Abstract
A chromatographic process for separating normal olefins from mixtures with branched-chain olefins with a high silica zeolitic molecular sieve, e.g., silicalites, ZSM-5, etc., having low acid catalytic reactivity, which selectively adsorbs the normal olefins, and uses alkyl-substituted cycloparaffins, e.g., methylcyclohexane, as desorbents.
