Synergetic effect of carbon nanopore size and surface oxidation on CO2 capture from CO2/CH4 mixtures [PDF]
, 2013 We have studied the synergetic effect of confinement (carbon nanopore size) and surface chemistry (the number of carbonyl groups) on CO2 capture from its mixtures with CH4 at typical operating conditions for industrial adsorptive separation (298 K and ...

A NOVEL CO2 SEPARATION SYSTEM [PDF]
, 1999 Because of concern over global climate change, new systems are needed that produce electricity from fossil fuels and emit less CO{sub 2}. The fundamental problem with current CO{sub 2} separation systems is the need to separate dilute CO{sub 2} and pressurize it for storage or sequestration.

Folding of graphene slit like pore walls—a simple method of improving CO2 separation from mixtures with CH4 or N2 [PDF]
, 2014 We report for the first time a detailed procedure for creating a simulation model of energetically stable, folded graphene-like pores and simulation results of CO2/CH4 and CO2/N2 separation using these structures.

Research progress of CO2 separation technology by solvent absorption [PDF]
E3S Web of Conferences, 2023 The combustion of fossil fuels emits a large amount of CO2, which causes the greenhouse effect and leads to global warming and poses a serious threat to life on earth.

CO2 SEPARATIONS USING ZEOLITE MEMBRANES [PDF]
, 2001 Zeolite and other inorganic molecular sieve membranes have shown potential for separations based on molecular size and shape because of their small pore sized, typically less than 1 nm, and their narrow pore size distribution. The high thermal and chemical stability of these inorganic crystals make them ideal materials for use in high temperature ...

Optimal activated carbon for separation of CO2 from (H2 + CO2) gas mixture
Petroleum Science, 2018 Seven types of activated carbon were used to investigate the effect of their structure on separation of CO2 from (H2 + CO2) gas mixture by the adsorption method at ambient temperature and higher pressures. The results showed that the limiting factors for
