Evolution of Char Properties during Rapid Pyrolysis of Woody Biomass Particles under Pulverized Fuel Conditions

Rapid pyrolysis of mallee and pine wood particles (250–355 μm) was conducted in a drop-tube furnace (DTF) at 1300 °C in argon atmosphere for collecting partially pyrolyzed char samples at various particle residence times (0.31–0.68 s). A novel feature of the DTF is its double-tube configuration that realizes direct determination of the char yield via experiments. This further enables investigations into the evolutions in the char yield,...
