| Abstract: | Commercially available silica gel is
chemically modified for carbon dioxide capture. Calcinated silica gel of
certain particle size functionalized with amine using two different methods,
wet impregnation and grafting via silane chemistry has been employed as a
porous media. The prepared material is characterized by Fourier transform
infrared, scanning electron microscopy, energy dispersive analysis of X-rays,
thermogravimetry and N2 physisorption techniques. Gas uptake
measurements have been carried out to ascertain the CO2 capture
capacity of the amine functionalized material. The experiments have been
carried out at moderate pressure and temperature range to ascertain its
potential for easy scale up. |
