In this work, a CO2 sorbent was prepared by immobilizing tetraethylenepentamine (TEPA) onto modified carbon nanotubes. Modification of carbon nanotubes (CNTs) using a KOH reagent was done to increase the surface area and pore volume of the CNTs. The prepared sorbents were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM),...
In this work, an inorganic-organic CO2 sorbent was prepared by immobilizing tetraethylenepentamine (TEPA) onto nanoporous titanium oxyhydrate (TiO(OH)2). The prepared sorbents were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) analyses. At the optimal...
The objective of this research was to develop composite CO2 sorbents for overcoming the shortcomings of the corresponding individual sorbents. The composite sorbents were synthesized with K2CO3, 3-aminopropyltriethoxysilane (APTES), tetraethylorthosilicate (TEOS) and dried either with supercritical or conventional technique. Comparative experiments demonstrated that supercritical fluid drying (SCFD)...
In this work, an inorganic-organic CO2 sorbent was prepared by immobilizing tetraethylenepentamine (TEPA) onto acid-modified nanosepiolite, a low cost and widely available clay. Nanosepiolite was pre-modified with acid treatment to enhance its surface area, increasing the surface area from 103.4 to 272.45m2/g. The prepared sorbents were characterized using X-ray diffraction, scanning electron microscopy,...
