  • Gasification systems and associated processes
    Patent number: 8765017
    Abstract: Gasification systems and associated processes are disclosed herein. In one embodiment, a gasification process includes simultaneously supplying a carbonaceous material and steam to a gasifier, the gasifier containing a liquid volume containing at least about 10% by weight of iron oxide (FexOy where x and y are positive integers). The gasification process also includes performing a gasification reaction between the carbonaceous material and steam in the liquid volume, facilitating the gasification reaction with the iron oxide in the liquid volume, and producing a gas from the gasification reaction, the gas containing carbon monoxide (CO) and hydrogen (H2).

  • ALGAE PRODUCTION SYSTEMS AND ASSOCIATED METHODS
    Publication number: 20100170149
    Abstract: Algae production systems and associated methods are disclosed herein. In one embodiment, for example, an algae production system can include a plurality of elongated growth receptacles arranged in a desired configuration at a work site. The growth receptacles have a generally non-circular cross-sectional profile and are configured to hold an algae culture, and wherein the individual growth receptacles have a generally non-circular cross-sectional profile. The system can also include a carbon dioxide (CO2) subsystem configured to supply provide CO2-enriched air to the growth receptacles, a fresh medium subsystem configured to supply a fertility solution to the growth receptacles, and a harvesting subsystem.
