Deposit Formation in Hydrocarbon Fuels
Journal of Engineering for Power, 1982A high-pressure fuel coking test apparatus was designed and developed and was used to evaluate thermal decomposition (coking) limits and carbon deposition rates in heated copper tubes for two hydrocarbon fuels, RP-1 and commercial-grade propane. Tests were also conducted using JP-7 and chemically-pure propane as being representative of more refined ...

Hydrogen as aviation fuel: A comparison with hydrocarbon fuels
International Journal of Hydrogen Energy, 1997Abstract Depletion of fossil fuels and environmental considerations have led engineers and scientists to anticipate the need to develop a clean, renewable and sustainable energy system. In general, they agree that in such a system hydrogen will be used as an energy carrier.

1962 International Electron Devices Meeting, 1962
A brief review is given of fuel cell principles and types. Performance of a molten-electrolyte fuel cell at 600° C on hydrocarbon-derived fuels is then discussed. Air is used at the other electrode. Propane reformate fuel produces about 80% of the power obtained with hydrogen. A one to one mole mixture of water and methyl alcohol is also a satisfactory

Solid-oxide fuel cells with hydrocarbon fuels
Proceedings of the Combustion Institute, 2005Abstract Solid-oxide fuel cells can directly use hydrocarbon or hydrocarbon-derived fuels. Conversion efficiencies can be considerably greater than those of heat engines, with hybrid cycles in combination with heat engines and co-generation promising conversion efficiencies as high as 70%.

Hydrogen from hydrocarbon fuels for fuel cells
International Journal of Hydrogen Energy, 2001Abstract Hydrogen for use in fuel cells is typically generated in a fuel processor from available fuels (CnHmOp) by means of the reforming reaction. In this article, we describe the reforming process, discuss the three principal pathways (steam reforming, partial oxidation, and autothermal reforming), and demonstrate that the process is most ...

Combustion Promoters for Hydrocarbon Fuels
Chemistry and Technology of Fuels and Oils, 2016We present a review of combustion promoters, including the major classes of organic compounds that can be used in internal combustion engines. We also consider compounds developed that have high promoter action. We give a comparative evaluation of the considered promoters based on analysis of the mechanism of action for the promoters.

Fuel and Hydrocarbon Vaporization [PDF]
, 1973 Abstract : A new semi-empirical expression has been developed which predicts the evaporation rates of pure liquid hydrocarbons under a wide range of conditions. A code has been formulated which, using the above results, calculates the evaporation rates of binary mixtures of hydrocarbons.

Combustion temperatures of hydrocarbons and fuels
Chemistry and Technology of Fuels and Oils, 19721. In the combustion of aromatic hydrocarbons, the engine combustion-chamber temperature is substantially higher than that with isoparaffins. Of the aromatics that were studied, benzene gives the highest combustion temperature and m-xylene the lowest. 2.
