<p>The present invention relates to a method for manufacturing gasoline having an octane number over 95 from naphtha oil (1) including paraffin and naphthene. The method comprises the steps of: a) transferring the naphtha oil to a first catalytic reforming unit (2) to covert at least a part of the paraffin and/or the naphthene into an aromatic compound, and generate hydrogen; b) drawing a first distillate (3) and a hydrogen stream (4) from the first catalytic reforming unit (2); c) transferring the first distillate (3) to a separation unit (5) to separate hard hydrocarbon oil (6) containing linear paraffin and heavy hydro carbon oil (7) containing non-converted paraffin and/or naphthen; d) transferring the hard hydrocarbon oil to an isomerization unit (11) to generate isomers (12); e) transferring the heavy hydrocarbon oil to a second catalytic unit (8); and f) drawing a reformate (10) containing the aromatic compound from the second catalytic unit.</p> |
