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.
Claims19
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 fractionation unit to generate an overhead stream comprising C7 and lighter paraffins, and a bottoms stream comprising heavier hydrocarbons;
- and
- passing the overhead stream to a high temperature reforming reactor system thereby generating a reformate product stream.

- passing the first stream to a fractionation unit to generate an overhead stream comprising C7 and lighter paraffins, and a bottoms stream comprising heavier hydrocarbons and aromatics;
- passing the overhead stream to a high temperature reforming reactor system thereby generating a reformate product stream, operated at an inlet temperature between 540° C. and 580° C.;
- passing a catalyst stream to the high temperature reforming reactor system, thereby generating a first catalyst effluent stream;
- and
- passing the first catalyst effluent stream to a regenerator.
