WebMar 30, 2007 · ABSTRACT. Several separation schemes, involving liquid-liquid extraction procedures, were found to be theoretically feasible in order to separate Vanadium and Molybdenum based on computer simulation of the acid-base properties of these metals, where cationic and anionic (both mono and polynuclear) species are formed as the p H … WebApr 9, 2015 · Abstract. Direct methane conversion into aromatic hydrocarbons over catalysts with molybdenum (Mo) nanostructures supported on shape-selective zeolites is a promising technology for natural gas liquefaction. We determined the identity and anchoring sites of the initial Mo structures in such catalysts as isolated oxide species with a single Mo ...
