Abstract
The invention pertains to a process of removing phosphorous-containing impurities and preferably also dienes, from an olefin stream using a sorbent selected from the group consisting of an acidic ion exchange resin, an acidic zeolite, an acidic alumina, a neutral alumina, and an activated carbon. The olefin stream preferably comprises primarily olefins having at least 6 carbon atoms.
