Diebold, J P; Scahill, J

The construction of a 1-t/d engineering 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. Virtually no char will be produced in the process because char formation is deliberately suppressed with this reactor design. The design features of the reactor are described in detail. The system is currently undergoing shakedown tests preparatory to an extensive process variable study. A report on a specialists' workshop on the fast pyrolysis of biomass held in October 1980 is included in this document.
