Claim Text:
1. A method for joint production of low octane gasoline and high octane gasoline, comprising the following steps: (i) in a process of atmospheric distillation or reduced pressure distillation of raw material which is crude oil, reformate oil, oil generated from catalytic cracking, oil generated from hydrogenating cracking, pyrolysis oil, or aromatic raffinate oil, each of the components with a high content from the range of C5-C12 therein is separately extracted, or each of the components having a main content therein is separately extracted in the order of content; (ii) dependent on their octane ratings of the distillates obtained in step (i) and octane indexes of target products, deriving both low octane gasoline products and high octane gasoline products, serving as fuel for compression ignition gasoline engine and spark ignition gasoline engine respectively; (iii) the distillation column is provided with at least one distillation outlet for distilling off other distillates not aimed at the target components.
