| 1 | A readily monitored and controllable hydrothermal system for the facile,cost-effective transformation of FGD gypsum to calcium sulfate hemihydrate whiskers显示文摘The controllable transformation of flue gas desulfurization(FGD)gypsum to calcium sulfate hemihydrate(HH)whiskers under facile,readily monitored,and cost-effective hydrothermal conditions could play a vital role in the preparation of high quality HH whiskers and improve our understanding of the transformation process.This work assessed the conversion of FGD gypsum to HH whiskers in 5×10^(-4)mol/L H_(2)SO_(4)and 1.5 wt%CuCl_(2)at 120℃while determining the effects of temperature as well as H_(2)SO_(4)and CuCl_(2)concentrations on transformation kinetics.The preparation of HH whiskers was found to involve a solution-mediated transformation from the dihydrate(DH)to theα-HH.This transition was determined to proceed via a dissolution crystallization mechanism,the rate of which was controlled by nucleation and growth of the HH whiskers.An autocatalytic kinetic model was established based on variations in the HH whiskers mole fraction over time,and this model accurately fit the experimental data with R2=0.990.Increasing the temperature or H_(2)SO_(4)concentration accelerated the transformation by modifying the super-saturation and water activity in the reaction solution,while increasing the CuCl_(2)concentration had the opposite effect.The hydrothermal conditions had an important effect on the transformation from FGD gypsum to HH whiskers. | Bolun Cao Xiao Wang Xiaoting Zhang Biao Jin Zhuoyue Xu Xueping Liu Wei Zhang Liushuan Yang | 2021 | Particuology2021，19，1： | 8 |

| 3 | Effects of soaking process on arsenic and other mineral elements in brown rice显示文摘One of the main food crops in the world,rice can accumulate high levels of arsenic from flooded paddy soils,which seriously threatens human health.Soaking,a common processing method for brown rice products,especially for brown rice noodles,was investigated in this study.Japonica rice(Dao Hua Xiang No.2)and Indica rice(Ye Xiang You No.3)were selected for studying the effects of soaking on arsenic concentrations,species,and distributions.Results revealed that soaking can efficiently remove arsenic in these two rice varieties,and the main part of removal is endosperm with the maximal rate of about 40%.Inorganic arsenic(I-As)(about 85%)is the main species of arsenic reduction.Meanwhile,the variations of four other elements(i.e.,Mg,Ca,Zn,and Fe)were analyzed.Collectively,the findings of this study indicate that soaking can efficiently remove arsenic in brown rice under controlled soaking conditions,which thereby reduces the arsenic intake for brown rice customers. | Fan Zhang Fengying Gu Huili Yan Zhenyan He Bolun Wang Hao Liu Tingting Yang Feng Wang | 2020 | Food Science and Human Wellness2020，9，2： | 5 |
| 4 | Chemical looping gasification of maceral from low-rank coal: Products distribution and kinetic analysis on vitrinite显示文摘The product distribution and kinetic analysis of low-rank coal vitrinite were investigated during the chemical looping gasification(CLG)process.The acid washing method was used to treat low-rank coal,and the density gradient centrifugation method was adopted to obtain the coal macerals.By combining thermogravimetric analysis and online mass spectrometry,the influence of the heating rate and oxygen carrier(Fe2O3)blending ratio on product distribution was discussed.The macroscopic kinetic parameters were solved by the Kissinger-Akahira-Sunose(KAS)method,and the main gaseous product formation kinetic parameters were solved by the iso-conversion method.The results of vitrinite during slow heating chemical looping gasification showed that the main weight loss interval was 400–600℃,and the solid yield of sample vitrinite-Fe-10 at different heating rates was 64.30%–69.67%.When b=20℃·min^(-1),the maximum decomposition rate of vitrinite-Fe-10 was 0.312%min1.The addition of Fe2O_(3)reduced the maximum decomposition rate,but by comparing the chemical looping conversion characteristic index,it could be inferred that the chemical looping gasification of vitrinite might produce volatile substances higher than the pyrolysis process of vitrinite alone.The average activation energy of the reaction was significantly reduced during chemical looping gasification of vitrinite,which was lower than the average activation energy of 448.69 kJ·mol^(-1) during the pyrolysis process of vitrinite alone.The gaseous products were mainly CO and CO_(2).When the heating rate was 10℃·min^(-1),the highest activation energy for CH4 formation was 21.353 kJ·mol^(-1),and the lowest activation energy for CO formation was 9.7333 kJ·mol^(-1).This study provides basic data for exploring coal chemical looping gasification mechanism and reactor design by studying the chemical looping gasification process of coal macerals。 | Bo Zhang Bolun Yang Wei Guo Song Wu Jie Zhang Zhiqiang Wu | 2021 | Chinese Journal of Chemical Engineering2021，34，8： | 2 |
