Tobermorite, an important but rare naturally mineral, could not be directly hydrothermal synthesized from it owing to its high content of Ca but low concentration of Si and Al. The selected external silicon-aluminum additives including coal fly ash (CFA), bentonite, kaolin and diatomite were solely or combined added. With the addition of 30% mass composite additive in which the ratio of quality for CFA and diatomite is 1:1, tobermorite could be synthesized most effectively in 48h at 150°C, mainly attributing to the proper element proportion adjusted by additives. Tobermorite seed added could not only promote the large formation of tobermorite, but also inhibit the production of hibschite and kaotoite. Since Ca/(Si + Al) = 1.20 and Al/(Si + Al) = 0.20, addition of 30% mass of composite additive and 3% mass of tobermorite seed would be the recommended technological parameter.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79118649","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 process of double solid solution aging treatment, the numerical values of room-mechanical properties reached the highest level. Multiple solution and aging treatment modulates morphology effectively, which can make martensite lamellas with different Berlese’s vectors merge or decompose.

As a high ethanol yield crop, sugarcane has attracted increasing industrial interest as a raw material for biofuel and the risk of heavy metal in it is negligible if the sugar produced is to be fermented into ethanol rather than by consumed. This study is to do a preliminary investigation if sugarcane is a suitable crop for phytoremediation in heavy metal polluted farmland in a context of geographic conditions in southern China, thirty-eight soil and sugarcane samples were collected in five villages in a typical agricultural county called Huangjiang which is located in the Huanjiang River Basin in Guangxi province. Sugarcane is widely cultivated in Huangjiang as one of the major economic crops, meanwhile, pollutions induced by mining and ore-extraction in this area has resulted in heavy metals entering the farmland soils. Samples collected were used to assess the correlation of the level of heavy metals in the soil, and their concentrations in roots, sections of stems and leaves. Seven heavy metals were selected in this study and the results showed that most of the toxic heavy metals intake by sugarcane accumulated in the roots, while only a small portion is transferred to the stems and leaves. The study initially outlined sugarcane as a potential candidate for phytoremediation in farmland polluted by heavy metals with economic motivate in this subtropical geographical background.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"50 1","pages":"143-154"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77850799","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}

Reliable uncertainty estimates can also be used to increase the quality of emission inventories. This paper took the emission of CH4 from the solid waste landfill in Hefei City in 2014 as an example, and employed the mass balance method to compute its emission. Monte Carlo method was used to carry out the sensitivity analysis and compute uncertainty. Through computing, 95% confidence interval of CH4 emission from landfill in Hefei City was (1.89~3.40) × 104 t. The mean value was 2.61 × 104 t with uncertainty range of –27.59%~30.27%. Among all the parameters, the decomposable proportion of DOC (DOCf ) showed the greatest impact on the emission of CH4 from the landfill and its contribution to emission result was 26.33%. Followed by the degradable organic carbon (DOC) was 26.29%, the amount of solid waste (MSW) was 13.63%, methane correction factor (MCF) was 6.93% and the proportion of methane in landfill gas (F) was 6.58%.

Though B2O3 was effective to prepare dense BT2, it, disadvantageously, tended to decrease the permittivity of BT2.

The objective of this paper is to investigate erosion-corrosion mechanisms of J55 steel and the effects of local hydrodynamic factors, in particular, the fluid flow velocity on J55 steel’s service life. A new experimental setup was developed to specifically simulate the actual hydrodynamic conditions of Huanghe (Yellow) River valley. Computational fluid dynamics (CFD) model was adopted to characterize the hydrodynamic factors, such as the flow rate, the turbulence kinetic energy and the shear stress, and their effects on the corrosion behavior of J55 steel. Corrosion morphology was analyzed. Results show that the erosion rate increased with the flow rate and the resulting corrosion pit became smaller and deeper.
