JP-10 (fuel)

Last updated

JP-10 (Jet Propellant 10) is a synthetic jet fuel, specified and used mainly as fuel in missiles. Being designed for military purposes, it is not a kerosene based fuel.

Contents

Developed to be a gas turbine fuel for cruise missiles, [1] it contains mainly exo-tetrahydrodicyclopentadiene (exo-THDCPD) with some endo-isomer impurity. [2] About 100 ppm of alkylphenol-based antioxidant is added to prevent gumming. Optionally, 0.10–0.15% of fuel system icing inhibitor may be added. [3] Exo-THDCPD is produced by catalytic hydrogenation of dicyclopentadiene and then isomerization. [4]

It superseded JP-9, which is a mixture of norbornadiene-based RJ-5 fuel, tetrahydrodicyclopentadiene and methylcyclohexane, because of a lower temperature service limit and about four times lower price. [5] Since the lack of volatile methylcyclohexane makes its ignition difficult, a separate priming fluid PF-1 with about 10-12% of this additive is required for the engine start-up. [5] Its main use is in the Tomahawk missiles. [6]

The Russian equivalent is called detsilin  [ ru ].

Chemical properties of JP-10 fuel

Uses

JP-10 absorbs heat energy, so is endothermic with a relatively high density of 940 kg/m3. It has a low freezing point of less than −110 °C (−166 °F) and the flash point is 130 °F (54 °C). The high energy density of 39.6 MJ/L makes it ideal for military aerospace applications - its primary use. The ignition and burn chemistry has been extensively studied. [8] [9] [10] The exo isomer also has a low freezing point. [11] [12] Its other properties have also been studied extensively. [13] [14] [15] [16] [17]

Even though its uses are mainly for the military, the relatively high cost has meant research has been undertaken to find lower costs routes including the use of cellulosic materials. [18]

<span class="mw-page-title-main">Biofuel</span> Type of biological fuel

Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste. Biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuels are regarded as a renewable energy source. The use of biofuel has been subject to criticism regarding the "food vs fuel" debate, varied assessments of their sustainability, and ongoing deforestation and biodiversity loss as a result of biofuel production.

As an intermediate in organic synthesis, it is used widely in the manufacture of pesticides, explosives, fibers, and coatings.

Dicyclopentadiene is a co-produced in large quantities in the steam cracking of naphtha and gas oils to ethylene. The major use is in resins, particularly, unsaturated polyester resins. It is also used in inks, adhesives, and paints.

As the world's energy demand continues to grow, the development of more efficient and sustainable technologies for generating and storing energy is becoming increasingly important. According to Dr. Wade Adams from Rice University, energy will be the most pressing problem facing humanity in the next 50 years and nanotechnology has potential to solve this issue. Nanotechnology, a relatively new field of science and engineering, has shown promise to have a significant impact on the energy industry. Nanotechnology is defined as any technology that contains particles with one dimension under 100 nanometers in length. For scale, a single virus particle is about 100 nanometers wide.

Flame lift-off in oil fired pressure jet burners is an unwanted condition in which the flame and burner become separated. This condition is most commonly created by excessive combustion air and often results in the loss of flame as the photoelectric cell fails to register the light of the flame, this in turn results in a safety lockout of the control box.

A cool flame is a flame having a typical temperature of about 400 °C (752 °F). In contrast to an ordinary hot flame, the reaction is not vigorous and releases little heat, light, or carbon dioxide. Cool flames are difficult to observe and are uncommon in everyday life, but they are responsible for engine knock – the undesirable, erratic, and noisy combustion of low-octane fuels in internal combustion engines.

Micro-combustion is the sequence of exothermic chemical reaction between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species at micro level. The release of heat can result in the production of light in the form of either glowing or a flame. Fuels of interest often include organic compounds in the gas, liquid or solid phase. The major problem of micro-combustion is the high surface to volume ratio. As the surface to volume ratio increases heat loss to walls of combustor increases which leads to flame quenching.

Chemical looping reforming (CLR) and gasification (CLG) are the operations that involve the use of gaseous carbonaceous feedstock and solid carbonaceous feedstock, respectively, in their conversion to syngas in the chemical looping scheme. The typical gaseous carbonaceous feedstocks used are natural gas and reducing tail gas, while the typical solid carbonaceous feedstocks used are coal and biomass. The feedstocks are partially oxidized to generate syngas using metal oxide oxygen carriers as the oxidant. The reduced metal oxide is then oxidized in the regeneration step using air. The syngas is an important intermediate for generation of such diverse products as electricity, chemicals, hydrogen, and liquid fuels.

<span class="mw-page-title-main">Tricyclodecane</span> Chemical compound

Tricyclodecane (TCD) is an organic compound with the formula C10H16. It is classed as a hydrocarbon. It has two main stereoisomers–the endo and exo forms. Its primary use in the exo form is as a component of jet fuel. It is used here primarily because of its high energy density. The exo isomer also has a low freezing point. Because of this, its properties have been studied extensively. It is often called tetrahydrodicyclopentadiene.
