The sample was characterized by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). The results show that the crystal phase of the sample is composed of anatase and montmorillonite. The microstructure of the sample is still layered structure, in which anatase particles lie in the interlayer space. Furthermore, the XRD results indicate that the interlayer distance of crystal plane (001) of the montmorillonite left-shift obviously. In other words, its interlayer distance increases obviously. The adsorptive ability of the sample was tested with industry wastewater, which containing Pb2+. The results indicate that the adsorptive rate of the sample for lead (II) cation is 100% almost. The Ti-pillared montmorillonite absorbed Pb2+ saturatedly was impregnated into 3 mol/L nitric acid solution for 2 h to dissolve the lead cation, then it was rinsed by deionized water for three times and dried at 120 °C overnight. The sample impregnated by nitric acid solution was used to treat Pb2+ containing industry wastewater again.

Studies on these samples include the determination of chemical composition by ICP, the analysis of mineralogical construction by XRD, orthogonal experiments of iron leaching by acids and decarburization by calcination. Results show that the chemical compositions of three samples are very close to the kaolinite and their mass ratios of SiO2 to Al2O3 are all about 1.4:1. The major crystalline phase presented in the coal gangue is kaolinite, while an obvious band of amorphous materials are found in others since they are combustion products, but none of them is in exception of layer structure observed though SEM. Orthogonal experiments of iron leaching by acids reveal that the maximal iron leaching rate and product-calcined whiteness of the coal gangue are 63.59% and 68.54% respectively. For that of the slag of CFB, they are 39.74% and 40.55%, while for that of the washed fly ash, they are 31.58% and 45.92%. Thus, it can be inferred that this coal gangue can better fulfill the preparation of high-quality calcined kaolin.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"7 1","pages":"730-734"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86904924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HS is a typical mesoporous material and has smaller surface area and bigger average pore diameter compared with the PAC. PAC has the well-developed interstitial structure, while HS's surface holes are shallow. The structural difference between the two adsorbents determined the different adsorption/desorption performance in recovery of oil vapor. PAC has the bigger adsorption amount and faster adsorption rate of oil vapor, while the oil vapor adsorbed in HS is much easier to be desorbed. The mixture of PAC and HS represented both the properties of fast adsorption rate and perfect desorption performance which can improve the life and efficiency of the recovery system at the same time. The adsorption amount of adsorbent increased with the increase of inlet concentration and decreased with the increase of inlet velocity of oil vapor.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"3 1","pages":"554-557"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87864956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, deposition coefficient, defined as the fraction of volatile and gases deposited on the char due to the secondary reaction, is introduced to modify the kinetics model in literatures. The effects of heating rates, heating temperatures and deposition coefficients on pyrolysis products distribution under non-isothermal and isothermal conditions are discussed. The investigation based on the modified model shows that the deposition coefficient affects the secondary reaction products distribution significantly. When the deposition coefficient increases, the generation rate and the concentration of char increase and the volatile and gases in secondary reaction decrease. The results indicate that primary reaction plays a dominant role in volatile and gases generation and secondary reaction plays a dominant role in char generation. The work in this paper provides useful information for optimal design of biomass gasifiers and reactors.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"48 1","pages":"331-334"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76500824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
