ABSTRACT:
A control system for regulating the reaction zone temperature in a process for the acid-catalyzed alkylation of an isoparaffin with a mixed olefinic feed stream. Composition characteristics of the liquid alkylate product and the olefinic feed stream are determined, and representative output signals transmitted to computer/comparator means which generates a computer output signal in response to, and as a function thereof. The computer output signal is employed to adjust the reaction zone temperature, for a given olefinic feed composition, in order to maximize the octane rating of the liquid alkylate product. The control system effects rapid compensation for feed composition changes which would otherwise adversely affect the product octane rating.
