Hydrocarbon fuels from biomass

Fuel, 1989
Abstract With a view to developing petro-crops as a source of hydrocarbon fuels, indigeneous laticiferous species belonging to the families Euphorbiaceae, Asclepiadaceae and Convolvulaceae have been evaluated for their biocrude potential. Hydrocracking of biocrudes from E. royleana, E.

Solid-oxide fuel cells with hydrocarbon fuels

Proceedings of the Combustion Institute, 2005
Abstract 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%.

HYDROCARBON-AIR FUEL CELL

1966
Abstract : Research emphasized (1) the search for non-noble catalysts, (2) the development of non-corrosive intermediate temperature electrolytes and (3) studies to improve noble metal utilization. Freeze drying can be an effective method for producing conductive high surface area metal tungsten oxides catalysts but these materials did not show any ...

Hydrocarbon Fuels from Lignocellulose

2017
The main motivation for biofuels at present is to enable transportation fuels which do not contribute to global warming. Biofuels made from non-food biomass, collectively called lignocellulose, dramatically reduce the net carbon dioxide emissions from light and heavy duty vehicles. Lignocellulose consists of agricultural residue such as corn stover and

HYDROCARBON FUEL CELL ELECTRODES

1968
Abstract : The report describes the continuing evaluation of electrodes and matrix materials in fuel cell systems utilizing acid electrolytes and operating with impure hydrogen fuel. Several experimental anodes and anode catalysts were evaluated in matrix cells using 5 N H2SO4 (70C, 1% CO) and 85% H3PO4 (150C, 10% CO) electrolytes.

Lubricity of Diesel Fuel Hydrocarbons and Surrogate Fuels

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">The aim of this study is to investigate the lubricity of hydrocarbons that constitute components of petroleum diesel fuel. A number of typical hydrocarbon compounds were selected as representative of the group types of alkanes (paraffins), cycloalkanes (naphthenes) and aromatics,

Hydrocarbon-fueled scramjet combustor investigation

Journal of Propulsion and Power, 1990
An experimental program is being conducted for developing the technology required by a hydrocarbon-fueled engine capable of operating as a scramjet in the Mach 5.6-7.0 range. A series of tests have been run to define scramjet combustor design criteria applicable to a scramjet configuration involving a pair of modular, axisymmetric combustors mounted on

Hydrocarbon Fuels Optimization

2001
Abstract : Hydrocarbon fuel performance in rockets is systematically considered using standard equilibrium, isentropic, one-dimensional computer codes with a new web-based interface. For reference engine conditions the optimized specific impulse depends only upon the mass-normalized (specific) enthalpy content and the hydrogen-to-carbon ratio In this ...

Hydrogen from hydrocarbon fuels for fuel cells

International Journal of Hydrogen Energy, 2001
Abstract 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 ...
