Molecularly engineering polymeric membranes for H 2 / CO 2 separation at 100–300 °C

Dual-functionalized mesoporous TiO(2) hollow nanospheres for improved CO(2) separation membranes.

Simultaneous improvement in CO2 permeability and CO2/N2 selectivity was obtained from mixed matrix membranes (MMMs) containing dual-functionalized mesoporous TiO2 hollow nanospheres (f-MTHS). Dual functionality resulted in the increased CO2 affinity and improved interfacial properties between inorganic nanofillers and the polymer matrix.

Polymeric Gas Separation Membranes: What Makes them Industrially more Attractive?

Bicyclic phosphines as ligands for cobalt catalysed hydroformylation. Crystal structures of [Co(Phoban[3.3.1]-Q)(CO)(3)](2) (Q = C(2)H(5), C(5)H(11), C(3)H(6)NMe(2), C(6)H(11)).

A range of tertiary bicyclic phosphine ligands derived from cis, cis-1,5-cyclooctadiene (Phoban family) was studied by batch autoclave reactions during the hydroformylation of a mixture of linear internal decenes using a cobalt catalyst system. Comparative runs were performed with PBu(3) as representative of standard trialkyl phosphine behaviour. The Phoban ligands comprise of a cyclooctyl bicy...

GCEP Final Report Advanced CO 2 / H 2 Separation Materials Incorporating Active Functional Agents

Polymeric membranes for preferential CO2 separation over H2 have been investigated in this project, which can be applicable, for example, in an integrated gasification combined cycle (IGCC) plant with CO2 capture and storage (CCS). Poly(amidoamine) (PAMAM) dendrimers have been employed as an effective agent for preferential CO2 separation in this project. Although PAMAM dendrimer containing mem...
