C2H2, C2H4, and C2H6 are important oil-dissolved gases in power transformers. Detection of the composition and content of oil-dissolved gases in transformers is very significant in the diagnosis and assessment of the state of transformer operations. The commonly used oil-gas analysis methods have many disadvantages, so this paper proposes a Ni-doped carbon nanotube (Ni-CNT) gas sensor to effect...

Kinetic and isotopic studies showed that C-H bond activation in ethane by surfaces essentially saturated with lattice oxygens is the sole kinetically relevant step in ethane oxidation on Mo-V-NbOx mixed oxides. These conclusions are consistent with the dependence of oxidation rates on O2 and C2H6 pressures, with H/D exchange and kinetic isotope effects, and with the preferential initial incorpo...

Selfand binary Maxwell-Stefan diffusion coefficients were determined by equilibrium molecular dynamics simulations with the Green-Kubo method. This study covers selfdiffusion coefficients at liquid states for eight pure fluids, i.e. F2, N2, CO2, CS2, C2H6, C2H4, C2H2 and SF6 as well as Maxwell-Stefan diffusion coefficients for three binary mixtures N2+CO2, N2+C2H6 and CO2+C2H6. The fluids were ...

Influence of the presence of CO2, which is a mild oxidant, on the performance of the thermal cracking of ethane to ethylene in the absence or presence of limited O2 at different temperatures (750– 900°C), space velocities (1500–9000 h) and CO2/C2H6 and O2/C2H6 mole ratios (0–2⋅0 and 0–0⋅3 respectively) has been investigated. In both the presence and absence of limited O2, ethane conversion incr...

A possibility of photocatalytic production of useful aliphatic hydrocarbons and H2 from various organic compounds, including acetic acid, methanol, ethanol and glucose, over Fe-modified TiO2 is discussed. In particular, the influence of the reaction atmosphere (N2, air) was investigated. Different gases were identified in the headspace volume of the reactor depending on the substrate. In genera...

Abstract. Gas flaring is a substantial global source of carbon emissions to atmosphere and targeted as route mitigating the oil gas sector footprint due waste resources involved. However, quantifying from resource-intensive, no studies have yet assessed for offshore regions. In this work, we present dioxide (CO2), methane (CH4), ethane (C2H6), NOx (nitrogen oxide) data 58 emission plumes identi...

The development of a continuous wave, thermoelectrically cooled (TEC), distributed feedback diode laser-based spectroscopic trace-gas sensor for ultra-sensitive and selective ethane (C2H6) concentration measurements is reported. The sensor platform used tunable diode laser absorption spectroscopy (TDLAS) and wavelength modulation spectroscopy as the detection technique. TDLAS was performed usin...
