Abstract:
1. A method for catalytic reforming comprising: providing a feedstream comprising C contacting the feedstream with a reforming catalyst in the one or more reactors at a temperature between 700° F. and 1050° F., and at a first value for each of a LHSV, a H kinetically modeling a fouling curve of the reforming catalyst with a deactivation kinetic model comprising at least one first order aromatization reaction rate equation for a plug flow reactor, based on the first value for each of the LHSV, the H approximating a fouling curve with an analytical solution to the deactivation kinetic model; calculating run lengths of the reforming catalyst for each of a plurality of values for each of the LHSV, the H calculating net present amounts of benzene that is are produced over the run-lengths of the reforming catalyst for each of the plurality of values for each of the LHSV, the H selecting a second value for each of the LHSV, the H operating the one or more reactors at the selected second value for each of the LHSV, the H recovering an effluent from the one or more reactors, wherein the effluent comprises at least about 40 wt % benzene.
