Use of Hesperaloe funifera for the production of paper and extraction of lignin for synthesis and fuel gases

Acidification to pH 6 of the liquor resulting from the soda pulping of 500 g of plant raw material provided an amount of 13.90 g of lignin-rich solids pyrolysis of which gave a gas mixture containing 1.13% H2, 31.79% CO and 1.86% CH4 by weight. Gasification of the same sample provided a mixture containing 0.18% H2, 24.50% CO and 17.75% CH4, also by weight.
