Zeolites have been widely used in the adsorption and removal of volatile organic compounds (VOCs). In this study, we investigated the adsorption properties of 9 commercial zeolites and MCM-41 mesoporous silica for pxylene. And then zeolites with hierarchical structures were prepared by alkali (0.1-0.8 mol center dot L-1 mixed alkali solution) modif...

The endophytic microbiome uses mechanisms such as the secretion of diffusible antibiotic molecules, synthesis and release of volatile organic compounds, and/or toxins to protect plants. The aim of this research was to study the volatile organic compounds (VOCs) profile as well as the diffusible secondary metabolites produced and released by endophy...

Flavor and taste attributes of fruits varied by different preservatives treatments. Changes in sugars, organic acids, amino acids as well as volatiles of strawberries treated with 1-methylcyclopropene (1-MCP) and/or chlorine dioxide (ClO2) were evaluated during storage period in this study. Our results revealed that the decreases of tartaric acid, ...
Porous ceramic membranes (PCMs) are considered as an efficient hot gas filtration material in industrial systems. Functionalization of the PCMs with high-efficiency catalysts for the abatement of volatile organic compounds (VOCs) during dust elimination is a promising way to purify the industrial exhaust gases. In this work, we prepared PCMs (poros...
Malodorous aldehyde gases, such as n-butyraldehyde, are not only problematic volatile organic compound pollutants but also have offensive odors with a very low olfactory threshold (ppb), which can reduce the quality of daily life even at a very low concentration (0.1-10 ppm). Materials such as activated carbon (AC), metal-organic frameworks (MOFs),...
Herein, a series of monolithic Mn/Ce-based catalyst of ceramic membranes (CMs) were prepared through impregnation method for volatile organic compounds (VOCs) removal. The porous fibrous CMs with a sinter-locked network structure were fabricated by molding method in a feasible sintering process. Then, the catalytic CMs were systematically analyzed ...
采用传统VOCs蓄热催化燃烧装置可以实现蓄换热、VOCs催化燃烧的目的,但该装备存在着不能完全连续化、电控要求高、制造成本高、占地面积大等缺点。为解决上述问题,研制出连续式催化燃烧装备。本文先对装备背景进行讲述,重点讨论连续催化燃烧装备原理、结构以及关键结构技术。
In this paper, a series of NiAl hydrotalcite-like compounds (HTLCs) were prepared by the urea-decomposition method. Removal of carbonyl sulfide (COS) and methyl mercaptan (CH4S) over the hydrotalcite-derived oxides (HTO) at low temperature was studied. The Ni3Al-HTO exhibited higher catalytic activities than Ni3Al mixed oxides prepared by physical ...
A co-current flow rotating packed bed was applied to remove volatile organic compounds (VOCs) by sodium hypochlorite (NaClO) and surfactant (sodium dodecyl benzene sulfonate, SDBS) from air stream. Xylene was used as a model VOC herein. The effect of pH, concentration of NaClO and SDBS solution, liquid flow rate, gas flow rate and rotational speed ...
The design and synthesis of highly active non-noble metal oxide catalysts, such as transition- and rare-earth-metal oxides, have attracted significant attention because of their high efficiency and low cost and the resultant potential applications for the degradation of volatile organic compounds (VOCs). The structure-activity relationships have b...
