffin dehydrogenation and adsorptive separation is disclosed. Aromatic by-products normally formed in paraffin dehydrogenation are selectively removed using at least one aromatics removal zone. Removal of these aromatic by-products significantly increases the purity of the olefinic hydrocarbon product and increases the capacity of the adsorptive separation zone. The improved process is believed to increase the life of the adsorbent in the adsorptive separation zone and the life of the catalyst in the dehydrogenation zone.
