The Catalytic Cracking Technology Of Straight Run Gasoline Application In Industrial

Catalytic cracking as the main production plant of petroleum refining enterprises，plays animportant role in the petroleum refining process。It is the effective ways to improve the light oilyield and quality of crude oil。It is the main means of produce the LPG，gasoline，kerosene anddiesel。A two stage riser fluidized catalytic cracking technology that design by Beijing DesignInstitute of Development launch into commercial application on a0.8Mt/a fluidized catalyticcrack unit in Yanan refinery When it updates the expansion ability。After the start，the systemstable operating。In this paper，author analyse the principle and the advantages of the two stage riser fluidizecatalytic cracking technology。Through analysis of the composition and the quality of theproducts，We found that the mean yield of light liquid oil increase about2to3percent， yield ofliquid petroleum gas increase about3to4Percent。The diesel-gasoline ratio of Productincreased，the olefin content in gasoline products declined。...
