Abstract:
Herein disclosed is a method of producing value-added product from light gases, the method comprising: (a) providing light gases comprising at least one compound selected from the group consisting of C1-C6 compounds and combinations thereof; (b) intimately mixing the light gases with a liquid carrier in a high shear device to form a dispersion of gas in the liquid carrier, wherein the dispersion is supersaturated with the light gases and comprises gas bubbles at least some of which have a mean diameter of less than or equal to about 5 micron(s); (c) allowing the value-added product to form and utilizing vacuum to extract unreacted light gases from the liquid carrier; (d) extracting the value-added product; wherein the value-added product comprises at least one component selected from the group consisting of higher hydrocarbons, hydrogen, olefins, alcohols, aldehydes, and ketones. A system for producing value-added product from light gases is also disclosed.
Abstract:
A method of producing value-added product from refinery-related gas, the method comprising: providing a refinery-related gas comprising at least one selected from C1-C8 compounds; intimately mixing the refinery-related gas with a liquid carrier in a high shear device to form a dispersion of gas in the liquid carrier, wherein the gas bubbles in the dispersion have a mean diameter of less than or equal to about 5m; and extracting value-added product comprising at least one component selected from higher hydrocarbons, olefins and alcohols. A system for producing value-added product from refinery-related gas comprising: at least one high shear device comprising at least one rotor and at least one complementarily-shaped stator; apparatus for the production of a refinery-related gas comprising one or more of C1-C8 compounds; and a pump configured for delivering a liquid stream comprising the liquid carrier to the high shear device.
Abstract:
Herein disclosed is a method, comprising: forming a dispersion under high shear comprising gas bubbles of an oxidant dispersed in a liquid phase, wherein the bubbles have a mean diameter of less than 1.5 micron; and contacting the dispersion with an oxidation catalyst to produce a product stream, wherein the product stream comprises a substance selected from the group consisting of dicarboxylic acid, benzoic acid, 2- methylbenzoic acid, 3- methylbenzoic acid, 4-methylbenzoic acid, and phthalic anhydride. In some cases, forming the dispersion under high shear comprises introducing the oxidant and the liquid phase into a high shear device comprising at least one rotor and at least one complementarily-shaped stator. Herein also disclosed is a system for producing a substance selected from the group consisting of dicarboxylic acid, benzoic acid, 2- methylbenzoic acid, 3- methylbenzoic acid, 4-methylbenzoic acid, and phthalic anhydride.
Abstract:
Herein disclosed is a method of producing synthesis gas from carbonaceous material, the method comprising: (a) providing a mixture comprising carbonaceous material and a liquid medium; (b) subjecting the mixture to high shear under gasification conditions whereby a high shear-treated stream comprising synthesis gas is produced; and (c) separating a product comprising synthesis gas from the high shear-treated stream. Herein also disclosed is a method for producing a liquid product. The method comprises forming a dispersion comprising gas bubbles dispersed in a liquid phase in a high shear device, wherein the average gas bubble diameter is less than about 1.5 μm; contacting the dispersion with a multifunctional catalyst to form the liquid product; and recovering the liquid product. In an embodiment, the liquid product is selected from the group consisting of C2+ hydrocarbons, C2+ oxygenates, and combinations thereof.
