Abstract
An oligomerization process for the production of higher aliphatic olefins is disclosed. In the process, a liquid oligomerization feed stream comprising lighter aliphatic olefins is passed to a reactor vessel. The liquid oligomerization feed stream is transported upwardly in the reactor vessel against gravity through a fixed bed of solid oligomerization catalyst under oligomerization conditions. The catalyst has a Hammett acidity value of −4 or less. A liquid oligomerization effluent stream is recovered comprising product higher aliphatic olefins.
