Mahmoud M. El-Halwagi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11591213
    Abstract: The present subject matter is directed to a system and method for producing carbon and syngas from carbon dioxide (CO2). The system includes a first reactor (7) for producing solid carbon (15) from a feed including CO2 and a volatile organic compound such as methane (1), and a second reactor (20) for producing syngas. Reactions in the first reactor (7) are conducted in a limited oxygen atmosphere. The second reactor (20) can use dry reforming, steam reforming, and/or partial oxidation reforming to produce the syngas (22).

  • Publication number: 20210061655
    Abstract: A method and system for producing syngas The method includes providing separate streams of oxygen gas and hydrogen gas, the oxygen gas and the hydrogen gas generated from electrolysis of water. The separate stream of oxygen gas is introduced into a reforming module configured to generate a reformed syngas feed, where the oxygen gas oxidizes natural gas supplied to the reforming module. The separate stream of hydrogen gas and the reformed syngas feed are mixed to adjust a ratio of hydrogen gas to carbon monoxide gas (H2:CO) to produce a syngas product feed. The system includes a reforming module to receive a stream of oxygen gas, where the oxygen gas oxidizes natural gas supplied to the reforming module to generate a reformed syngas feed. The system includes a mixing module to receive the reformed syngas feed and a stream of hydrogen gas to thereby adjust a ratio of hydrogen gas to carbon monoxide gas (H2:CO) in a syngas product feed released from the mixing module.

  • Patent number: 8802905
    Abstract: A unique, integrated non-obvious pathway to convert biomass to biofuels using integration of chemical processes is described herein. The present invention is simple, direct, and provides for the shortest or minimum path between biomass and transportation fuels with alcohols as intermediates, while avoiding hydrogen use during processing. Furthermore, the present invention allows the manufacture of “drop-in” substitutable fuels to be used as-is without modifications instead of conventional petroleum based fuels. The processing described herein is done under mild conditions, under relatively low pressures and temperatures, and under non-corrosive conditions obviating use of special equipment or materials.
