Porous carbons loaded with magnesium oxide were prepared through one-step process. Poly(ethylene terephthalate) and natural magnesite were used as carbon source and MgO precursor, respectively. An impact of a temperature and relative amounts of raw components used for preparations on the textural parameters of resulting hybrid materials is presented and discussed. As found, pore structure parameters...
Molecular sieve properties of general-purpose carbon fibres (GPCFs) from different origins are studied. Selectivity of the materials for CO 2 and CH 4 separation and uptake of these gases are analysed and compared with a commercial pelleted carbon molecular sieve appropriate for this process. A set of four GPCFs, one of them commercially available, obtained from petroleum or coal tar...
Methane storage in two series of activated carbon fibres (ACF) has been studied. The two series have been prepared by activation with CO 2 and steam of a petroleum-pitch based carbon fibre. Methane isotherms have been carried out in a gravimetric system up to 4 MPa. ACF are very promising materials for this purpose because they are essentially microporous activated carbons. The paper analyzes...
