Hopes for a flame-free future
Article Abstract:
It has been possible to develop a fuel cell that emulates nature's ability to use biochemical routes to use the hydrogen stored naturally in hydrocarbons to produce clean power. The researchers used a copper catalyst intimately in contact with cerium oxide to produce a porous anode material. There was strong evidence of total chemical conversion and electron transfer through a zirconia electrolyte membrane when this material operated on pure butane for 48 hours. It may be possible to use partly oxidized fuels such as formic acid for catalytic conversion to energy and heat, as these fuels will function in aqueous solutions with catalytic electrodes.

Low-temperature thermal generation of hydrocarbon gases in shallow shales
Article Abstract:
An analysis of isotope ratios of methane, ethane, propane and butane components of gases collected during the drilling of 20 oil wells in the Western Canadian sedimentary basin indicates that low-temperature thermal generation of non-methane hydrocarbons takes place at temperatures lower than 62 degrees C and possibly as low as 20 degrees C. The use of isotopic fingerprints to analyze gas-source depths in the Western Canadian sedimentary basis has significantly cut well-remediation costs. This approach could also replace almost all other logging techniques traditionally used to identify the source of leaking gas.

Determining the temperature of petroleum formation from the kinetic properties of petroleum asphaltenes
Article Abstract:
Research is presented concerning the evaluation of the thermal history of hydro-carbon forming basins to predict the reserves of petroleum which may be found in the source rocks. The structural similarity of parent kerogen and asphaltenes is discussed.
