An alkylation process and apparatus are described. The alkylation process includes pre-mixing a paraffin stream with an ionic liquid catalyst stream from a settler. The premixed paraffin and ionic liquid catalyst stream is mixed in a low-efficiency pump to form a paraffin and ionic liquid catalyst mixture. An olefin feed stream is introduced into a riser reactor. The paraffin and ionic liquid catalyst mixture is introduced into the riser reactor to form a reaction mixture comprising alkylate and the ionic liquid catalyst. The reaction mixture is separated in a settler into an ionic liquid catalyst stream and a hydrocarbon stream. |
