    摘要: The invention provides a method of improving the digestion of wood chips into pulp. The method involves: adding a cross-linked glycerol-based polymer additive to a solution used in the digestion process. This additive is unexpectedly effective at facilitating digestion. The branched and ether structure of the additive allows it to withstand the harsh nature of a high stress environment. In addition, it is more soluble in the harsh condition than other surfactants. The structure, resistance, and particular balance between hydrophobic and hydrophilic regions, causes the additive to increases the interaction between the wood chips and the digestion chemicals. This in turn reduces the costs, the amount of additive needed, and the amount of reject wood chunks that result from the digestion process.

    摘要: Method for recovering chemicals and energy from sulphite thick liquor containing organic and inorganic compounds obtained when producing pulp by chemical delignification of fibrous raw material using a sulphite pulping process, the method including processing of the organic and inorganic compounds at a global temperature above 800° C. whereby producing partly at least one phase of a liquid material and partly at least one phase of a gaseous material. The processing is carried out by gasification of the sulphite thick liquor in a gasification reactor at sub-stoichiometric conditions and in the presence of an oxidizing medium. The reactor has an opening in its bottom in the form of a chute which opens directly into a quench compartment.

    摘要: The present invention relates to a process for the production of second generation biofuels and/or sugar based chemicals—for example ethanol, butanol etc—and/or materials—for example plastics, single cell proteins etc.—together with sulfonated lignin from lignocellulosic biomass, in particular from lignocellulosic biomass comprising, among others, annual plants, agricultural waste, or wood. In particular, the present invention relates to a process for the production of sugar based chemicals, biofuels or materials together with sulfonated lignin from lignocellulosic biomass comprising the pretreatment of a lignocellulosic biomass in a sulfite cooking step.
