Abstract
The economics and thermal efficiency of an olefin-to-gasoline-conversion process utilizing catalyst beds is improved by separating the effluent product from the beds into a gas in a liquid phase, cooling the gas phase to form additional liquid and heat exchanging the liquid with the overhead gas from the separator.
