Extraction of ethane from natural gas by adsorption on modified ETS-10

A supported Cu(I)@MIL-100(Fe) adsorbent with high CO adsorption capacity and CO/N2 selectivity

“…The correlation coefficients (R 2 ) were up to 0.9995, indicating that the adsorption behaviors of CO and N 2 on the samples can be well described by the DSLF model. (Figure 7) ( Table 3) Ideal adsorbed solution theory (IAST) is widely applied to predict the adsorption selectivities of binary gas mixtures from pure component isotherms [47][48][49]. IAST assumes the adsorbed mixture is an ideal solution at constant spreading pressure and temperature, where the chemical potential of the adsorbed solution is considered to be equal to that of the gas phase at equilibrium [50].…”

Tuning the C2/C1 Hydrocarbon Separation Performance in a BioMOF by Surface Functionalization

“…Methane, as the main component (75–90 %) of natural gas, not only is a cleaner energy source for our daily life, but also a useful feedstock for various other chemicals in the petrochemical industries . In addition, ethane is the second highest fraction (1–6 %) of hydrocarbons in natural gas and an important feedstock for ethylene synthesis by steam cracking in industry . Therefore, the separation and purification of ethane from methane seem to be necessary and profitable, for it could make more efficient use and improve the economics of natural gas.…”

Equilibrium isotherms and adsorption heats analysis for ternary mixture of methane, ethane, and propane on 4A zeolite

“…The maximum adsorption capacities of three gases have been compared with their values on various adsorbents [20][21][22][23][24][25][26][27][28], a summarized in Table 4. The results in this study are in agreement with those reported in Table 4, where ethane is more selectively adsorbed on both silicalite-1 and modified Engelhard titanosilicalite-10 (Na-ETS-10) than methane.…”

“…Many studies have been done on prediction of equilibrium adsorption isotherms for light hydrocarbons on various adsorbents such as binary mixture of methane and ethane on Na-ETS-10 [7], binary and ternary mixtures of methane, ethane, and ethylene on titanosilicate ETS-10 zeolites [8], binary mixtures of methane-ethane and methane-propane on carbon nanotubes and activated carbon [9,10], binary and ternary mixtures of methane, ethane and propane on silicalite [11], ternary and quaternary mixtures of short linear alkanes involving methane, ethane, propane, and n-butane on pillared layered materials [12], binary mixtures of propane and propylene on 4A zeolite [13], binary mixture of methane and ethane on Engelhard titanosilicate-10 [14], and binary mixtures of ethane-ethylene and propane-propylene on HMS type mesoporous silica [15]. The aim of this investigation is to study experimentally and theoretically the equilibrium adsorption isotherm for ternary mixtures of methane, ethane, and propane on 4A zeolite by using the volumetric method to determine the adsorbed amount.…”
