摘要： An improved process is disclosed for deinking waste paper which contains nonimpact printed papers printed with xerographic and laser inks by repulping the waste paper to form a slurry in the presence of an agglomeration agent and magnetite and subjecting the slurry to a magnetic field to remove the agglomerated ink particles, whereby the improvement comprises replacement of a portion of the agglomeration agent with a copolymer of styrene and acrylic monomers which copolymer is further characterized by having a Ring and Ball softening point of 70.degree.-105.degree. C. and an number average molecular weight of 2,000 to 10,000. The magnetic treatment preferably is conducted at ambient or greater temperature, at neutral to alkaline pH, and at a low pulp consistency. Also, the process may be employed as an additional step in a conventional process for removing inks from reprographic printed papers, such as ink removal by screening, flotation, centrifugal cleaning, washing, and sedimentation with or without decantation.
摘要翻译：公开了一种改进的方法，其用于通过在附聚剂和磁铁矿的存在下重新调整废纸以形成浆料并使浆料经磁场去除聚集的废纸，其中包含用静电印刷和激光墨水印刷的非印刷印刷纸的废纸脱墨油墨颗粒，其改进包括用苯乙烯和丙烯酸单体的共聚物代替一部分附聚剂，该共聚物的进一步特征在于环球软化点为70-105℃，数均分子量 2,000到10,000。磁性处理优选在环境温度或更高的温度，中性至碱性pH和低浆浓度下进行。此外，该方法可以用作用于从复印印刷纸上去除油墨的常规方法中的附加步骤，例如通过筛选，浮选，离心清洗，洗涤和有或没有倾析的沉淀来除油。

摘要： Methods of fractionating lignocellulosic biomass using hydrotropic sulfonic acids are provided. Also provided are methods of forming lignin particles, furans, sugars, and/or lignocellulosic micro- and nanofibrils from the liquid and solid fractions produced by fractionation process. The fractionation can be carried out at low temperatures with short reaction times.

摘要： A fractionator for fractioning a suspension in at least two fractions, including a drum rotatable about a substantially horizontal access and having axially spaced end walls, a centrally arranged inlet for suspension, a flow channel for suspension in the drum, and outlets for fractions. The flow channel extends from the inlet back and forth between the end walls of the drum and radially outwards towards an outlet for the at least two fractions. Preferably the flow channel is defined by substantially concentric cylindrical walls of which every second wall is alternatively tightly connected to one or the other of the two end walls. The fractionator is useful in a continuous fractioning process.

摘要： An improved process is disclosed for removing "stickies" from waste paper which contains hot-melt and pressure-sensitive adhesives and lattices to produce high quality (high brightness, little to no dirt content) pulp with little or no fiber loss. The process involves attachment of sticky particles in the waste paper pulp to a magnetic carrier material with the help of an agglomeration agent followed by removal of the attached sticky particles by magnetic separation. The magnetic treatment preferably is conducted at ambient or greater temperature, at neutral to alkaline pH, and at a low pulp consistency. Agglomeration and magnetite addition, followed by exposure of the repulped waste paper to a magnetic field provides near complete sticky removal over exposure to the magnetic field without such pre-treatment.
