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 ...

Combustion of hydrocarbon fuels and liquid alternative fuels

2020
Experimental investigations are carried out to elucidate the influences of the amount of fuel and oxygen on critical conditions of autoignition and extinction with the gaseous counterflow burner for propane and the liquid pool counterflow burner for n-heptane, isobutanol, n-heptane/isobutanol-mix, 1-propanol, ethanol, n-decane, ndecane/isobutanol-mix ...

Combustion Promoters for Hydrocarbon Fuels

Chemistry and Technology of Fuels and Oils, 2016
We 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.

Deposit Formation in Hydrocarbon Fuels

Journal of Engineering for Power, 1982
A 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 ...

Deflagration of Hydrocarbon Aerosol Fuels

Combustion Science and Technology, 1997
Aerosols of hydrocarbon/air may be formed on accidental release of product in the chemical and process industries and pose a fire and explosion hazard. Some very large-scale accidents involving such systems have been reported. This paper reports a series of novel scouting experiments in a purpose-built medium-scale facility, designed to throw light on ...
