This patent describes a system for performing an alkylation process of the type which includes settler vessel means for receiving an admixture of liquid hydrocarbons and liquid catalyst and allowing the separation of the liquid hydrocarbons from the liquid catalysts; catalyst cooler means for cooling liquid catalyst; first conduit means in fluid flow communication between a lower portion of the settler vessel means and the catalyst cooler means; riser-reactor means in fluid flow communication among the catalyst cooler means, the settler vessel means, and a source of liquid hydrocarbon feed for conducting cooled catalyst from the catalyst cooler means and liquid hydrocarbon from the source of liquid hydrocarbon feed in admixture to the settler vessel means; and the settler vessel means, the first conduit means, the catalyst cooler means, and the riser-reactor means each being positioned at an elevation above a first elevation. The improvement comprises: catalyst storage vessel means; second conduit means; first valve means.
