专利号:US-9649619-B2 优先权日:2014-01-29 标题:Sodium-calcium-aluminosilicate column for adsorbing CO2 发明人:SHAWABKEH REYAD AWWAD; FAQIR NAIM MOH'D; BKOUR QUSAY YOUSEF 权利人:UNIV KING FAHD PET & MINERALS 摘要:A new adsorbent CO 2 -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 Ca 2 Al(A 1.22 Si 0.78 O 6.78 )OH 0.22 and Stilbite Na 5.76 Ca 4.96 (Al 15.68 Si 56.32 O 144 ) with percentage of 43 and 57 was successfully produced, respectively. Another produced sample showed the presence of Gehlenite Ca 2 Al(Al 1.22 Si 0.78 O 6.78 )OH 0.22 , Stilbite Na 5.76 Ca 4.96 (Al 15.68 Si 56.32 O 144 ) and Lawsonite CaAl 2 Si 2 O 7 OH 2 (H 2 O) with percentage of 4.1 and 7.4 and 88, respectively.

FOR SEVERAL MINUTES. A IS PREPARED BY REFLUXING META KAOLIN IN 10% ZEOLITE A IS PREPARED BY REFLUXING META KAOLIN IN 10% SODIUM HYDROXIDE SOLUTION OR BY ANY OTHER ZEOLITE A SYNTHESIS. SUCH SODIUM ZEOLITE IS AT LEAST 50% ION-EXCHANGED TO THE CALCIUM FORM TO PROVIDE SAID PRECUSOR PELLETS. THE CERAMIC FOAM PARTICLES ARE IMPREGNATED WITH A LIQUID CONTAINING A METAL COMPONENT. THEREAFTER THE IMPREGNATED PARTICLE IS HEATED TO BOND THE CATALYTIC METAL TO THE FOAMED CERAMIC PARTICLE. SUCH PARTICLES COMPRISING CATALYTIC METAL COMPONENTS ON CERAMIC FOAM ARE CATALYSTS FOR REACTIONS CONDUCTED AT ELEVATED TEMPERATURES, COMPRISING HYDROLYSIS OF HYDROCARBONACEOUS MATERIAL, OXIDATION REACTIONS, AND HYDROGENATIVE AROMATIZATION OF HYDROCARBONACEOUS MATERIALS.
