Transition metal oxide catalysts as an alternative for the oxidation of nitrogen monoxide to nitrogen dioxide: kinetic modelling at high space velocity

18.10.2014 | Leonardo Tecchio, Pablo Marín, Fernando V. Díez, Salvador Ordóñez, Journal of Chemical Technology & Biotechnology, 2014

Abstract Background The oxidation of NO to NO2 is a key step in environmental pollution abatement techniques, such as the “fast‐SCR” or the diesel engines catalytic traps. In both cases, the conversion of an important fraction of NO into NO2 is a key step. In this work, two commercially ...

Numerical Study of the Formation of Soot Precursors during Low-Temperature Combustion of a n-Butanol–Diesel Blend

17.10.2014 | Xiaorong Zhou; Mengtian Song; Haozhong Huang; Ruzhi Yang; Mingxia Wang; Jiaxing Sheng, Energy & Fuels, 2014

To study the soot precursor emission characteristics of a n-butanol–diesel blend during low-temperature combustion (LTC), a model of n-heptane, n-butanol, polycyclic aromatic hydrocarbons (PAHs), and toluene was chosen. Computational fluid dynamics (CFD) software was used to establish a ...

Deep-Sea Field Test of the CH4 Hydrate to CO2 Hydrate Spontaneous Conversion Hypothesis

17.10.2014 | Peter G. Brewer; Edward T. Peltzer; Peter M. Walz; Elizabeth K. Coward; Laura A. Stern; Stephen H. Kirby; John Pinkston, Energy & Fuels, 2014

We have carried out a small-scale deep-sea field test of the hypothesis that CH4 gas can be spontaneously produced from CH4 hydrate by injection of a CO2/N2 gas mixture, thereby inducing release of the encaged molecules with sequestration of the injected gas. Pressure cell studies have shown ...
