Název v původním jazyce

Preparation of MgO Catalytic Support in Shaped Mesoporous High Surface Area Form

Popis výsledku v původním jazyce

Shaped MgO support of high surface area (307-397 m2 g-1), mesoporous texture and good hardness was prepared by hydration/calcination of commercial, low surface area MgO. For MgO(w), the paste MgO/H2O was kneaded, extruded, dried at room temperature and calcined in a fixed bed reactor at high space velocity of air flow. The samples MgO(m) and MgO(et) were prepared by the new simplified sol-gel method: MgO(w) was treated with methanol/water and ethanol/water mixture, respectively, and calcined. Texture ofour MgO was evaluated by N2 adsorption and compared with our data for commercial Al2O3 supports and literature data for MgO prepared by the original sol-gel method. Our MgO exhibited a similar XRD peaks broadening as described in literature for the original sol-gel MgO, but somewhat different ratio of the heights of XRD peaks. The weight of our MgO increased by about 40% at ambient air, indicating deep hydration of the sample.
