System For Direct-Oxygenation Of Alkane Gases

US Patent:

7578981, Aug 25, 2009
Filed:

Mar 14, 2007
Appl. No.:

11/685852
Inventors:

Nathan A. Pawlak - Charlevoix MI, US
Robert W. Carr - Bloomington MN, US
Roger J Grunch - Charlevoix MI, US
Assignee:

Gas Technologies LLC - Walloon Lake MI
International Classification:

B01J 19/00
B01J 19/18
B01J 19/26
US Classification:

422224, 422129, 422188, 422189
Abstract:

An apparatus for alkyl oxygenate (e. g. , methanol) manufacture via partial oxidation of alkane (methane) has an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor. The injectively-mixed backmixing reaction chamber induces alkyl free radicals prior to input to the tubular-flow reactor. Injective intermixing of feed streams agitates the backmixing reaction chamber. In one embodiment, a variable position bulkhead axially moves to commensurately modify the backmixing reaction chamber and tubular-flow reactor volumes. In another embodiment, the tubular-flow reactor has a variable position quenching input. Both “hairbrush” and conical input inserts facilitate turbulent injective admixing of the input feed streams in the injectively-mixed backmixing reaction chamber. A condensing scrubber is also used for treating the output stream from the reaction system.

US Patent:

7687669, Mar 30, 2010
Filed:

Nov 18, 2008
Appl. No.:

12/273213
Inventors:

Nathan A. Pawlak - Charlevoix MI, US
Robert W. Carr - Bloomington MN, US
Roger J. Grunch - Charlevoix MI, US
Assignee:

Gas Technologies LLC - Walloon Lake MI
International Classification:

C07C 41/02
C07C 27/10
US Classification:

5689105, 568910
Abstract:

A method for alkyl oxygenate (e. g. , methanol) manufacture via partial oxidation of alkane (methane) uses an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor. Alkyl free radicals are induced in the backmixing reaction chamber prior to being fed through a flow-restriction baffle to the tubular-flow reactor. Injective intermixing of feed streams agitates the backmixing reaction chamber. In one embodiment, a variable position flow restriction baffle is axially moved to commensurately modify the backmixing reaction chamber and tubular-flow reactor volumes. In another embodiment, the tubular-flow reactor is quenched with a variable position quenching input. The method further provides for condensing the output stream from the reaction system in a condensing scrubber and also for recycling a portion of the scrubbed output stream to the reactor system.

US Patent:

7879296, Feb 1, 2011
Filed:

Mar 14, 2007
Appl. No.:

11/685879
Inventors:

Nathan A. Pawlak - Charlevoix MI, US
Robert W. Carr - Bloomington MN, US
Roger J Grunch - Charlevoix MI, US
Assignee:

Gas Technologies LLC - Walloon Lake MI
International Classification:

B01J 19/00
B01J 19/26
US Classification:

422189, 422195, 422207, 422224, 422236
Abstract:

A reactor system for gas phase reacting of at least two fluid feed streams, where the reactor system has an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor. The injectively-mixed backmixing reaction chamber has a bulkhead that slides during real-time operation to either diminish or expand the internal volume of the backmixing reaction chamber. In one embodiment, the effective passageway space through the bulkhead is also variably adjustable. In another embodiment, the tubular-flow reactor shares the bulkhead so that axial bulkhead movement commensurately expands one reaction space while diminishing the other reaction space. Input gas streams enter the backmixing reaction chamber with sufficient velocity to turbulently agitate the contents of the injectively-mixed backmixing reaction chamber by injective intermixing of the alkane-containing gas feed stream and the oxygen-containing gas feed stream. A focal application is for direct (partial) oxidative conversion of natural gas to alkyl oxygenates.
