Abstract
A hydrocarbon reforming process is controlled by manipulating the addition of halogen to the reforming catalyst responsive to an isopentane signal representative of the isopentane content in the reformate.
Claims8
Reformer control process comprising
- a. automatically determining the isopentane content of a reformer product,
- b. generating an isopentane signal responsive to this determination,
- c. manipulating the addition of halogen to the reformer responsive to said isopentane signal in such a way as to increase (decrease) halogen addition responsive to a decrease (increase) in isopentane content.
In a catalytic hydrocarbon reforming process wherein a hydrocarbon feed stream is contacted under reforming conditions in a reformer with a reforming catalyst and a halogen additive, a reformed hydrocarbon effluent is withdrawn from said reformer and said reformed hydrocarbon effluent is separated into a plurality of product streams, the improvement comprising
- a. automatically determining the isopentane content of a reformed hydrocarbon effluent,
- b. generating an isopentane signal responsive to this determination,
- c. controlling the addition of halogen to the reformer responsive to said isopentane signal in such a way as to increase (decrease) halogen addition responsive to a decrease (increase) in isopentane content.
