摘要 ：
Adsorption technology is considered one of the most effective methods for removing volatile organic compounds (VOCs). However, it is difficult to select the optimal activated carbon (AC) for different VOCs industries due to its various categories. To develop a comprehensive assessment system for commercial AC in typical gasoline vapor removal, 12 commercial AC (coal, shell, and wood carbon) were selected. Their physical properties, chemical characteristics and target pollutant adsorption capacity were studied. A comprehensive evaluation system was established based on the improved Analytic Hierarchy Process (AHP). The weighted of AHP method was determined by the correlation between adsorption capacity and each property indicator. The adsorption of i-pentane was influenced by the specific surface area (SSA) and alkaline functional groups of AC, with the former showing a significant positive correlation (correlation coefficient=0.853, P<0.05) and the latter showing a negative correlation (correlation coefficient=-0.845, P<0.05). Based on the average comprehensive scores, the wooden carbon performed the best, followed by the coal carbon and the shell carbon. Owing to the highest SSA (1851 m2/g) and the highest acidic functional groups (1.354 mmol/g) of the wooden carbon, the i-pentane adsorption performance (553.5 mg/g) was the best. The method we proposed can be used to rank the commercial AC based on the different aspects, which can be employed for the selection and recommendation of high-quality AC for various VOCs industries.

摘要 ：
本发明提供了一种改性赤泥基吸附剂及其制备方法和应用，涉及工业固废资源化利用技术领域。本发明先对赤泥进行酸碱改性(活化和焙烧)，使得赤泥转变为介孔材料，大大提高了赤泥的比表面积和孔容，从而显著提高了二氧化碳气体扩散与吸附性能，使得改性赤泥基吸附剂对二氧化碳的吸附容量明显增加。通过采用浸渍法在所得酸碱改性赤泥上负载MgO，提供了更多的碱性活性位点，对二氧化碳的吸附容量有明显的提高。酸碱改性赤泥对二氧化碳主要进行物理吸附，MgO提供碱性活性位点对二氧化碳进行化学吸附，实现了物理和化学吸附的协同作用，提高了对二氧化碳的吸附容量和吸附速率，在常温常压下即可实现吸附二氧化碳，二氧化碳的脱附温度低。

摘要 ：
Currently, air pollution is primarily characterized by PM2.5 and O-3. Therefore, the co-control of PM2.5 and O-3 has become an important task of atmosphere pollution prevention and control in China. However, few studies have been conducted on the emissions from vapor recovery and processes, which is an important source of VOCs. This paper analyzed the VOC emissions of three vapor process technologies in service stations and first proposed key pollutants for priority control based on the coordinated reactivity of O-3 and SOA. The concentration of VOCs emitted from the vapor processor was 3.14-9.95 g m(-3), compared to 631.2-717.8 g m(-3) for uncontrolled vapor. Alkanes, alkenes, and halocarbons accounted for a high proportion of the vapor both before and after control. Among the emissions, i-pentane, n-butane, and i-butane were the most abundant species. Then, the species of OFP and SOAP were calculated through the maximum incremental reactivity (MIR) and fractional aerosol coefficient (FAC). The average source reactivity (SR) value of the VOC emissions from three service stations was 1.9 g g(-1), while the OFP ranged from 8.2 to 13.9 g m(-3) and SOAP ranged from 0.18 to 0.36 g m(-3). By considering the coordinated chemical reactivity of O-3 and SOA, a comprehensive control index (CCI) was proposed for the control of key pollutant species that have multiplier effects on environment. For adsorption, trans-2-butene and p-xylene were the key co-control pollutants, while toluene and trans-2-butene were the most important for membrane and condensation + membrane control. A 50% emission reduction of the top two key species that emission account for 4.3% averagely will reduce O-3 by 18.4% and SOA by 17.9%.

摘要 ：
Cubic Cu2O micro/nanocrystals were successfully synthesized by liquid-phase reduction using copper salt of CuSO4 or CuCl2.2H2O, and glucose or ascorbic acid as reducing agent, respectively. The activity of the catalysts was evaluated by light-off curves of CO self-sustained catalytic combustion via temperature-programmed oxidation of CO (CO-TPO), with the results showing the activity of catalysts following the order of Cu2O-ClGLU > Cu2O-S-GLU > Cu2O-S-AA > Cu2O-Cl-AA, (Cl denotes CuCl2.2H2O, GLU denotes glucose, S denotes CuSO4 and AA denotes ascorbic acid, respectively), corresponding to the ignition temperature of 109 degrees C, 122 degrees C, 137 degrees C and 186 degrees C, respectively. The crystal structure, elemental valence, morphology and redox property of the prepared catalysts were analyzed by using various characterization techniques. Combined with in situ infrared spectrum, the CO self-sustained catalytic combustion over Cu2O catalysts mainly follows the Mars-van-Krevelen (M-v-K) mechanism: the adsorbed and activated CO reacts with lattice oxygen to yield CO2 and oxygen vacancy, and then the oxygen vacancy can be replenished by gaseous oxygen. Combined with catalytic performance of high-concentration CO, it is found that the catalysts prepared using glucose as reducing agent are more angular compared with ascorbic acid. The Cu2O-Cl-GLU synthesized with glucose and CuCl2.2H2O exhibits the best catalytic activity among all the catalysts tested, attributing to its more obvious edge and rough crystal surface. The unique structure of Cu2O-Cl-GLU leads to the high exposure rate and coordination unsaturation of atoms on the cubic Cu2O micro/nanocrystals that can improve the ability of activating gaseous O2 and low temperature reducibility, and consequently facilitating the catalytic activity.

摘要 ：
Non-thermal plasma (NTP) is considered to be a promising technology for the removal of volatile organic compounds; however, its application is limited by low CO2 selectivity and undesirable by-products. To overcome these issues, this paper discusses the degradation of chlorobenzene (CB) in systems of NTP coupled with catalysts, and the influence of catalyst locations in the NTP was investigated. In addition, the interaction between plasma and catalyst was also explored. The results indicated that the degradability of CB was remarkably improved through the combination of NTP with catalysts, and the formation of ozone was effectively inhibited. The degradation efficiency increased from 33.9% to 79.6% at 14 kV in the NTP-catalytic system, while the ozone concentration decreased from 437 to 237 mg m(-3), and the degradation efficiency of in plasma catalysis (IPC) systems was superior to that of the post plasma catalysis system, while the inhibition ability of ozone exhibited an opposing trend. In the IPC system, the degradation efficiency was 87.7% at 14 kV, while the ozone concentration was 151 mg m(-3). Besides, the plasma did not destroy the pore structure and crystal structure of the catalyst, but affected the surface morphology and redox performance of the catalyst. Thus, NTP coupled catalytic system could improve the degradation performance of CB. Furthermore, the plasma discharge characteristics played a major role in the NTP synergistic catalytic degradation of CB. Finally, based on the experiment analysis results, the general reaction mechanism of CB degradation in an IPC reaction system was proposed.
