"Destruction of volatile organic compounds by the optimal multivariable control of a catalytic reverse flow reactor", Summary This paper aims to compare 2 optimal control laws for a catalytic reverse flow reactor (RFR), which topic has not often been tackled. The RFR aims to destruct volatile organic compounds (VOCs), which are noxious products and are the source of a lot of problems: pollution...

China is suffering from serious water and soil pollution, especially in the North China Plain. This work investigated semi-volatile organic compounds (SVOCs) in surface water, groundwater and soil within a chemical industrial park in Eastern China, for which the volatile organic compound (VOC) results have been previously reported. A total of 20 samples were collected from the field, and analyz...

This study assessed subjective symptoms related to indoor concentrations of chemicals among residents in a housing estate in Dalian, China, where indoor air pollution by interior decoration materials has recently become a major health problem. Fifty-nine males and 50 females were surveyed for their symptoms related to sick building syndrome. Formaldehyde (HCHO), NO2, and volatile organic compou...

[1] A three-dimensional photochemical model has been used to interpret aircraft measurements from the Atmospheric Pollution Over the Paris Area campaign near Paris, with special attention to measurements that are related to predicted O3-NOx-volatile organic compound (VOC) sensitivity. The model (CHIMERE) includes a representation of ozone formation over Europe and a more detailed spatial repres...

The accurate identification of ozone (O3) production sensitivity is central to developing O3 pollution control policies. It determined by the relative ratio radical loss total primary production. However, such losses in traditional analysis typically rely on nitrogen oxide (NOx) sinks while ignoring particle uptake (collisions between compounds gas phase and condensed phases that result irrever...

To understand the characteristics and environmental effects of volatile organic compounds (VOCs) in a typical medium-sized city China, manual measurements including 56 species nonmethane hydrocarbons (NMHCs) were taken at three urban suburban sites Huai’an from April to September 2019, automatic 106 VOCs center May August 2019. Spatial temporal VOC concentrations analyzed. Positive matrix facto...

Vehicle emissions have become a significant source of air pollution in urban cities, especially China. Mobile sources account for 45% local fine particle the Chinese capital Beijing. The Beijing–Tianjin–Hebei (BTH) area, one China’s most representative clusters, is suffering from severe pollution. With rapid growth vehicle ownership past two decades, China also undergone great changes under var...

Volatile organic compounds (VOCs) are part of the large hydrocarbon family, a vast array of aliphatic, aromatic hydrocarbons, their halogenated derivatives, alcohols, ketones and aldehydes. VOCs have a property of conversion into vapour or gas without any chemical change. They are highly reactive hydrocarbons and participate in atmospheric photochemical reactions. Some of them have negligible p...

People spend most of their time indoors. The volatile organic compounds (VOCs) in indoor air represented by toluene inevitably affect people's health. Activated carbon can effectively reduce VOCs pollution. experiments the previous studies were carried out at concentration tens or hundreds ppm, which could not reflect actual adsorption performance activated conditions. In this study, a method w...

Any mode of transportation that is green and has a low environmental effect considered sustainable transportation. It’s all about juggling our immediate longterm interests when it comes to Rolling, riding, transit, carpooling, car sharing, electric cars are also examples urban mobility. Transportation the single greatest cause air pollution greenhouse gas emissions. Everyone can further reduce ...
