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.

摘要： The present invention generally relates to vacuum pressure swing adsorption (VPSA) processes and apparatus to recover carbon dioxide having a purity of approximately ≧90 mole % from streams containing at least carbon dioxide and hydrogen (e.g., syngas). The feed to the CO2 VPSA unit can be at super ambient pressure. The CO2 VPSA unit produces three streams, a H2-enriched stream, a H2-depleted stream and a CO2 product stream. When the CO2 VPSA unit is installed between an SMR/shift reactor and a H2 PSA unit, hydrogen recovery is expected to be increased by extracting CO2, thereby increasing hydrogen partial pressure in the H2 PSA feed. The stream from the CO2 VPSA unit, normally used as fuel, is recycled as feed to increase CO2 recovery. The recovered CO2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR).
