In this study the different finesses degree of the pulverized Eupatorium Adenophorum (EA) was evaluated as potential raw materials for the low-cost hydrogels whose the swelling behaviors were compared and studied at the same graft-copolymerization condition.
Based on our preliminary research of chemical-composition relatively with Eupatorium adenophorum, it was found that EA contains 67.2wt% holocellulose and 17.3wt% lignin, both of which are known as native polymers and have large quantities of hydroxyl groups playing a significant role in graft copolymerization with chemical monomers for absorbent materials.

Influence of Catalysts with Different Templates on Direct Decomposition of NO in Cement Kiln Exhaust Yanling Gana, Suping Cuib*, Hongxia Guoc, Xiaoyu Mad and Yali Wange Materials Science and Engineering, Beijing University of Technology, No.100 Pingleyuan, Chaoyang District, Beijing, 100124, China aganyanling1102@126.com, bcuisuping@bjut.edu.cn, chxguo@bjut.edu.cn, chxguo@bjut.edu.cn, dmaxiaoyu@bjut.edu.cn, ewangyali1978@bjut.edu.cn Keywords: Template; porous materials; NO decomposition; catalysts Abstract.
The NO direct decomposition rate of porous catalyst materials with different templates was determined by infrared spectrometer.
The main source of nitrogen oxides is the burning of chemical raw materials [2,3], mainly including motor vehicle exhaust, nitrogen oxides from industrial production and so on.
Different kinds of templates were used to make the copper exchange porous molecular sieve materials, and the effect of different templates on the catalytic decomposition of NO was studied in this paper.
All materials were dissolved in aqueous solution.

The slag and other porous materials can be also utilized as fillers.
Materials and Samples Materials properties of studied plasters according to the technical data sheets are shown in Table 1 [4, 5].
Materials properties according to the technical data sheets.
Total porosity of both materials is really high as it can be seen in the Table 2.
The water vapor diffusion coefficient is similar for both measured materials.

The material was ST14, thickness was 0.8mm, and the overall dimension was 1000×600mm.
