摘要 ：
为了有效控制煤尘大气污染和解决农业废弃物再利用的问题,以农业废弃物为原料制备环保抑尘剂并应用于煤尘控制,实现以废治污的目的.该抑尘剂以秸秆酶解液为主要原料,考察了辅料粘结剂、保湿剂和表面活性剂对抑尘剂性能的影响.研究中通过单因素实验确定出粘结剂瓜尔豆胶、阴离子表面活性剂十二烷基硫酸钠(K 12)和保湿剂乳酸钠的比例范围,并通过正交实验的方法优化了抑尘剂配方,所制得的抑尘剂在黏度和溶液的润湿性上可以表现出更优异的抑尘性能,优化配方后抑尘剂的黏度为5.8 mPa?s、表面张力为31.20 mN/m、接触角为15.2°,具有较好的润湿性能;在8 m/s的模拟风速条件下,2 h内可保持100％的抑尘效率,可以实现有效抑制煤尘的作用.煤场实际应用结果表明,使用抑尘剂后可使煤场的PM10浓度由145.2 mg/m3降至环境背景浓度,可以达到有效抑制风力扬尘的效果.

摘要 ：
In order to reduce the dust pollution caused by the coal mining process, a novel composite environmental dust suppressant for coal dust control was synthesized by corn straw, sodium carboxymethyl cellulose (CMC), and additives. This study focused on the preparation conditions of the dust suppressant, and the performances of which were investigated systematically. Response surface method (RSM) was used to optimize the raw material formulation and preparation parameters. The optimum mass ratio of straw, CMC, and alkali of the dust suppression was 65:20:15 (m/m), which was prepared under the conditions of the reaction time being 1.5 h and the rotation speed being 300 r/min. The pH of the dust suppressant was 8.0, and the state of which was suspension. Additives were benefited to enhance the suppressant performance, and the surface tension and the contact angle could decrease to 32.4 mN/m and 32.0 degrees. The suppressant has a maximum viscosity of 363.6 mPa center dot s, and the compressive strength could be up to 200 kPa. The hygroscopic rate could reach more than 4%. The wind erosion resistance could be up to 99 % at the wind speed of 14 m/s. After spraying the dust suppressant, the gap between particles was filled with dust suppressant, and the adjacent particles were bound by strong mechanical action.

摘要 ：
Rare earth metals are strategic resources with potential applications in optics, metallurgy and catalysis. In recent years, single-atom site catalysts (SASCs) have attracted increasing attention owing to their 100% atom efficiency and unique catalytic performances. Over the past decade, rare earth elements, including rare earth metals and their oxides, have shown great potential in SASCs. However, systematic analyses of data are still handful. In this mini-review, the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed. A particular focus was paid to the synthetic strategies, characterization of rare earth-containing SASCs, and applications as catalysis supports, promoters and active sites. Current issues faced by rare-earth metals and their oxides in SASCs, as well as future prospects were also provided. (C) 2020 Chinese Society of Rare Earths. Published by Elsevier B.V.

摘要 ：
In this paper, the effect of organic sulfur on the catalytic oxidation of toluene was explored. It was found that the low concentration of organic sulfur could cause rapid deactivation of the catalyst, and the activity of the catalyst could be restored to 100% after stopping the application of sulfur. The sulfation modification could significantly improve the organic sulfur resistance of the catalyst by changing the support and the sulfation modification of the support. There was a large amount of carbon deposition and a small amount of S-containing substances on the catalyst surface after the introduction of organic sulfur through the methods of TG, BET, FTIR, SEM (Mapping) and XPS. Then, through in-situ DRIFT and CH3SH-TPD, it was found that sulfation modification could inhibit the adsorption of organic sulfur on the catalyst surface and reduce the competitive adsorption. The decrease of catalyst efficiency due to the presence of organic sulfur in the reaction gas during VOCs catalytic oxidation is mainly due to the competitive adsorption of organic sulfur and VOCs molecules, and the temperature of VOCs catalytic oxidation of organic sulfur. Some polyhydrocarbons, ethyl sulfide, dimethyl sulfoxide and other substances were produced by incomplete oxidation, which covered the surface of the catalyst due to adsorption or deposition, resulting in catalyst poisoning.

摘要 ：
Ru/TiO2 and Ru-Ce/TiO2 catalysts were prepared by the equal-volume impregnation method to test their catalytic oxidation of chlorobenzene(CB), with the aim to investigate the effect of Ce addition on the redox capacity of the catalysts under the premise of reducing the content of noble metals. It was found that the introduction of Ce conserved the high catalytic efficiency of the catalyst while reducing the content of noble metal, and the catalysis of CB was greatly improved at low temperatures. Compared with the 0.4Ru/TiO2 catalyst, the T-10 and T-90 of the 0.4Ru-1.0Ce/TiO2 catalyst decreased by 50 degrees C and 60 degrees C respectively. It presented high reaction rate at 170. with an increase from 1.21 x 10(-8) mol/min.m(2) for the 0.4Ru/TiO2 catalyst to 10.45 x 10(-8) mol/min.m(2), making it even better than the 2.0Ru/TiO2 catalyst. The structure and morphology of the Ru/TiO2 catalyst did not change with the Ce doping and the mesoporous structure of the catalysts was maintained. CeO2 can not only store and release oxygen, but also improve the activity and dispersion of precious metal loaded. The formation of Ru-O-Ce under the interaction between CeO2 and Ru species promoted electron transfer and improved the mobility of surface oxygen, thus forming RuOx with higher valance. The introduction of Ce improved the yield of COx and selectivity towards inorganic chlorine (HCl and Cl-2) and prevented the catalyst from producing more chlorinated by-products, thus greatly reducing the chance of producing more toxic dioxins.

摘要 ：
In order to reduce process complexity and manufacturing difficulty, we proposed to use a single air distribution plate to guide the flow and achieve uniform air distribution. We established a three-dimensional model with a size ratio of 1:1 to simulation flow pattern. The optimization results revealed that it is feasible to implement our assumption. After the asterisk plate's optimization, the area uniformity index in the catalytic section was maintained above 0.92 with a maximum value of 0.95, the relative standard deviation was lower than 0.2, and the minimum value was 0.123; and the pressure drop was less than 3.00 Pa, which is in line with the actual use requirements. Among them, Asterisk I with a 30 mm thickness and 15 mm right shift has the best optimization effect. (c) 2021 American Society of Civil Engineers.

摘要 ：
低温等离子体协同催化降解甲苯过程中,在降解污染物的同时活性氧原子聚合生成臭氧。本文研究比较了不同催化剂、放电能量水平、催化段长度和气速条件下的臭氧浓度变化和甲苯降解情况,探究了低温等离子体协同催化降解甲苯过程中臭氧的生成情况。研究表明,将7.5%Mn/堇青石催化剂置于放电区时能有效抑制臭氧生成,促进甲苯降解,提高系统能效,臭氧最高浓度相比无催化剂时降低63.32mg/m~3;而0.2%Pd-0.3%Ce/堇青石催化剂对甲苯降解和抑制臭氧的性能较差。随着系统能量水平的提高,甲苯降解率和臭氧生成浓度逐渐升高。臭氧生成浓度与催化段长度呈正相关关系,与气速的关系则相反。在不同的外加电压条件下,臭氧生成...
