Abstract
A process for reforming hydrocarbons is presented. The process involves applying process controls over the reaction temperatures to preferentially convert a portion of the hydrocarbon stream to generate an intermediate stream, which will further react with reduced endothermicity. The intermediate stream is then processed at a higher temperature, where a second reforming reactor is operated under substantially isothermal conditions.
Claims18
A process for producing aromatic compounds from a hydrocarbon feedstream, comprising:
- passing the hydrocarbon feedstream to a hydrogenation/dehydrogenation reactor system, thereby generating a first stream;
- and
- passing the first stream to a high temperature reforming reaction system thereby generating a reformate product stream.
A process for producing aromatic compounds from a hydrocarbon feedstream, comprising:
- passing the hydrocarbon feedstream to a hydrogenation/dehydrogenation reactor system, thereby generating a first stream;
- passing the first stream to a high temperature reforming reaction system thereby generating a reformate product stream, operated at an inlet temperature between 540° C. and 580° C.;
- passing a regenerated hydrogenation/dehydrogenation catalyst stream to the hydrogenation/dehydrogenation reactor system, thereby generating a hydrogenation/dehydrogenation catalyst effluent stream;
- and
- passing a regenerated reforming stream to the high temperature reforming reactor, thereby generating a reforming catalyst effluent stream.
