Currently, there are over 62,000 petroleum-contaminated sites undergoing remediation in the United States. Understanding attenuation rates for dissolved contaminant concentrations and factors that influence these is important to effectively manage move them towards closure. The GeoTracker California Department of Public Health databases provide more than 15 years groundwater monitoring results ...

In this work, the interactions of methyl tert-butyl ether (MTBE) on different dealuminated high silica zeolites were studied by means of both experimental and computational approaches. Zeolites with different textural and surface features were selected as adsorbents and the effect of their physico-chemical properties (i.e. pore size architecture and type and amount of surface OH sites) on sorpt...

Concerns for atmospheric pollution from auto exhaust have led to the blending of "oxygenates" with motor fuels. The most common oxygenate, methyl tert-butyl ether (MTBE) is currently required within several metropolitan areas (Denver and Phoenix) in the range of 12% of the motor fuel. Amendments to the Clean Air Act may expand this requirement to as many as 44 other areas of the United States i...

A widely used gasoline additive, methyl tertiary butyl ether (MTBE), has been controversial, in part because of concerns about potential inhalation health effects and more recently because of added concerns about water contamination. Although many of the issues related to MTBE have not been fully resolved, several apparent paradoxes can be discerned, including the fact that something intended t...

The idea of model transformation by example (MTBE) is to use an example of the transformation to derive transformation rules. Although some works propose automatic and semi-automatic approaches, there are some limitations to use them in practice. As a result, depending on the model transformation it may be necessary to apply an MTBE approach manually. Therefore, this work presents a manual MTBE...
