The conversion of syngas (CO + H2) to gasoline-ranged hydrocarbons was carried out using a hybrid catalyst consisting of metal-loaded ZSM-5 coupled with Cu-ZnO in a near-critical n-hexane solvent. Methanol was synthesized from syngas over Cu-ZnO; subsequently, was converted to hydrocarbons through the formation of dimethyl ether (DME) over the metal-loaded ZSM-5. When 0.5 wt% Pd/ZSM-5 and 5 wt%...

A carbon tax would penalize carbon intensive fuels like gasoline and shift fuel consumption to less carbon intensive alternatives like biofuels. Since biofuel production competes for land with agriculture, a carbon tax could raise land rents, divert land towards fuel production, and raise agricultural prices. This paper analyzes the welfare effect of a carbon tax on fuel with gasoline and biofu...

Work undertaken by Lotus Engineering and partners has shown that the miscibility of the low-carbon-number alcohols with gasoline provides a powerful tool to enable the introduction of methanol as a transport fuel in a wholly evolutionary manner. This is primarily facilitated by the fact that the CAFÉ regulations in the US (together with other incentives in other countries, such as Sweden) have ...

Stringent regulations worldwide will limit the level ofparticulate matter (PM) emitted from gasoline engines equipped with direct fuel injection. Gasoline particulate filters (GPFs) present one strategy for meeting PM limits over the full operating range of the engine. Over time these filters accumulate incombustible ash, increasing system pressure drop and adversely effecting engine performanc...

This paper evaluates how gasoline prices influences the average fuel economy of the existing automobile fleet. Higher fuel price affects fleet composition in two ways: immediate purchase decisions of new, more fuel efficient, vehicles and scrappage of old fuel inefficient gas-guzzlers. Gasoline costs account for 65% of the total operating costs of driving an automobile. Rational forward-looking...

A Concise Background on Fuel Oxygenates Fuel oxygenates are oxygencontaining compounds (e.g., ethers and alcohols) that are added to gasoline either to boost the octane rating, to make the fuel burn cleaner by increasing the oxygen content, or to achieve a combination of both. The most commonly used oxygenates are methyl tertiary-butyl ether (MTBE) and ethanol. Other oxygenates include tertiary...

In response to the widespread contamination caused by MTBE-blended reformulated gasoline (RFG), legislative initiatives in several states and at the federal level have phased out, or are trying to phase out, the use of MTBE as a gasoline oxygenate. Ethanol is currently the most likely gasoline oxygenate alternative to MTBE. This potential for increased use of ethanol has been most widely acknow...

OBJECTIVE To examine the risks associated with home storage of gasoline and to outline prevention strategies to avoid further injury and death. DESIGN Case series. PATIENTS AND OTHER PARTICIPANTS Twenty-five patients less than 6 years old were selected for study (3 by presentation to a tertiary care Children's Hospital Emergency Department, and 22 from the National Electronic Injury Surveil...

This research looks at the use of high frequency (HF) magnetic fields to desorb/reduce harmful chemical compounds within gasoline and diesel that commonly leak out of underground storage tanks. Using a multi-strand coil design, measured magnetic fields of over 3 kilo-amperes per meter are generated at an optimal frequency of 117 kHz without skin-depth losses, and without the use of expensive su...
