Abstract

1469175 Alkylating isoparaffins UOP Inc 6 Aug 1974 34576/74 Heading C5E A process for alkylating an isoparaffin with a 6 3 -C s mono-olefin comprises the steps of: (a) admixing a first portion of said mono-olefin with said isoparaffin and contacting the resulting first hydrocarbon mixture with a first hydrogen fluoride alkylation catalyst phase in a first alkylation reaction zone at hydrogen fluoride alkylation conditions to form a first alkylation reaction mixture; (b) removing said first alkylation reaction mixture from said first alkylation reaction zone, settling said first alkylation reaction mixture to provide a first settled hydrocarbons phase and said first hydrogen fluoride catalyst phase, and recycling said first catalyst phase to said first alkylation reaction zone; (c) admixing a second portion of said mono-olefin with at least a portion of said settled hydrocarbons phase and contacting the resulting second hydrocarbon mixture with a second hydrogen fluoride catalyst phase in a second alkylation reaction zone at hydrogen fluoride alkylation conditions to form a second alkylation reaction mixture; (d) removing said second alkylation reaction mixture from said second alkylation reaction zone, settling said second alkylation reaction mixture to provide a second settled hydrocarbons phase and said second hydrogen fluoride catalyst phase, and recycling said second catalyst phase to said second alkylation reaction zone; and, (e) fractionating said second settled hydrocarbons phase to provide at least a higher boiling product stream and a lower boiling isoparaffin stream, recycling the isoparaffin stream to step (a) and recovering the alkylation reaction product from the product stream.
