The use of gasoline oxygenated with MTBE (methyl tert-butyl ether) reduced significantly air pollution (16 - 23% lower emissions of CO and 18% lower emissions of unburned hydrocarbons) but increased water pollution. There is no European or national regulations for MTBE in drinking water except for Denmark, which has set a limit value of 30 Âľg/ L for MTBE. USEPA proposed a maximum concentration of 20- 40 Âľg/L. This paper is a review with 70 references on the MTBE production, use, properties and...

Common issues of the gasification systems relate to filtering apparatus. Dry filtering processes are simple and reliable. However, the filtering material defines the maximum and minimum temperature at which the filter can operate properly. In addition, dry filtration is not effective on light tar compounds (i.e. benzene and toluene) or ammonia compounds. On the other hand, despite being very efficient, wet filters drop the gas temperature below the line of condensation of tar, ammonia and ste...

Eutrophication is water pollution initiated by high amounts of plant nutrients. With the excess influx of nutrients from human activities, the eutrophication process begins and causes a breeding ground for algae. The amount of nutrients present in any given cycle will be higher than the levels present in previous cycles. Therefore, it is very important to manage water quality in lakes and dams to prevent and to slow or to reverse the eutrophication process. This can be ensured by using effect...

This paper reports an improved chlorolignin (CL) oxidative decolorization in alkaline media by the use of a heterogeneous system consisting of hydrogen peroxide and a silica [bis(dibenzoylmethido) copper II] (S1) catalyst. The catalytic functions of S1 in the presence of H2O2 were evaluated by comparing the chlorolignin decolorization in media with and without addition of catalyst. Since decolorization is associated with CL degradation, the pH variation and chloride release assays were carrie...
