Petroleum hydrocarbons and fuel oxygenates are among the most commonly occurring and widely distributed contaminants in the environment.

This chapter presents a. The presence of co-contaminants (other ether oxygenates, hydrocarbons and organic compounds) in soil and groundwater may limit aerobic biodegradation of ETBE by preferential metabolism and.

A recent review of fuel oxygenates and water quality (Interagency Oxygenated Fuels Assessment Steering Committee, ) notes that for various reasons, including the potentially greater persistence of MTBE in ground water than other components of gasoline, remediation of MTBE-contaminated ground water may pose unique problems.

biodegradation of petroleum hydrocarbons. However, it is possible to enhance the rate of natural biodegradation by supplying additional electron acceptors to the subsurface microbial community.

The costs of biofuel depends besides the availability, but also on efficiency, health and safety issues, legislation, fuel upgrading needs and integration issues.

Optimisation between fuel cleaning demands for SOFC and development of SOFC to tolerate dirtier fuel is one alternative.
