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...

Breath ethane, O2 consumption, and CO2 production were analyzed in 24-mo-old female Fischer 344 rats that had been fed continuously ad libitum (AL) or restricted 30% of AL level (DR) diets since 6 wk of age. Rats were placed in a glass chamber that was first flushed with air, then with a gas mixture containing 12% O2. After equilibration, a sample of the outflow was collected in gas sampling ba...

A supercritical ethane working fluid Brayton power conversion system is evaluated as an alternative to carbon dioxide. The HSC® chemical kinetics code was used to study thermal dissociation and chemical interactions for ethane and other coolants under a variety of conditions. The NIST database was used for reaction rates. Overall results were not conclusive. The supercritical behavior of ethane...

  Abstract: In this work, the kinetics of ethane hydrate formation has been studied experimentally and a kinetic model based on chemical affinity has been described for predicting the hydrate growth process in the stirred batch reactor at a constant volume. The experiments were done with both pure water and aqueous solution of sodium dodecyl sulfate (SDS). The effect of SDS on formation kineti...

ch4, c2h6 and c2h4 are the most important outlet gaseous of oxidative couple methane (ocm) reaction and this process is a new technology for conversion of natural gas to ethane and ethylene products. in this study, adsorption of ocm outlet hydrocarbons over 10x zeolite has been examined at equilibrium conditions. temperature and pressure are the most effective operational parameters in the batc...

Generally, rotational isomerization about the carbon-carbon single bond in simple ethane derivatives in room-temperature solution under thermal equilibrium conditions has been too fast to measure. We achieved this goal using two-dimensional infrared vibrational echo spectroscopy to observe isomerization between the gauche and trans conformations of an ethane derivative, 1-fluoro-2-isocyanato-et...

We recently proposed Ethane: A clean-slate approach to managing and securing enterprise networks. The goal of Ethane is to make enterprise networks (e.g. networks in companies, universities, and home offices) much easier to manage. Ethane is built on the premise that the only way to manage and secure networks is to make sure we can identify the origin of all traffic, and hold someone (or some m...

The title compound, C(6)H(10)N(8)S(2), was prepared by the nucleophilic substitution reaction of 5-mercapto-1-methyl-tetra-zole and dichloro-ethane. In the crystal, the mol-ecule possesses an approximate non-crystallographic twofold symmetry axis. The crystal packing is stabilized by weak inter-molecular C-H⋯N and π-π inter-actions [centroid-centroid distances = 3.448 (6), 3.5085 (5) and 3.4591...

Ethane exhalation was measured in 42 control subjects, 52 patients with various non-alcoholic liver diseases, and 89 alcohol abusers who had been admitted to hospital for alcohol withdrawal and assessment of liver disease (six with normal liver tests, 10 with steatosis with or without fibrosis, six with alcoholic hepatitis, 29 with cirrhosis, 34 with both cirrhosis and alcoholic hepatitis, and ...
