Article by Amanda Doyle Honeywell OUP Chevron’s Salt Lake City refinery is world’s first commercial-scale process unit using ISOALKY technology to produce ionic liquid-based alkylate for higher octane motor fuels CHEVRON and Honeywell have started commercial operation of a new alkylation process using an ionic liquid catalyst that is safer and more efficient than traditional methods. Alkylation combines light olefins such as butylene with isobutane to create a high-octane blending component that can be used to produce high-octane gasoline. The new alkylation process was developed by Chevron and licensed to Honeywell, and is branded ISOALKY. According to Honeywell, it is the first new successful liquid alkylation technology to be introduced in more than 75 years. The
