Abstract
Abstract A process is provided for converting feedstock comprising C2+ olefins, C2-C7 paraffins or a mixture thereof to conversion product comprising C5+ hydrocarbon compounds over a catalyst composition prepared by compositing a high-silica zeolite having a Constraint Index of from 1 to 12 with binder, followed by treating the composite under conditions effective for increasing the catalytic activity of the composition.
