ABSTRACT:
This invention generally relates to a new method and apparatus for the fast pyrolysis of carbonaceous materials involving rapid mixing, high heat transfer rates, precisely controlled short uniform residence times and rapid primary product quench in an upflow, entrained-bed, transport reactor with heat carrier solids recirculation. A carbonaceous feedstock, a non-oxidative transport gas and inorganic particulate heat supplying material are rapidly mixed in a reactor base section, then transported upward through an entrained-bed tubular reactor. A cyclonic hot solids recirculation system separates the solids from the non-condensible gases and primary product vapors and returns them to the mixer. Product vapors are rapidly quenched to provide maximum yields of liquids, petrochemicals, high value gases and selected valuable chemicals.
