The present disclosure generally relates to methods and systems for reforming and isomerizing hydrocarbons. More particularly, the present disclosure relates to a novel combination of two traditionally separate reforming and isomerization reaction zones. A first hydrocarbon stream comprising C5-C6 hydrocarbons is isomerized in a first isomerization zone. A second hydrocarbon stream comprising C7+ hydrocarbons is reformed thus producing a C7 hydrocarbon stream and a C8 hydrocarbon stream. The reformed C7 stream is then isomerized in a second isomerization zone.
