Reducing the hemicelluloses in SRC willow to <12% by torrefaction results in higher quality syngas from BFB gasification.
Heavily torrefied SRC willow produced 47% less tar than lightly torrefied or non-torrefied SRC willow in a BFB gasifier.
The H2/CO ratio of syngas was greater for heavily torrefied SRC willow compared to lightly torrefied SRC willow.
