摘要：
A new adsorbent CO2-ONE for removal of acidic gases such as carbon dioxide and hydrogen sulfide was developed from hydrothermal reaction of natural limestone with natural kaolin via sodium hydroxide. Several synthesis conditions were employed such as initial concentration of NaOH, weight ratio of limestone to kaolin, reaction temperature and pressure. The produced Ca—Na—SiO2-Al2O3 samples were characterized using XRD and EDS and showed that a mixture of Gehlenite Ca2Al(Al1.22Si0.78O6.78)OH0.22 and Stilbite Na5.76Ca4.96(Al15.68Si56.32O144) with percentage of 43 and 57 was successfully produced, respectively. Another produced sample showed the presence of Gehlenite Ca2Al(Al1.22Si0.78O6.78)OH0.22, Stilbite Na5.76Ca4.96(Al15.68Si56.32O144) and Lawsonite CaAl2Si2O7OH2(H2O) with percentage of 4.1 and 7.4 and 88, respectively.
