ABSTRACT:
A method of operation for producing high yield of alkylate product using catalytic reactors. The catalytic reactors which cycle between reaction mode and catalyst regeneration mode have their contents exchanged with each other at the beginning of each cycle in order to increase the yield of the desired product. This exchange increases the yield by minimizing the contact of reactant in reaction mode with regenerant utilized in regeneration mode. Thus, reducing/preventing the undesirable alternate reaction between the two, which consumes the reactant making it unavailable for the production of the desired product.
