摘要： A method for producing thermomechanical or chemi-thermomechanical pulp is provided. The process is characterized as having a reduced specific energy demand during refining. The process involves processing a pretreated wood material using one or more high consistency refining steps to produce a first pulp, optionally applying a chelating agent to the first pulp during HC refining to produce a stabilized pulp and treating the first or stabilized pulp with an alkaline-peroxide liquor to produce a treated pulp. The treated pulp is then processed by one or more second low consistency refining steps. Alternatively, the first pulp or stabilized pulp may be divided into a primary and secondary stream. The primary stream is treated with alkaline-peroxide liquor to produce a treated pulp. The secondary stream is processed using a secondary HC refining step to produce a partially refined pulp, and removing latency of the partially refined pulp and the treated pulp is removed in a common location. The treated pulp and the partially treated pulp is processed by one or more than one second low consistency refining step to produce a final pulp. The methods utilize less energy when compared with a method for producing pulp that requires both primary and secondary high consistency refining stages.

摘要： The invention provides a method and apparatus for optimally feeding an ASA emulsion into a papermaking process. An intense transmission of ultrasonic energy rapidly and efficiently forms an ASA emulsion. Nearly simultaneous to forming the emulsion, the emulsion is fed into a high-speed dual conduit feeding apparatus, which quickly mixes the ASA emulsion with other chemicals and feeds the mixture directly into a papermaking process. The invention operates so fast that virtually no hydrolysis of the ASA occurs. This both prevents damage to the papermaking machinery and improves the quality of the produced paper. The invention operates 10-20 times faster than mechanical based emulsion methods and requires 1/7 as much energy to operate. The invention also self-monitors the process and can automatically correct any detected problems with the fed ASA emulsion.

Embodiments of the method comprise conveying the cellulosic feedstock through an enclosed volume, adding moisture to the cellulosic feedstock simultaneously at multiple spaced-apart moisture injection points as the cellulosic feedstock travels through the volume, and heating the cellulosic feedstock as it travels through the volume to obtain a heated moistened feedstock. Embodiments of the apparatus comprise a shell defining a treatment chamber having a lower inner surface. The treatment chamber has an inlet and an outlet spaced longitudinally apart from the inlet to define an axial length. A conveyance member is housed within the shell and is configured to sweep the lower inner surface. A plurality of injection ports are provided in at least one of the shell and the conveyance member.

摘要： A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about I and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW fibers and a mixture of HW fibers and modified HW fibers are disclosed.
