Although a number of low temperature processes have been studied, only a few have been used commercially. These have been limited in the types of coal that are acceptable, and the by-products are less valuable than those obtained from high temperature processing. The Disco process is used in the United States to supply a limited amount of fuel to meet requirements of smoke ordinances. The British CoaUte and Rexco processes produced substantial amounts of domestic smokeless fuel. Development of fluid-bed methods of carbonizing finer coal at ca 400°C has been studied in the United Kingdom. A reactive char is briquetted without a binder to produce a premium open-fire smokeless fuel. 

The subjeet of fluidization and researeh and development in this field, probably reaehed its peak in the early 1980 s with extensive work being applied by the petroleum industry in synthetie fuels development sueh as shale oil, eoal gasifieation, pyrolysis applications. Prior to this, significant development work was done in the petroleum industry for flexieraeking and flexieoking operations. Fluidization still remains an area of aetive researeh and industry development, and the teehnology is well established in a variety of industry seetors.

These are essentially P4 explosives which incorporate the fuels developed for P5 types to avoid the danger of deflagration. When fired off the solid the confinement is sufficient to ensure that the explosive develops its full power and can perform the required work. 

More complex hydrocarbonaceous fuels might materialize in the long term, depending on the alternative vehicle market. The fuel development programs also include hydro-carbonaceous fuels for both, on-board reformers and for liquid hydrocarbon fuel cells. The introduction of hybrid and FC cars would inevitably reduce the share of gasoline in total fuel consumed.

Dynagas A noncatalytic process for hydrogenating coal to produce gas or light oil fuels. Developed by Hydrocarbon Research. 

Esterfip A process for transesterifying vegetable oils to their methyl esters, for use as diesel fuels. Developed by IFP and Sofiproteol, France. 

PEATGAS A process for converting peat to gaseous fuels. Developed from 1974 to 1980 by the Institute of Gas Technology, Chicago, and the Minnesota Gas Company, to use the peat deposits in Northern Minnesota. 

SynSat [Synergetic Saturation] A process for removing aromatic hydrocarbons and sulfur compounds from diesel fuel. Developed by ABB Lummus Crest and Criterion Catalyst Company. Six units were operating in 1996. 

C02 is a major factor in the cycles that built up our mineral resources. Fossil fuels developed over several hundred million years during the Phanerozoic era. There was abundant life for about 600 million years. 

Briefly, JP-4 is a wide-cut fuel developed for broad availability in times of need. JP-6 is a higher cut than JP-4 and is characterized by fewer impurities. JP-5 is specially blended kerosene, and JP-7 is a high-flash-point special kerosene used in advanced supersonic aircraft. JP-8 is a kerosene fraction that is modeled on jet A-1 fuel (used in civilian aircraft). For this profile, JP-4 will be used as the prototype jet fuel, due to its broad availability and extensive use. 

As the solubility is exceeded in the zirconium, precipitation of zirconium hydride commences and ultimately the ductility of the alloy can be reduced leading to the possibility of cracks. Thus an additional requirement in fuel development was a thorough understanding of the hydriding mechanism, sources of hydrogen, rate controlling steps, protective methods, specifications of materials and processes, and quality assurance to achieve the required performance.

In this review, we are most interested in the implications of the changing energy landscape for the reactive pathways involved. As the nature of the fuels used in everyday life change, the reactive radical intermediates formed in their combustion will also change. We will examine the context of two classes of relevant fuel developments.

Basic to the entire exercise is the issue of how much alternative fuel development can be reasonably expected over the next twenty years. Given the previous synfuel program parameters, sulfur output then depends on both the characteristics of the original fuel source and the specific method of processing. These also serve to determine the location of the sulfur output. 

With less than 5 percent of the worlds population, the United States ranks first in carbon dioxide emissions and is responsible for about 25 percent of global carbon dioxide emissions. Industrial nations worldwide are responsible for about 58 percent of carbon dioxide emissions, primarily from the combustion of fossil fuels. Developing nations account for the remaining 42 percent, but their sources of carbon dioxide are split between fossil fuels (19 percent) and deforestation (23 percent).

Leading programmes to support fuel developments, you ll use combustion fundamentals, combustion diagnostics, flow visualization and modelling toolsets, and deliver technical data based on fuel test programmes. You ll need at least five years mechanical or combustion chemistry experience and a relevant degree, while a PhD in combustion chemistry or similar would be useful.
