Abstract:
Charge compositions containing aqueous mixtures of organic oxygenates may be separated by pervaporation through a membrane assembly containing a porous ceramic support bearing as separating layer, a membrane of cured polyvinyl alcohol which has been cross-linked as with glutaraldehyde.

Abstract:
Mixture of gases such as hydrogen/carbon dioxide may be separated by use of membrane formed by reaction of an aluminium alkoxide with water vapor at high temperatures and pressures.
Abstract:
A process for the partial oxidation of a sulfur- and silicate-containing carbonaceous fuel to produce a synthesis gas with reduced sulfur content which comprises partially oxidizing said fuel at a temperature in the range of 1800.degree.-2200.degree. F. in the presence of a temperature moderator, an oxygen-containing gas and a sulfur capture additive which comprises an iron-containing compound portion and a sodium-containing compound portion to produce a synthesis gas comprising H.sub.2 and CO with a reduced sulfur content and a molten slag which comprises (i) a sulfur-containing sodium-iron silicate phase and (ii) a sodium-iron sulfide phase. The sulfur capture additive may optionally comprise a copper-containing compound portion.
