Progress in the entrained-flow, fast-ablative pyrolysis of biomass. Annual report, October 1980-September 1981
The construction of a l-t/d conceptual demonstration reactor to fast pyrolyze biomass chips using an ablative pyrolysis technique in a cyclonic reactor has been completed. A tar vapor-cracking tube with seven thermodynamic lengths downstream of the cyclonic reactor has the capability to change the product slate from mostly tars to nearly all gases containing significant amounts of ethylene and other olefins. Char formation is deliberately suppressed with this reactor design. The design features of the reactor are described in detail. The system has undergone extensive shakedown tests which have served to familiarize the personnel with the operation and to identify minor design modifications which have improved the system's operability and flexibility. Preliminary pyrolysis results are similar to those observed with smaller entrained-flow pyrolysis reactors.
