ABSTRACT:
A control system for regulating the reaction zone temperature in a process for the acid-catalyzed alkylation of an isoparaffin with an olefinic feed stream containing mixed olefins. The reaction zone temperature is adjusted to obtain the optimum for a given feed composition, in order to maximize the octane rating of the ultimate normally liquid alkylate product. The control system effects rapid compensation for continuing changes in feed composition which, at a fixed reaction zone temperature, otherwise adversely affect the octane rating.
