ABS copolymer-activated carbon mixed matrix membranes for CO 2/CH4 separation
(Elsevier Science, 2004-11-01)
The performance of various novel mixed matrix composite (MMC) membranes for separation of CO2 from CH4 was investigated as a function of carbon loading. Acrylonitrile-butadiene-styrene (ABS) copolymer was used as the polymer ...

El género Chromolaena DC. (Asteraceae-Eupatorieae) está conformado por cerca de 170 especies que se distribuyen desde el sur de los Estados Unidos hasta el sur de Argentina, con la mayor concentración de especies en Brasil. ...
Already used and candidate polymeric membranes for CO2 separation plants
(Elsevier, 2018)
This chapter presents the already in used polymeric membranes and the potential candidates for the CO2 acid gas separation. Mainly, this work describes the characteristics of each membrane arrangement and the differences ...
Separation of CO2 from CH4 and CO2 capture in the presence of water vapour in NOTT-400
(Royal Society Of Chemistry, 2015-01-16)
From a binary equimolar gas-mixture of CO2 and CH4, NOTT-400 shows CO2 separation from CH4. By kinetic uptake experiments, this material confirms a maximum of 4.3 wt% CO2 capture at 30 8C and a significant 2-fold increase ...
Design assessment of polymeric membranes modules to separate carbon dioxide from a binary mixture with methane
(Elsevier Science SA, 2020-04)
This work presents the performance assessment of diverse membrane arrangements to separate carbon dioxide (CO2) from a binary mixture with methane (CH4). For the purpose, we employ computer modeling to represent different ...
Waterborne poly(urethane-urea) gas permeation membranes for CO2/CH4 separation
(2018-03-15)
In this work, dense membranes from aqueous dispersions of poly(urethane-urea) (PUU) based on poly(propylene glycol) (PPG) and a block copolymer composed of poly(ethylene glycol) (PEG) and poly(propylene glycol) (PPG), ...
Photolysis of CH3CHO at 248 nm: Evidence of triple fragmentation from primary quantum yield of CH3 and HCO radicals and H atoms
(American Institute of Physics, 2014-06)
Radical quantum yields have been measured following the 248 nm photolysis of acetaldehyde, CH3CHO. HCO radical and H atom yields have been quantified by time resolved continuous wave Cavity Ring Down Spectroscopy in the ...
Combination of MOF and zeolite for mixed matrix membranes
(Wiley VCH Verlag, 2011-09)
Mixed‐matrix membranes (MMMs) were prepared by combinations of two different kinds of porous fillers [metal‐organic frameworks (MOFs) HKUST‐1 and ZIF‐8, and zeolite silicalite‐1] and polysulfone. In the search for filler ...
Removal of CO2 from CH4 and CO2 capture in the presence of H2O vapour in NOTT-401
(Royal Society of Chemistry, 2015-04-13)
From a binary equimolar gas-mixture of CO2 and CH4, NOTT-401 exhibits CO2 separation from CH4. By kinetic uptake experiments, NOTT-401 shows a maximum of 1.47 wt% CO2 capture at 30 °C and a significant 7-fold increase ...
Gas sorption, permeation and separation of ABS copolymer membrane
(Elsevier Science, 2003-08-15)
This work examines the gas transport and sorption properties of a commercial acrylonitrile-butadiene-styrene (ABS) copolymer (Lustran®246), containing 60% styrene, 27% acrylonitrile and 13% butadiene. Permeability, diffusion ...
