Abstract
A process for separating at least one component from a mixture of components which comprises contacting the mixture with a sorbent structure comprising a film of interconnected zeolite crystals bonded to a substrate, said sorbent structure being characterized by a value r representing the mg of zeolite/cm.sup.2 of substrate surface and a value e representing the coating efficiency as mg of bonded zeolite/mg of YO.sub.2 initially in the synthesis mixture, wherein r is at least 0.5 and e is at least 0.05.
Claims19
A process for separating at least one component from a mixture of components in the vapor or liquid phase having differential sorption characteristics with respect to a sorbent structure, wherein said at least one component is selectively adsorbed on said sorbent in preference to at least one other component in said mixture of components said sorbent structure comprising a film of interconnected zeolite crystals bonded to a substrate surface, said structure having been manufactured by the method comprising
- contacting the substrate with a chemical reaction mixture capable of forming the zeolite film under crystallization conditions, wherein said reaction mixture comprises a H.sub.2 O/YO.sub.2 molar ratio of at least about 25 when the YO.sub.2 /X.sub.2 O.sub.3 molar ratio is greater than about 400, a H.sub.2 O/YO.sub.2 ratio of at least about 35 when the YO.sub.2 /X.sub.2 O.sub.3 ratio is greater than about 150 and less than about 400, and a H.sub.2 O/YO.sub.2 ratio of at least about 45 when the XO.sub.2 /X.sub.2 O.sub.3 ratio is less than about 150;
- and wherein Y is a tetravalent element and X is a trivalent element.
