Abstract
A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and partially processing each feedstream in separate reactors. The processing includes passing the light stream to a combination hydrogenation/dehydrogenation reactor. The process reduces the energy by reducing the endothermic properties of intermediate reformed process streams.
Claims19
A process for producing aromatic compounds from a hydrocarbon feedstream, comprising:
- passing the hydrocarbon feedstream to a fractionation unit to generate an overhead stream comprising C7 and lighter hydrocarbons, and a bottoms stream comprising C8 and heavier hydrocarbons;
- passing the overhead stream to a hydrogenation/dehydrogenation reactor system thereby generating a first stream having C6 and C7 aromatics with low olefin content;
- passing the bottoms stream to a bottoms reforming unit, to generate bottoms reformate comprising aromatics;
- passing the first stream and the bottoms reformate to a substantially isothermal reactor system, thereby generating an aromatics stream;
- and
- passing the aromatics stream to a reformate splitter, to generate a reformate overhead stream comprising C7 and lighter aromatics and C7 and lighter paraffins, and a bottoms stream comprising C8 and higher hydrocarbons.
