Decarbonized hydrogen and electricity from natural gas
International Journal of Hydrogen Energy, 2005This paper discusses configuration, attainable performances and thermodynamic features of stand-alone plants for the co-production of de-carbonized hydrogen and electricity from natural gas (NG) based on commercially available technology. We focus on the two basic technologies currently used in large industrial applications: fired tubular reformer ...

On the Nature of Blueshifting Hydrogen Bonds
Chemistry – A European Journal, 2014AbstractThe block‐localized wave function (BLW) method can derive the energetic, geometrical, and spectral changes with the deactivation of electron delocalization, and thus provide a unique way to elucidate the origin of improper, blueshifting hydrogen bonds versus proper, redshifting hydrogen bonds.

The Journal of Chemical Physics, 1959
Starting from a molecular orbital viewpoint, a general description is given of hydrogen bonds X—H···Y. The case of weak hydrogen bonds, as in associated liquids, is developed in detail, with the O–H···O bond as an example. The new feature in the treatment is the introduction of excited 2s and 2p orbitals of the hydrogen atom (Sec. II), the consequences

International Journal of Hydrogen Energy, 1983
In the future, hydrogen will be required to supplement and eventually replace a rapidly diminishing natural gas resource for stationary type combustion engines. Combustion properties, knock rating, engine performance and emissions of methane (the chief constituent of natural gas) and hydrogen are different as engine fuels.

The Relative Abundance of Hydrogen Isotopes in Natural Hydrogen
Physical Review, 1932The relative abundances of isotopes have been investigated extensively in recent years, but few researches of such ratios when one isotope is very rare have been reported. We have investigated a number of samples of hydrogen from various sources, water from the crater of Mc. Kilauea, an obsidian, Devonian water, and hydrogen from helium bearing natural

Natural Hydrogen in Western Australia
PESA GazetteThe nascent field of natural hydrogen investigations is expanding rapidly worldwide. Recent studies in Australia have documented hydrogen in natural gas samples in both sedimentary basins and cratonic settings, and discussed multiple abiogenic sources for natural Hydrogen (Boreham et al., 2021a,b).

Nature of the Hydrogen Bond in Potassium Hydrogen Fluoride
Nature, 1947In 1941 Ketelaar1 published accurate measurements on the infra-red absorption and reflexion spectra of potassium hydrogen fluoride (KHF2). The two strong peaks of 1450 and 1222 cm.−1 were interpreted as a doubling of the fundamental asymmetric valence frequency v3 belonging to the vibration of a proton between two F− ions.
