Method of producing catalytic reforming raw material

The invention is a method for producing catalytic reforming raw material, cutting secondary gasoline raw material into light gasoline fraction, medium gasoline fraction and heavy gasoline fraction, where the medium gasoline fraction, optional virgin naphtha and hydrogen gas contact with first hydrofining catalyst to make alkene saturated reaction, the resultant effluent is not separated but directly contacts with second hydrofining catalyst to make hydrodesulfurization and hydro- denitrogenation reactions, and the extracted hydrogen-enriched gas is recycled and the extracted liquid enters a distillation dehydrating tower and is purified to obtain naphtha. And it can process secondary gasoline with high sulfur, nitrogen and alkene contents, and provides qualified raw material with sulfur and nitrogen contents both less than 0.5 mug/g for catalytic reforming.
