Hybrid solar/autothermal gasifier: The SiC tube was fabricated with a 45û 16.7-mm diameter angled hole in the back to allow for a feedstock delivery from a gravity-driven particle feeder LAMBDA DOSER through an Al2O3 tube. The particle feeder was purged with Ar in the feedstock vessel and just below the feeder at a constant rate of 2 LN/min to prevent backflow of reacting gases. The feeder was calibrated with the purge Ar to a feeding rate of ~60 g/h.

Pyrolysis and determination of kinetic parameters with LAMBDA DOSER 1L for powder feeding: The fluidization system fed the acid hydrolysis solid residue (AHR) from miscanthus at a substantially constant rate and without blocking. In some experiments, biomass suddenly fell into the reactor due to bridging and electrostatic agglomeration of the starting material. The agglomeration was easily destroyed by tapping on the glass vessel. The motor was set at 005 (near minimum) to achieve flow rates below 1 g/min at a gas flow of 8 L/min. Improvements are being considered to achieve different combinations of feed rate and gas flow with the aim of modifying the solids residence time and equivalence ratio for gasification.
