(51) Int. Cl' Methods for fractional catalytic pyrolysis which allow for C013 3/36 (200601) conversion ofbiomass into a slate ofdesired products without C013 60" (200601) the need for post-pyrolysis separation are described. The C101 1/207 (200601) methods involve use of a fluid catalytic bed which is main-C1013/00 (200601) tained at a suitable pyrolysis temperature. Biomass is added (52) us C1' to the catalytic bed, preferably while entrained in a non-USPC """""""" 48/197 R; 48/2013 48/2093 48/2103 reactive gas such as nitrogen, causing the biomass to become _ _ _ 423/644 pyrolyzed and forming the desired products in vapor and gas (58) Fleld 0f Class1ficatlon Search forms, allowing the desired products to be easily separated.
