These apertures are of a similar size to ethylene molecules, but owing to the size, shape and rigidity of the pores, act as molecular sieves to prevent the transport of ethane. The efficiency of this molecular sieve for the separation of ethylene/ethane mixtures is validated by breakthrough ...
Replacement or debottlenecking of the extremely energy-intensive cryogenic distillation technology for the separation of ethylene from ethane has been a long-standing challenge. Membrane technology could be a desirable alternative with potentially lower
While the formation of occupied 512cages dominates methane hydrate nucleation, nucleation of ethane hydrates predominately exhibits the 4151062cage as both the first and most common early cage type. These 4151062cages do not occur in the crystal structure, and due to their oblong shape, restrict ...
These hydrocarbons are called alkanes (saturated hydrocarbons). 烷烃名称: 表示链中碳原子数的词干+ "-ane": 词干meth- 表示一个碳原子,甲烷methane是一种具有一个碳原子的烷烃。 词干eth-表示两个碳原子,乙烷ethane是具有两个碳原子的烷烃。 词干prop- 表示三个碳原子,丙烷propane是具有三个碳原子的烷烃。

The sorption isotherms for binary mixtures of methane, ethane, propane and tetrafluoromethane have been determined in carbon nanotubes using configurational bias Monte Carlo simulation techniques. At high loadings, a curious maximum for equimolar gas-phase mixtures occurs with increasing pressure in the ...

The 2-eV shape resonance in N2-electron scattering is calculated by a self-consistent-field energy-variational procedure. The resonance state corresponds to the attachment of an incident d-wave electron to the 1πg valence orbital of the metastable 2Πg state of N2-. The resonant behavior is...

Generally, hydrocarbon derivatives of low molecular weight, e.g., methane, ethane, and propane, are gases; those of intermediate molecular weight, e.g., hexane, heptane, and octane, are liquids; and those of high molecular weight, e.g., eicosane (C20H42) and polyethylene, are solids. ...
