Abstract
A process for the oligomerization of olefins includes treating, e.g., water washing, an olefin-containing hydrocarbon stream to lower the concentration of an organic nitrogen-containing Lewis base contained therein until the treated hydrocarbon stream is substantially free of the Lewis base; and subsequently contacting the treated hydrocarbon stream with a molecular sieve catalyst to produce a product including at least one oligomer.
