Abstract

Fluidized bed pyrolyzers are commonly used for biomass fast pyrolysis to maximize the pyrolysis oil yield. Homogenous secondary pyrolysis reactions in a fluidized bed scenario were studied. The fluidized gas temperature was a more critical factor than vapor residence time in causing secondary reactions, while feedstock size showed a little impact. The downward flow of the pyrolysis volatiles observed along the reactor wall is to be considered in the design of the feeding and fluidized bed. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).
