Due to the shortage of liquid hydrocarbon fuels for compression ignition engines, researchers have constantly been looking for alternative fuels. Recently, dim ethyl ether (DME) with its interesting properties, such as high cetane number and low exhaust emission has drawn a lot of interst as a suitable fuel for diesel engines. The main objective of this study was to assess the potentials and fe...

The use of correlation-gas chromatography to measure the vaporization enthalpy {∆l Hm(298.15 K)} of complex fuels is demonstrated using RP-1, JP-7, and JP-8, which are all rocket and jet fuels. Vaporization enthalpies of 308, 341, and 441 kJ/kg have been obtained assuming average compositions of C12H23.4, C12H25, and C11H21, respectively. The H/C ratio in these fuels has been measured by 1H NMR...

An approach has been proposed combining one dimensional inverse gated C NMR spectroscopy and a comprehensive two dimensional gas chromatography (GC×GC) to analyze diesel fuels prior and after oxidation under the standard conditions. Classes of hydrocarbons present before and after oxidation have been identified and quantified. A decrease in aromatic isoand n-paraffinic hydrocarbons and an incre...

To address the issues of greenhouse gas emissions associated with fossil fuels, vegetable oilseeds, especially non-food oilseeds, are used as an alternative fuel resource. Vegetable oil derived from these oilseeds can be upgraded into hydrocarbon biofuel. Catalytic cracking and hydroprocessing are two of the most promising pathways for converting vegetable oil to hydrocarbon biofuel. Heterogene...

Modern energy challenges have motivated the development of electrochemical transformations of abundant feedstocks into valuable fuels and commodity chemicals. Now, reporting in ACS Central Science, Surendranath and co-workers introduce an electrochemical strategy that enables an organic transformation long-considered a grand challenge: selective methane activation. Methane, the primary componen...

A two-dimensional numerical model of a single-chamber solid oxide fuel cell SCFC operating on hydrocarbon fuels is developed. The SCFC concept is a simplification of a conventional solid oxide fuel cell in which the anode and cathode are both exposed to the same premixed fuel-air mixture, and selective catalysts promote electrochemical oxidation of the fuel at the anode and simultaneous electro...

The major microbial problem in the petroleum refining industry is contamination of stored products, which can lead to loss of product quality, formation of sludge and deterioration of pipework and storage tanks, both in the refinery and at the end-user. Three major classes of fuel are discussed in this article gasoline, aviation kerosene and diesel, corresponding to increasingly heavy petroleum...

The impact on the usage of commercial fuels such as gasoline in automobile vehicles is an alarm in terms of health effects as it emits higher level of carbon dioxide to the atmosphere. In addition, the need and demand for Gasoline products are in the increasing trend because of more number of vehicles which are on road and Governments plan to increase the cost of fuel. As slowly the scarcity of...
