Abstract
Official abstract text for this publication.
Methods and systems for improved catalytic reforming are disclosed. A method of catalytic reforming includes feeding a feedstream comprising C 6 -convertibles to one or more reactors; contacting the feedstream with a reforming catalyst; selecting values for a LHSV, a H2/HC ratio, and a conversion of C 6 -convertibles from a deactivation kinetic model so as to maximize a net present amount of benzene produced over a run-length of the reforming catalyst; operating the one or more reactors at the selected LHSV, the selected H2/HC ratio, and the selected conversion of C 6 -convertibles; and recovering an effluent from the reactor, wherein the effluent comprises at least about 40 wt % benzene.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for catalytic reforming comprising: providing a feedstream comprising C 6 -convertibles to one or more reactors, wherein the C 6 -convertibles are C 6 hydrocarbons having no more than one branch; 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 2 /HC ratio, and a conversion of the C 6 -convertibles; kinetically modeling a f…
