Lignocellulosic biomass, or plant biomass, is an attractive source for biofuels. The public and researchers alike are intrigued by the idea of using readily available “plant waste,” such as corn stover, sawdust, or other agricultural residue, to create carbon-neutral transportation fuels. 4, record 2, English, - lignocellulosic%20biomass

Ligno-cellulosic material is the nonstarch, fibrous part of plant materials. Cellulose, hemicellulose, and lignin are its three major constituents. Unlike carbohydrate or starch, ligno-celllulose is not easily digestible by humans... Ligno-cellulosic biomass is not part of the human food chain, and therefore its use for biogas or bio-oil does not threaten the world's food supply. 2, record 2, English, - lignocellulosic%20biomass

Cellulosic ethanol. Bioethanol can be produced from ligno-cellulosic feedstocks through the biochemical conversion of the cellulose and hemicellulose components of biomass feedstocks into fermentable sugars. The sugars are then fermented to ethanol, following the same conversion steps as conventional biofuels. Cellulosic ethanol has the potential to perform better in terms of energy balance, GHG [greenhouse gas] emissions and land-use requirements than starch-based biofuels. 3, record 3, English, - cellulosic%20ethanol

Arkenol Acid Hydrolysis Process. Strong acids are used in the pretreatment and hydrolysis of the feed stock, separating cellulose, hemicellulose, and lignin components. The acid/sugar solution is separated by a proprietary resin technology, and the acids are recirculated and reconcentrated. Any acids remaining are neutralized to form gypsum. The processes major advantages included reduced acid use, reduced gypsum production, reduced inhibitive product production, and higher ethanol yields.

La solution renfermant des acides et des sucres est séparée au moyen d'une technique brevetée à base de résine, puis les acides sont remis en circulation et reconcentrés. Les acides restants sont neutralisés pour former du gypse. Les principaux avantages du procédé sont une utilisation réduite d'acides, une production réduite de gypse, une production réduite de produits inhibiteurs et un rendement plus élevé en éthanol.

Cellulose and hemicellulose are inherently white and do not contribute to pulp color. It is generally agreed that "chromophoric groups" on the lignin are principally responsible for color; oxidative mechanisms are believed to convert part of the lignin's phenolic groups to quinone-like substances that are known to absorb light. Heavy metal ions(e. g., iron and copper) are also known to form colored complexes with the phenolic groups. Extractive materials can contribute to the color of mechanical pulps made from resinous woods. 2, record 31, English, - chromophoric%20group

Because of significant advantages, the kraft process has become established as the world's dominant pulping method. Nonetheless, the process also has some severe shortcomings, principally the low yield from wood, the comparatively high residual lignin content of bleachable grades, and the malodors caused by reduced sulfur compounds.... Most of the earlier modifications were aimed at increased retention of carbohydrates by stabilizing the end groups of the cellulose and hemicellulose polymer chains against "peeling reactions". These reactions cause dissolution of the end groups one unit at a time and consume a significant portion of the cooking chemical. 1, record 32, English, - peeling%20reaction

La place prédominante qu'occupe le procédé kraft parmi les méthodes de mise en pâte utilisées dans le monde témoigne bien du nombre d'avantages marqués qu'il offre. Le procédé comporte néanmoins de graves inconvénients dont les principaux sont un faible rendement du bois et les mauvaises odeurs causées par les composés de soufre réduits. (...) La plupart des modifications proposées visent l'obtention d'une meilleure rétention des hydrates de carbone par une stabilisation des monomères de bouts de chaîne des polymères de la cellulose et des hémicelluloses afin d'éviter leur départ.

Moderate temperature and pressure are utilized in this stage with the hemicellulose removal either acid or base assisted. The simultaneous isolation, decrystallization and partial saccharification(SIDS) of cellulose is the second stage(II) of the proposed sequence. The second stage reactions are performed at higher temperature and pressures with the intent of obtaining a fermentable oil. The third and final stage(III) is designed to convert lignin to a phenolic oil.
