the core shell internal nanostructure of soot a criterion to model soot maturity
Carbon, 2016Co-Authors: Mohammad Reza Kholghy, Armin Veshkini, Murray J ThomsonAbstract:Abstract A novel model called Surface Shell Formation (SSF) is developed which predicts soot maturity based on the equilibrium nanostructure of poly aromatic hydrocarbons (PAHs) inside soot primary particles. The characteristic isotropic core-graphitic shell internal nanostructure of soot primary particles is used to distinguish nascent from mature soot primary particles. A new sectional soot model is developed to track particle Hydrogen to Carbon (H/C) Ratio and the growth in the molecular weight of PAHs inside soot primary particles. An independent Arrhenius term describes particle dehydrogenation/carbonization. It is shown that soot maturity depends on both particle size and H/C Ratio. Graphitic shell formation in mature soot particles is related to the surface PAHs that change configuRation from edge on surface for nascent soot to face on surface for mature soot particles. The new model is validated against experimental data for laminar premixed, partially premixed and diffusion flames. The SSF model addresses the two major limitations of the current soot modeling approaches. First, it predicts H/C Ratio of soot particles by considering soot carbonization. Second, it distinguishes nascent soot from mature soot primary particles based on the internal nanostructure of soot primary particles and the presence of the graphitic shell.

characterization and non isothermal decomposition kinetics of some turkish bituminous coals by thermal analysis
Fuel Processing Technology, 2004Co-Authors: Sait Kizgut, Serdar YilmazAbstract:Abstract The thermal behavior of five bituminous coal samples was investigated in non-isothermal condition by thermal analysis. The integral method was used in the analysis of TGA data in order to determine the decomposition kinetics. The main region of the sample's weight loss, arising from the conversion of organic matter to gas, occurred within the temperature range 400–600 °C. The thermal parameters derived from TG and DTG curves were correlated with petrographic, proximate and ultimate analyses data. The results indicated that H/C Ratio, fuel Ratio, mean vitrinite reflectance and petrofactor could be qualitatively used in the prediction of the TG and burning behavior of various rank bituminous coals.

effect of retorting temperature on product yield and characteristics of non condensable gases and shale oil obtained by retorting huadian oil shales
Fuel Processing Technology, 2014Co-Authors: Sha Wang, Xiumin Jiang, Xiangxin Han, Jianhui TongAbstract:Abstract Oil shale samples from Huadian were retorted in a stainless-steel cylindrical retort under argon atmosphere to determine retorting temperature effect on the product yield and characteristics of shale oil and non-condensable gases produced. Increasing temperature from 430 °C to 520 °C improved both oil and gas yields, but reduced the oil/gas yield Ratio. Raising temperature increased nitrogen content in the derived shale oil and decreased the atomic H/C Ratio and oxygen content, but had no significant effect on the sulfur content. It was also noticed that the boiling point of shale oil generated at 490 °C was lowest, and the shale oils obtained at 430 °C and 460 °C showed similar boiling point distributions. The produced shale oils had similar atomic H/C Ratio as well as higher light oil content compared to crude oils produced in China, and could be classified as sweet and high-nitrogen oil in terms of the classification method of crude oil. The oil derived at 490 °C contained the lowest amount of saturates and the highest amount of aromatics, asphaltenes and non-hydrocarbons. C 1 –C 4 hydrocarbon gas contents rose with increasing temperature. Higher ethene/ethane, propene/propane, butene/butane and alkene/alkane Ratios obtained at higher temperature were linked to secondary cracking reactions.
