Development of high volume rice husk ash alumino silicate composites

International Journal of Minerals,Metallurgy and Materials 2010年第5期17卷 654-659页

作者： Ubolluk Rattanasak Prinya Chindaprasirt prasert Suwanvitaya Department of Chemistry and Center for Innovation in Chemistry Faculty of Sciences Burapha University Department of Civil Engineering Faculty of Engineering Khon Kaen University Department of Civil Engineering Faculty of Engineering Kasetsart University

The development of high volume rice husk ash （RhA） alumino silicate composites （ASC） was studied. RhA was used as the source of silica and aluminium in the ASC. The mass ratios of RhA：Al（Oh）3 of 70：30 to 99：1 were tested. The results indicate that the obtained ASC mortars are not stable and disintegrate in water. Boric acid was introduced to the mixture to overcome this problem. Stable ASC mortars with high RhA：Al（Oh）3 mass ratios of 90：10 to 97.5：2.5 were obtained with the use of boric acid and 115oC curing. The compressive strength of the mortar of 20 MPa was gained. The immersion test indicates that high volume RhA ASC mortars show good resistance in 3vol% h2SO4 solution, but is slightly less durable in 5wt% MgSO4 solution.

本研究使用原位X射线衍射(in-situ XRD)技术,对Na/Fe_(2)O_(3)样品的还原及活化过程进行了原位表征,探究了Na含量、预处理气氛对Fe基催化剂物相的影响,并研究了铁氧化合物与铁碳化合物在CO_(2)加氢过程中的协同作用。结合h_(2)-TPR、CO+h_(2)-TPSR-MS手段对催化剂样品进行了物化性质表征。结果表明,还原气氛为h_(2)时,Na助剂修饰会抑制Fe_(2)O_(3)催化剂还原;然而还原气氛为合成气(CO/h_(2)=1∶2)时,适量Na助剂会降低还原和活化温度,提高碳化铁含量。采用h_(2)和合成气分别对Fe基催化剂进行还原处理,低碳烯烃选择性由0.3%提高至20.2%,CO_(2)转化率由7.3%提升至25.8%;与纯Fe_(2)O_(3)相比,Na修饰后催化剂Fe_(5)C_(2)含量从8.5%提高到38.4%,C_(5+)选择性由7.8%提升至37.0%,Ch_(4)选择性从43.2%降至14.9%。催化剂通过调节还原气氛和Na助剂修饰量有效调控Fe_(3)O_(4)和Fe_(5)C_(2)物相比例,提升Fe基催化剂CO_(2)加氢活性和产物选择性。

AIM: To characterise neuraminidase(NA) substrate specificity of avian influenza h5N1 strains from humans and birds comparing to seasonal influenza ***: Avian influenza h5N1 strains from humans and birds were recruited for characterising their NA substrate specificity by using a modified commercial fluorescence Amplex Red assay. This method can identify the preference of α2,6-linked sialic acid or α2,3-linked sialic acid. Moreover, to avoid the bias of input virus, reverse genetic virus using NA gene from human isolated h5N1 were generated and used to compare with the seasonal influenza virus. Lastly, the substrate specificity profile was further confirmed by high-performance liquid chromatography(hPLC) analysis of the enzymatic product. RESULTS: The h5N1 NA showed higher activity on α2,3-linked sialic acid than α2,6-linked(P he NA activity between the h5N1 and seasonal influenza viruses, reverse genetic viruses carrying the NA of h5N1 viruses and NA from a seasonal h3N2 virus was generated. In these reverse genetic viruses, the NA activity of the h5N1 showed markedly higher activity against α2,3-linked sialic acid than that of the h3N2 virus, whereas the activities on α2,6-linkage were comparable. Interestingly, NA from an h5N1 human isolate that was previously shown to have heamagglutinin(hA) with dual specificity showed reduced activity on α2,3-linkage. To confirm the substrate specificity profile, hPLC analytic of enzymatic product was performed. Similar to Amplex red assay, h5N1 virus showed abundant preference on α2,3-linked sialic ***: h5N1 virus maintains the avian specific NA and NA changes may be needed to accompany changes in hA receptor preference for the viral adaptation to humans.
