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 feedstock product) rich in olefin
hydrocarbon at the top of the tower after extraction, rectification, desulfuration and dearomatization. The method carries out desulfuration and dearomatization of catalytically cracked gasoline at the same time and reclaims
solvent, thereby having the advantages of simple process, moderate operation conditions,
hydrogen source saving and low production cost.
