Processes for increasing an octane value of a gasoline component

A process for production of a gasoline blend, the process comprising:

• separating a naphtha feed into a C5 stream comprising iC5, a stream comprising C6 and nC5 hydrocarbons, a C7 stream comprising C7 hydrocarbons, and a heavy stream comprising C8 and heavier hydrocarbons;
• isomerizing, in a C6 isomerization zone at isomerization conditions, the stream comprising C6 and nC5 hydrocarbons to form a C6 isomerization effluent;
• isomerizing, in a C7 isomerization zone at isomerization conditions, the C7 stream comprising C7 hydrocarbons to form a C7 isomerization effluent;
• dehydrogenating, in a C7 dehydrogenation zone, at least a portion of the C7 isomerization effluent to form a C7 isomerized dehydrogenation effluent comprising C7 olefins;
• reforming, in a reforming zone under reforming conditions, the heavy stream to form a reformate stream;
• and
• forming the gasoline blend by blending the C5 stream comprising iC5, a portion of the C6 isomerization effluent, the C7 isomerized dehydrogenation effluent, and the reformate stream.

• isomerizing the C5 stream in a C5 isomerization zone to produce an effluent with an increased level of iC5 hydrocarbons;
• passing the C5 isomerized effluent to a C5 dehydrogenation zone configured to provide a C5 isomerized dehydrogenated effluent;
• isomerizing, in a C6 isomerization zone at isomerization conditions, at least a portion of the stream comprising C6 hydrocarbons to form a C6 isomerization effluent;
• isomerizing, in a C7 isomerization zone at isomerization conditions, the C7 stream comprising C7 hydrocarbons to form a C7 isomerization effluent;
