Abstract:
1. A process for producing aromatics from a naphtha feedstream comprising: passing the feedstream to a fractionation unit, thereby generating a first stream comprising light hydrocarbons, and a second stream comprising heavy hydrocarbons; passing the first stream to a first reformer, operated at a first set of reaction conditions, thereby generating a first product stream, wherein the first reformer has a catalyst inlet and a catalyst outlet, wherein the reaction conditions include a catalyst comprising a Group VIII metal on a support, and wherein the first set of reaction conditions includes a temperature greater than 540° C. and a pressure less than 310 kPa; passing the second stream to a second reformer, operated at a second set of reaction conditions, thereby generating a second product stream, wherein the second reformer has a catalyst inlet and a catalyst outlet, wherein the second set of reaction conditions includes a temperature is less than 540° C. and a pressure less than 580 kPa; passing the catalyst from a regenerator to the first reformer; passing the catalyst from the first reformer to the second reformer; and passing the first product stream and the second product stream to an aromatics separation unit.
