Abstract
The present disclosure relates to the aromatization of hydrocarbons with an aromatization catalyst, including methods of aromatization comprising the use of a continuous catalyst regeneration type reformer.
Claims20
A reforming reactor system comprising:
- a continuous catalyst regeneration (CCR) system comprising at least one reactor stack, wherein each reactor stack comprises at least two radial flow reactors that separately comprise a reforming catalyst capable of catalyzing the conversion of hydrocarbons in a hydrocarbon feed to provide a reactor effluent comprising aromatic hydrocarbons;
- a regeneration reactor system connected to the at least one reactor stack via a spent catalyst transfer system, and configured for regenerating the reforming catalyst;
- wherein the reforming reactor system is configured for movement of the reforming catalyst through the at least one reactor stack over a time period of at least 180 days;
- and
- wherein the reforming catalyst comprises a Group VIII metal, a silica-bound L-zeolite support, and at least one halogen.
2 more elements
A method of operating a reforming reactor system, the method comprising:
- operating the reactors of a stacked reactor system comprising at least one reactor stack, wherein each of the at least one reactor stacks comprises at least two stacked radial flow reactors;
- each radial flow reactor containing a reforming catalyst capable of catalyzing the conversion of hydrocarbons in a hydrocarbon feed selected from convertible hydrocarbons having six or seven carbon atoms without an internal quaternary carbon, and convertible hydrocarbons having six carbon atoms without two adjacent internal tertiary carbons, to provide a reactor effluent comprising aromatic hydrocarbons, and wherein the reforming catalyst comprises a Group VIII metal, a silica-bound L-zeolite support, and at least one halogen;
- wherein the stacked reactor system is operable to provide movement of the reforming catalyst through the at least one reactor stack over a time period of at least 180 days and to a regeneration system via a catalyst transfer system.
