2011/12/29
During processing of Athabasca oil sands, the finely divided solids form an aqueous suspension, which ultimately stabilizes as a gel-like structure retaining up to 90% of the process water. This gelli...
High Surface Area Solids Obtained by Reaction of Montmorillonite with Zirconyl Chloride
Adsorption Exchange Hydroxyzirconium Montmorillonite Surface Zirconium
<
2012/2/9
Exchange reactions of Na-montmorillonite with zirconyl chloride solutions give products with basal spacings near 18 Å which are stable to 500°C and have surface areas of the order of 300–400 m2/...
