摘要： The invention provides methods and compositions for enhancing the digestion of pulp in a chemical pulping process. The method uses ultra-low, economically feasible dosages of BH applied right before the pulping process begins, in a stable alkaline solution fed into white liquor line, to improve the process by saving pulping chemicals, increasing pulp brightness and yield and reducing the kappa number.

摘要： The invention provides methods and compositions for improving the rheology of red mud removed from Bayer Process liquor. The method includes adding a flocculant and a cross-linked polysaccharide to the liquor. This combination separates the red mud from the liquor but also prevents the red mud from becoming too thick. By preventing excessive thickness, the method allows for the formation of extremely dense amounts of red mud even in primary settlers because the dense red mud can still flow. As a result a user can simultaneously enjoy both easy handling of red mud and also high recovery rates of valuable alumina and caustic from the red mud.
摘要翻译：本发明提供了改进从拜耳法溶液中除去的红泥的流变性的方法和组合物。该方法包括向该液体中加入絮凝剂和交联多糖。这种组合将红泥与酒分开，但也防止红泥变得过厚。通过防止过度的厚度，该方法即使在初级沉降器中也能形成非常密集的红泥，因为致密的红泥仍然可以流动。因此，用户可以同时享受红泥的容易处理以及红泥中有价值的氧化铝和苛性碱的高回收率。

摘要： Methods of forming a silica-based products are disclosed. One method comprises: (a) providing a silica containing precursor (SCP) contained in solution that has a pH less than or equal to a pH of 7; (b) optionally doping the SCP with one or more metal species, wherein said doping occurs when the solution has a pH less than or equal to a pH of 7; (c) adjusting the pH of the solution to greater than 7; (d) adding an effective amount of salt to the solution so that the conductivity of the solution is greater than or equal to 4 mS, wherein said addition occurs prior to, simultaneous with, or after the pH adjustment in step 1c; (e) optionally filtering and drying the SCP; and (f) optionally reacting the dried product from step e with a functional group and optionally wherein the resultant functionalized dried product is at least one of the following: a functionalized metal oxide-doped or metal sulfide-doped silica product. Another method comprises: (a) providing a silica containing precursor (SCP) contained in solution that has a pH greater than 7; (b) adjusting the pH of the solution to less than or equal to 7; (c) optionally doping the SCP with one or more metal species, wherein said doping occurs when the solution has a pH less than or equal to a pH of 7; (d) adjusting the pH of the solution to greater than 7; (e) adding an effective amount of salt to the solution so that the conductivity of the solution is greater than or equal to 4 mS, wherein said addition occurs prior to, simultaneous with, or after the pH adjustment in step 2d; (f) optionally filtering and drying the SCP; and (g) optionally reacting the dried product from step f with a functional group and optionally wherein the resultant functionalized dried product is at least one of the following: a functionalized metal oxide-doped or metal sulfide-doped silica product.

摘要： The invention is directed towards methods and compositions for treating piles of low-rank coal to inhibit its spontaneous combustion. The method involves applying to the low-rank coal a composition containing VAE and crude glycerin. The composition prevents water from evaporating out of the low-rank coal. This prevents the formation within the low-rank coal of hollow openings which are a huge factor in causing its spontaneous combustion. The composition has better performance than its ingredients do alone. In fact it is so effective that certain cumbersome low-rank coal-handling methods, such as FIFO recordkeeping and inventorying, not using pinch points, or only using elbow-free equipment can be disregarded when the composition is used.
摘要翻译：本发明涉及用于处理低级煤堆以抑制其自燃的方法和组合物。该方法涉及向低等级煤应用含有VAE和粗甘油的组合物。该组合物防止水从低等级煤中蒸发掉。这防止了中空开口的低等级煤中的形成，这是导致其自发燃烧的重要因素。组合物的成分比单独使用的成分具有更好的性能。事实上，使用组合物时，某些繁琐的低等级煤处理方法（如FIFO记录保存和库存）不使用夹点或仅使用无肘设备可能会被忽略。
