US Patent:

7132090, Nov 7, 2006

Filed:

May 2, 2003

Appl. No.:

10/428533

Inventors:

Daniel Dziedzic - Rochester Hills MI, US
Kenneth B Gross - Troy MI, US
Robert A Gorski - Sterling Heights MI, US
John T Johnson - Sterling Heights MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B01D 53/04

US Classification:

423230, 4234191

Abstract:

A process for selectively removing carbon dioxide from a gaseous stream by converting the carbon dioxide to a solid, stable form is provided. In a sequestration process, carbon dioxide enriched air is passed through a gas diffusion membrane to transfer the carbon dioxide to a fluid medium. The carbon dioxide rich fluid is then passed through a matrix containing a catalyst specific for carbon dioxide, which accelerates the conversion of the carbon dioxide to carbonic acid. In the final step, a mineral ion is added to the reaction so that a precipitate of carbonate salt is formed. This solid mineral precipitate can be safely stored for extended periods of time, such as by burying the precipitate in the ground or depositing the precipitate into storage sites either on land or into a body of water. An apparatus for removing carbon dioxide from a gaseous stream is also provided.

US Classification:

422139, 422143, 422147, 422168

Abstract:

A fluidized-bed reactor comprising a chamber defining a hollow interior region and having a lower surface; a first input for introducing a contaminated gas into the hollow interior region; a plurality of catalyst nanoparticles within the hollow interior region and located on the lower surface, and a fluidizing input for introducing a fluidizing material into the hollow interior region, said fluidizing input having an outlet directed at the lower surface of the chamber, wherein the introduction of the fluidizing material directed at the lower surface fluidizes at least a portion of the catalyst nanoparticles located on the lower surface to create a gaseous dispersion of catalyst nanoparticles that reacts with the contaminated gas to produce a decontaminated gas.

International Classification:

C12N 11/16
C12N 9/00

US Classification:

435174

Abstract:

An immobilized protein catalyst is prepared by applying an adhesive to a polymeric support, applying a layer of a globular protein over the layer of adhesive, binding a crosslinking agent to the protein layer, and binding the protein catalyst by reaction with the crosslinking agent.
