Pilot-scale gasification of woody biomass

The gasification of pine and mixed-hardwood chips has been carried out in a pilot-scale system at a range of gas flow rates. Consuming ∼17–30 kgh −1 of feedstock, the producer gas was composed of ∼200 dm 3 m −3 carbon monoxide, 12 dm 3 m −3 carbon dioxide, 30 dm 3 m −3 methane and 190 dm 3 m −3 hydr...

Description
Summary:The gasification of pine and mixed-hardwood chips has been carried out in a pilot-scale system at a range of gas flow rates. Consuming ∼17–30 kgh −1 of feedstock, the producer gas was composed of ∼200 dm 3 m −3 carbon monoxide, 12 dm 3 m −3 carbon dioxide, 30 dm 3 m −3 methane and 190 dm 3 m −3 hydrogen, with an energy content of ∼6 MJ m −3 for both feedstocks. It was found that the efficiency of the system was enhanced at higher flow rates. ► Pilot-scale gasification was performed using woody biomass. ► Differing feedstocks were usedwith differing process conditions. ► Gas composition and energy content were monitored. ► Feedstocks resulted in similar compositional results, with slight differences observed with flowrate. ► Flowrate has a marked influence on efficiency.
