NOVELTY - Fluidized catalyst cracking (FCC) feedstock comprising cellulosic material and hydrocarbon co-feed (102), is contacted with FCC catalyst to produce distillate product and spent FCC catalyst. A portion of distillate product is separated from spent FCC catalyst, and spent FCC catalyst is regenerated to produce regenerated FCC catalyst. An intermediate reactor feedstock is contacted with at least one portion of regenerated FCC catalyst to produce 2-4C olefin(s) and used regenerated FCC catalyst (110). A portion of 2-4C olefin(s) is separated from used regenerated catalyst.    USE - Manufacture of distillate product and olefin(s) for preparing biofuel and/or biochemical (claimed), and biological polypropylene and/or biological polyethylene.    ADVANTAGE - The method efficiently provides distillate product and olefin(s).    DETAILED DESCRIPTION - Fluidized catalyst cracking feedstock comprising cellulosic material and hydrocarbon co-feed, is contacted with FCC catalyst at 400 degrees C or more in a riser reactor to produce a distillate product and spent FCC catalyst. A portion of distillate product is separated from spent FCC catalyst, and spent FCC catalyst is regenerated to produce regenerated FCC catalyst. An intermediate reactor feedstock is contacted with at least one portion of regenerated FCC catalyst at 500 degrees C or more in an intermediate reactor to produce 2-4C olefin(s) and used regenerated FCC catalyst. A portion of 2-4C olefin(s) is separated from the used regenerated catalyst, and a portion of used regenerated FCC catalyst is used as FCC catalyst. An INDEPENDENT CLAIM is included for preparation of biofuel and/or biochemical, which involves blending at least portion of distillate product and/or at least portion of 2-4C olefin(s) with other component(s).    DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of manufacture of distillate product and olefin(s).    Hydrocarbon co-feed (102)    Steam (104)    Primary reactor riser (106)    Used regenerated fluidized catalyst cracking catalyst (110)    Spent and stripped fluidized catalyst cracking catalyst (122)
