发明名称 Lipohydrophilic glycerol based polymers as digestion aids for improving wood pulping processes
摘要 The invention provides a method of improving the digestion of wood chips into pulp. The method involves: adding a liphohydrophilic 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 highly alkaline environment. In addition, it is more soluble in high pH 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.
