| 1 | Breakthrough CO_2 adsorption in bio-based activated carbons显示文摘In this work, the effects of different methods of activation on CO2 adsorption performance of activated carbon were studied. Activated carbons were prepared from biochar, obtained from fast pyrolysis of white wood, using three different activation methods of steam activation, CO2 activation and Potassium hydroxide(KOH) activation. CO2 adsorption behavior of the produced activated carbons was studied in a fixed-bed reactor set-up at atmospheric pressure, temperature range of 25–65°C and inlet CO2 concentration range of10–30 mol% in He to determine the effects of the surface area, porosity and surface chemistry on adsorption capacity of the samples. Characterization of the micropore and mesopore texture was carried out using N2 and CO2 adsorption at 77 and 273 K, respectively.Central composite design was used to evaluate the combined effects of temperature and concentration of CO2 on the adsorption behavior of the adsorbents. The KOH activated carbon with a total micropore volume of 0.62 cm3/g and surface area of 1400 m2/g had the highest CO2 adsorption capacity of 1.8 mol/kg due to its microporous structure and high surface area under the optimized experimental conditions of 30 mol% CO2 and 25°C. The performance of the adsorbents in multi-cyclic adsorption process was also assessed and the adsorption capacity of KOH and CO2 activated carbons remained remarkably stable after50 cycles with low temperature(160°C) regeneration. | Sepideh Shahkarami Ramin Azargohar Ajay K.Dalai Jafar Soltan | 2015 | Journal of Environmental Sciences2015，27，8： | 2 |
| 2 | Room temperature oxidation of acetone by ozone over alumina-supported manganese and cobalt mixed oxides显示文摘Volatile organic compounds(VOCs)are among the major sources of air pollution.Catalytic ozonation is an efficient process for removing VOCs at lower reaction temperature compared to catalytic oxidation.In this study,a series of alumina supported single and mixed manganese and cobalt oxides catalysts were used for ozonation of acetone at room temperature.The influence of augmenting the single Mn and Co catalysts were investigated on the performance and structure of the catalyst.The manganese and cobalt single and mixed oxides catalysts of the formula Mnl0%-CoX and Co10%-MnX(where X=0,2.5%,5%,or 10%)were prepared.It was found that addition of Mn and Co at lower loading levels(2.5%or 5%)to single metal oxide catalysts enhanced the catalytic activity.The mixed oxides catalysts of(Mnl0%-Co2.5%)and(Mn10%-Co5%)led to acetone conversion of about 84%.It is concluded that lower oxidation state of the secondary metal improves ozone decomposition and oxidation of acetone. | Mehraneh Ghavami Mostafa Aghbolaghy Jafar Soltan Ning Chen | 2020 | Frontiers of Chemical Science and Engineering2020，14，6： | 2 |
| 3 | Experimental approaches and analytical technique for determining heavy metals in fallen dust at ferrosilicon production factory in Edfu, Aswan,Egypt显示文摘In this study aimed to evaluate the pollution extent of metals and nonmetals inside and outside the ferrosilicon production factory in Edfu, Aswan, Egypt, raw materials (quartz, cokes, iron oxides), ferrosilicon alloy, silica fume, dust and suspended dust (at different sites) samples were collected from the factory, and fallen dust samples were collected from outside the factory, horizontally (at different sites and different distance and directions) and vertically (at different floors in the selected buildings). Gravimetric methods, X-ray fluorescence (XRF), flame photometer, wide range carbon determinator and atomic absorption spectroscopy tools were used for elements determination. The results indicating that the fallen dust and its element contents on southern factory walls being higher than those on eastern factory walls may be due to the nature of the dusts and effects of wind force and wind direction. Fallen dust levels in different regions outside the factory were found to be affected by the distance, direction and floors. The nature of dust samples was affected by gravity and the suspended dust in different factory units depended on the work capacity and method of handling materials by personnel in different production units. Silica fume was a complicated problem, had dangerous effect against the workers' health, and was characterized by high concentrations of SiO2(90.6%~93.6%) and heavy metals (Mn, 420.6×10-6~520.3×10-6; Fe, 2354×10-6~2685×10-6; Co, 80.7×10-6~101.6×10 6 and Ni,5.3× 10-6~6.05× 10-6). The TSP (Total Suspended Particulate) levels in all factory units were higher than the recommended air quality value (70 μg/m3) under Egyptian law. The effect of ferrosilicon factory fallen dust on the surrounding regions decreased with increasing distance between the factory and these regions. The suspended dust samples in the factory units and their components greatly exceeded national and international standards, so health and environmental criteria must be enforced on these units. | SOLTAN M.E RAGEH H.M RAGEH N.M AHMED M.E | 2005 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2005，6，8： | 2 |
