Hydrophobic Ceramic Membranes for Water Desalination

Hydrophilic ceramic membranes (tubular and planar) made of TiO2 and Al2O3 were efficiently modified with non-fluorinated hydrophobic grafting molecules. As a result of condensation reaction between hydroxyl groups on the membrane and reactive groups of modifiers, the hydrophobic surfaces were obtained. Ceramic materials were chemically modified using three various non-fluorinated grafting agent...

Dense Ceramic Membranes for Hydrogen Separation

In the 1980s and 1990s, the development of oxygen ion conductors for solid electrolytes, as well as mixed oxygen–electron conductors as electrodes for solid oxide fuel cells, brought scientists to envision a possibility of mixed-conducting oxygenpermeable ceramic membranes. Today this field is well established, and ceramic membranes are close to implementation in processes for oxygen extraction...

Dense Ceramic Membranes for Hydrogen Separation

Novel cermet (i.e., ceramic-metal composite) membranes have been developed for separating hydrogen from product streams that are generated during coal gasification, methane partial oxidation, and watergas shift reactions. The hydrogen permeation rate in the temperature range of 600-900°C has been measured for three classes (ANL-1, -2, and -3) of cermet membranes. ANL-3 membranes provided the hi...
