Molten carbonate fuel cells use carbonate salts of alkali metals as electrolyte. Due to the highly corrosive nature of the electrolyte, various countermeasures are being developed. MCFCs are expected for high-efficiency power generation systems using hydrocarbon fuels, such as natural gas and coal gas. This article describes the mechanisms of operation and cell degradation, as well as the featu...

Pyrolysis of agricultural waste to produce fuel gas involves formation of tars as noxious by-products. In this paper the qualitative analysis of tars formed during pyrolysis of rice husks is presented, based on identification by gas chromatography-mass spectrometry and interpolation of retention times on a polyaromatic hydrocarbon index scale. The influence of some reaction parameters on produc...

Fusarium fujikuroi isolate FUS01 is highly adapted to grow in jet fuel with predicted genes involved in hydrocarbon catabolism and carbon assimilation. The draft genome size is estimated at 49 Mb containing 18,578 proteins with high similarity to that of F. fujikuroi isolate B14.

The scope of the CORE concept is the development of an action-ready economically viable technical solution to mitigate the environmental, and societal effects of green house gas emissions (GHG) resulting from internal combustion (IC) engines. The developed and proposed technology has been deemed Combustion of Optimized Reactivity in Engines, or CORE for short. In the United States, the transpor...

Most of the fuels used in internal combustion engines are liquid fuels. The magnetic behavior fuel leads to a change interaction hydrocarbon and oxygen molecules. This study aimed evaluate consumption engine vibration (time domain) Perkins A63544 diesel using magnetized fuel. an can cause failure components discomfort injury users. Engine changes due types combustion. Therefore, this study, tra...

Antarctic exploration and research have led to some significant although localized impacts on the environment. Human impacts occur around current or past scientific research stations, typically located on ice-free areas that are predominantly soils. Fuel spills, the most common occurrence, have the potential to cause the greatest environmental impact in the Antarctic through accumulation of ali...

The dehydrogenation of a Jet A hydrocarbon mixture was investigated for the production of hydrogen for fuel cell applications. This process differs from steam/partial oxidation reforming of hydrocarbons in that the hydrogen produced is free of CO, and therefore can be used in low temperature fuel cells without further purification. Because of their relative importance with respect to the spectr...

Polycyclic aromatic hydrocarbons (PAH) are components of complex organic mixtures featuring liquid and solid fossil fuels as well as tars derived from combustion and/or pyrolysis of coal and hydrocarbon fuels. PAH can also be detected at the exhaust of combustion systems, often associated to carbon particulate matter emissions. Due to their high toxicological potential the concentration levels ...

Recent worldwide interest in building a decentralized, hydrogen-based energy economy has refocused attention on the solid oxide fuel cell (SOFC) as a potential source of efficient, environmentally friendly, fuel-versatile electric power. Due to its high operating temperature, the SOFC offers several potential advantages over polymer-based fuel cells, including reversible electrode reactions, lo...

A numerical investigation of the structure of hydrogen/air partially premixed 'ames (PPFs) in a counter'ow con4guration is reported. The partially premixed 'ame structure is characterized by two spatially distinct reaction zones. Unlike hydrocarbon/air PPFs, the fuel is partially consumed in the rich premixed zone, where H, O, and OH are the major intermediate species, with the remaining fuel b...
