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:

C10G 104

US Classification:

208 11LE

Abstract:

A solvent extraction process for tar sands is disclosed wherein a low boiling solvent having a normal boiling point of from 20. degree. to 70. degree. C. is used to extract tar sands. The solvent is mixed with tar sands in a dissolution zone, the solvent:bitumen weight ratio being maintained at from about 0. 5:1 to 2:1. This mixture is passed to a separation zone in which bitumen and inorganic fines are separated from extracted sand, the separation zone containing a classifier and countercurrent extraction column. The extracted sand is introduced into a first fluid-bed drying zone fluidized by heated solvent vapors, so as to remove unbound solvent from extracted sand while at the same time lowering the water content of the sand to less than about 2 wt. %. The so-treated sand is then passed into a second fluid-bed drying zone fluidized by a heated inert gas to remove bound solvent. Recovered solvent is recycled to the dissolution zone.

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.

International Classification:

C10G 104

US Classification:

208 11LE

Abstract:

This invention relates to a process for the extraction of bitumen from tar sands which comprises contacting the tar sand in an extraction zone with a paraffinic hydrocarbon solvent having from 5 to 9 carbon atoms at a ratio of from 2 to 10 parts solvent per part of bitumen present in the tar sand, maintaining the asphaltene fraction of said tar sands in suspension, separating a major portion of said solvent which contains a major amount of the bitumen dissolved therein along with the suspended asphaltene fraction from the extracted sand, passing the extracted sand along with a minor portion of said solvent and a minor amount of bitumen into a water contacting zone and therein contacting said extracted sand with sufficient water at a temperature of at least 100. degree. F. to separate substantially all of said minor amount of bitumen and said minor portion of solvent from said sand, separating said major solvent portion from the suspended asphaltenes and distilling said solvent from said major solvent portion to recover said major amount of bitumen. In a preferred embodiment, the extract from the water contacting zone is centrifuged to separate fines and water from the bitumen and solvent, said minor amount of bitumen is removed from the solvent, e. g.

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.

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.

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.
