This paper described the technological principle of Fenton fluidized-bed oxidation techniques. The advantages of Fenton fluidized-bed techniques including higher pollutant removal rate, lower chemicals consumption and sludge production comparing with the traditional Fenton oxidation process were discussed. The CODCr removal rate could reach more than 90% and the color removal rate more than 99% of the pulping and papermaking effluent firstly treated with biological process then followed by Fenton fluidized-bed oxidation advanced treatment.

In this study, we employed nanocrystalline cellulose (NCC) as an efficient dispersant to perpare alkyl ketene dimer (AKD) emulsion. The particle size and zeta potential of AKD/NCC emulsion were measured, which were approximately 5 μm and -50 mV, respectively. The surface-sized paper possessed multiple barriers properties. The air permeability of surface-sized paper was 0.29 μm/Pa s and the sizing degree reached 42 s when the amount of sizing was 12.58 g/m2 with a 96.83% decrease and a 40.00%, increase, respectively. Furthermore, the mechanical properties were optimal when the amount of sizing was about 8 g/m2. AKD/NCC emulsion acted as a good reinforcing agent in surface-sized paper. © 2015 Elsevier Ltd.

The impact of temperature on the delignification rate is higher than on the cellulose degradation rate at the initial stage of oxygen delignification, and there is little difference of the impacts on the delignification rate and cellulose degradation rate at the end of oxygen delignification process. The influence of oxygen process on delignification rate is lower than cellulose degradation rate at the initial stage of oxygen delignification, there is little difference of the influences on both delignification and cellulose degradation rates. The impacts of 0H~ concentration on the delignification rate and cellulose degradation rate are similar, however, its impact on cellulose degradation rate is higher at the end of delignification process. Base on this, three different designs of delignification process are analyzed and compared. The factors which impact the oxygen delignification efficiency are not only limited to these in the actual production. The pulp carried over to oxygen delignification stage is also very important.

The impact of different types of small particle size SB latex on the properties of top coating of the art paper using the coatings formulation with 100% GCC and the physical properties of the coated paper were studied in this paper. The results showed that compared to the coatings formulations containing clay, the formulation of GCC maintained a lower high shear viscosity. In addition, it provided the coated paper good gloss and printability. ©, 2015, China Technical Association of Paper Industry. All right reserved. Source
