US Patent:

47351934, Apr 5, 1988

Filed:

Feb 8, 1985

Appl. No.:

6/699897

Inventors:

Santi Kulprathipanja - Hoffman Estates IL
Edward W. Funk - Highland Park IL
Sudhir S. Kulkarni - Hoffman Estates IL
Y. Alice Chang - Des Plaines IL

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

B01D 1300

US Classification:

127 463

Abstract:

A process for separating a monosaccharide from an aqueous solution comprising monosaccharides and a second component comprising a polysaccharide. The mixture is contacted with a mixed matrix membrane comprising a adsorbent or molecular sieve material dispersed in an organic polymer in which the monosaccharide has a greater steady state permeability than the polysaccharide. The monosaccharide passes through the membrane, and is recovered. Particular mixed matrix membranes found to be useful in separating mono from polysaccharides are silicalite, gamma-alumina, activated carbon or a calcium exchanged Y-zeolite dispersed in cellulose acetate or polyelectrolyte complex polymers.

International Classification:

B05D 312
B05D 500

US Classification:

427 57

Abstract:

Gas separation membranes which possess improved characteristics as exemplified by selectivity and flux may be prepared by coating a porous organic polymer support with a solution or emulsion of a plasticizer and an organic polymer, said coating being effected at subatmospheric pressures in order to increase the penetration depth of the coating material.

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

B01D 1300

US Classification:

210651

Abstract:

Mixtures of heavy oils and light hydrocarbons may be separated by passing the mixture over a polymeric membrane which comprises a polymer capable of maintaining its integrity in the presence of hydrocarbon compounds at temperature ranging from about ambient to about 100. degree. C. and pressures ranging from about 50 to about 1000 psi. The membranes which possess pore sizes ranging from about 10 to about 500 Angstroms are cast from a solvent solution and recovered.

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

C10M 1100

US Classification:

208251R

Abstract:

Heavy crude oils which contain metal contaminants such as nickel, vanadium and iron may be separated from light hydrocarbon oils by passing a solution of the crude oil dissolved in a cycloparaffinic hydrocarbon solvent containing from about 5 to about 8 carbon atoms by passing through a polymeric membrane which is capable of maintaining its integrity in the presence of hydrocarbon compounds. The light hydrocarbon oils which possess relatively low molecular weights will be recovered as the permeate while the heavy oils which possess relatively high molecular weights as well as the metal contaminants will be recovered as the retentate.

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

B01D 5914

US Classification:

55 16

Abstract:

A multicomponent membrane which may be used for separating various components which are present in a fluid feed mixture comprises a mixture of a plasticizer such as a glycol and an organic polymer cast upon a porous organic polymer support. The membrane may be prepared by casting an emulsion or a solution of the plasticizer and polymer on the porous support, evaporating the solvent and recovering the membrane after curing.

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

B01D 1300

US Classification:

210638

Abstract:

Mixtures of heavy oils and light hydrocarbons may be separated by passing the mixture through a polymeric membrane. The membrane which is utilized to effect the separation comprises a polymer which is capable of maintaining its integrity in the presence of hydrocarbon compounds and which has been modified by being subjected to the action of a sulfonating agent. Sulfonating agents which may be employed will include fuming sulfuric acid, chlorosulfonic acid, sulfur trioxide, etc. , the surface or bulk modified polymer will contain a degree of sulfonation ranging from about 15 to about 50%. The separation process is effected at temperatures ranging from about ambient to about 100. degree. C. and pressures ranging from about 50 to about 1000 psig.
