The invention concerns a process for producing gasoline with an improved octane number, optionally accompanied by oil and/or middle distillate production, by conversion-hydroisomerization of the paraffins in the feed using a catalyst containing at least one noble metal deposited on an amorphous acidic support. Isoparaffins are separated from the gasoline cut obtained, and normal paraffins and possibly monobranched paraffins contained in the resulting effluent are isomerized using a catalyst containing at least one hydrodehydrogenating metal and at least one acidic solid. The ensemble of the streams charged with isoparaffins with an improved octane number is sent to the gasoline pool. The residue undergoes catalytic dewaxing.
