Soil adsorption behaviour and photomineralization by photocatalytic membranes immobilizing titanium dioxide of atrazine and intermediates
General
The soil adsorption behaviour of atrazine and its photodegradation intermediate 4,6-diamino-2-chloro-1,3,5- s-triazine (I), was evaluated by measuring partition coefficients on five representative European topsoils using classical batch experiments. From this study, (I) appears to be less...
Production of low aromatics and low sulfur diesel in a hydrodesulfurization (HDS) pilot plant unit
General
The present work investigates the hydrotreating process of a diesel in order to achieve lower sulphur and aromatics content. The entire work was performed in a Hydrodesulphurization (HDS) pilot plant unit located in Chemical Process Engineering Research Institute (CPERI). For the tests, a commercial...
Organic atmospheric pollutants: polycyclic hydrocarbons from coal atmospheric fluidised bed combustion (AFBC)
General
The work deals with coal combustion in a pilot-plant fluidised bed (7 cm i.d.) under atmospheric conditions. The aims are to capture and analyse qualitatively as well as quantitatively the volatile polycyclic hydrocarbons emitted by using coal as energy source under various combustion conditions...
Modeling atmospheric aerosol using thermodynamic arguments - A Review
Air pollution and health
Atmospheric aerosols have been implicated in human health effects, visibility reduction in urban and regional areas, acidic deposition, and altering the earth’s radiation balance. A major goal of scientific research for the last fifteen years has been the development of the necessary models, using...
Electricity generation and atmospheric pollution: The role of solid fuels gasification
General
Electricity generation in solid fuel fired power stations is currently the main source of flying particulates and greenhouse gases emissions. Environmental pollution is expected to deteriorate dramatically in the coming century unless pollution abatement technologies for solid fuels energy...
Tropospheric ozone in the Czech Republic, 1994-2000
