Improvement in liquid fuel product quality from reactions of grape marc with CO/H2O
(Elsevier BV, 2015-06-19)
Reactions of grape marc with CO/H2O have been investigated over a range of temperatures (320–425 C) with and without added sodium carbonate (Na2CO3) or sodium aluminate (NaAlO2) with a view to optimising liquid fuel quality. ...
Amine modified mesocellular siliceous foam (MCF) as a sorbent for CO2
(Elsevier, 2011-02-11)
Adsorption is considered a promising method for carbon capture. CO2 adsorbents take a variety of forms – but one approach is to fill mesoporous substrates with a polymeric CO2 selective sorbent. SBA-15 and mesocellular ...
CO2 adsorption by amine modified siliceous mesostructured cellular foam (MCF) in humidified gas
(Elsevier, 2013-11-27)
A set of branched and linear polyethyleneimine (PEI) modified mesocellular siliceous foams (MCF) were evaluated as adsorbents for CO2 capture at modestly elevated temperatures under conditions that simulate the vacuum swing ...
