Chemical and biochemical conversion

Chemical and biochemical conversion Wood and other related cellulosic materials (lignocellulosics) are highly heterogeneous both physically and chemically. All their main chemical constituents (cellulose, hemicelluloses, lignin and extractives) behave differently during processing, which can traditionally be carried out in a number of ways using mechanical, chemical, biochemical and thermochemical or thermal conversion methods.1-6 Hence, besides
