Development of zeolite based acid catalysts for the synthesis of methyl tertiary butyl ether
Methyl tertiary butyl ether (MTBE) an antiknock additive presently used in gasoline blends as a safer alternative to lead compounds, is currently synthesized industrially from methanol and isobutene over an acidic ion-exchange resin Amberlyst-15. This commercial catalyst, although very active, …

Assessing the Spatial and Temporal Distribution of MTBE and BTEX Compounds in Lake Lewisville, Texas February 1999 - February 2000
The spatial and temporal distribution of Methyl Tertiary-Butyl Ether (MTBE) and BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) compounds were assessed in a multipurpose reservoir, Lake Lewisville, Texas between February 1999 and February 2000. Concentrations of MTBE ranged from 0.0 - 16.7 mg/L. …

Sequential Electron Acceptor Model of Intrinsic Bioremediation at a BTEX Contaminated LUST Site in Laurel Bay, South Carolina
… ethylbenzene, and xylene (BTEX) as well as methyl tertiary butyl ether (MTBE) leaked into the subsurface at the site late in 1990, and monitoring of the water table elevations and contaminant concentrations began in 1993. Using the field data, the groundwater flow model MODFLOW was used to …

Removal of selected water disinfection byproducts, and MTBE in batch and continuous flow systems using alternative sorbents.
… (TCE), bromodichloromethane (BDCM), methyl tertiary butyl ether (MTBE), bromate and bromide ions. Sorbents used included light weight aggregate (LWA), an inorganic porous material with unique surface characteristics, Amberlite® XAD-16, a weakly basic anion exchange resin, Amberjet®, a …

Biodegradation of Fuel Oxygenates in Northeastern United States Aquifers with an Analysis of Underground Storage Tank Leaks
… formulations during the past 20 years has been methyl tertiary butyl ether (MTBE), which has traditionally been viewed in both the scientific and the regulatory communities as relatively recalcitrant to biodegradation. However, cases of both in and ex situ MTBE biodegradation have recently been …

Degradation of gasoline oxygenates in the subsurface
Tertiary butyl alcohol (TBA), methyl tertiary butyl ether (MTBE) and ethyl tertiary butyl ether (ETBE) are compounds with the potential for use as oxygenates in reformulated gasolines. Being relatively soluble in water, these organics, if accidentally discharged into the subsurface, may rapidly …
