Zusammenfassung:The invention relates to a method for producing catalytic reformed feedstock by taking light and medium gasoline distillates as raw materials and extracting selective solvent to extract and rectify catalytically cracked gasoline in the absence of hydrogen. The method comprises the following steps: 1, fractionation prefabrication of light and medium distillate raw materials of catalytically cracked gasoline; and 2, extraction, rectification, desulfuration and dearomatization of light and medium distillates of catalytically cracked gasoline, wherein light and medium distillates of catalyticallycracked gasoline obtained in step 1 are fed into the middle-lower part of an extraction-rectification tower, while fresh extraction agent or recycled extraction agent is added from the upper part of the extraction-rectification tower; thus, the light and medium distillates contact the extraction agent inside the tower to generate desulfurized and dearomatized light-component raffinate phase (i.e.catalytic reformed feedsto
